The Golden Rules for Working With LOGO!

There are some simple rules to following when entering programs:

2-Finger Combination: Parameterization Mode

Pressing ESC and OK simultaneously

The 2-finger combination switches LOGO! to parameterization mode. In parameterization mode, the program continues to run in LOGO!.

You can select the following functions:

•	Set Clock

•	Set Param
Set Param lets you change the values of the parameters that are marked with a ‘+’ in programming mode. Parameters that are marked with a ‘-’ are not displayed and cannot be changed.

3-Finger Combination: Programming Mode

Pressing [image], [image] and OK simultaneously

The 3-finger combination switches LOGO! to programming mode. In programming mode, you enter a circuit or change an existing circuit. As far as LOGO! is concerned, a circuit is a program.

LOGO!Soft also makes use of a 3-finger combination .

Switching Between Summer and Winter Time

The function is only available with LOGO! ...L versions.

To call it in RUN:

Press OK and [image] or [image] simultaneously.

Each time you do this in RUN, you switch LOGO! an hour forward or back.

From Output to Input

You always program from the output to the input. You connect new function blocks to the input of an existing block or directly to an output.

Cursor as an Underscore: Move the Cursor

When the cursor takes the form of an underscore, you can use the four cursor keys to move the cursor anywhere in the program.

Cursor as a Solid Block: Make an Entry

When the cursor is a flashing solid block, you can choose from the menus a function block or connection for an input. You can do this using the [image] and [image] keys. To conclude your input, press the OK key.

ESC: One Step Back

When you press the ESC key, you go back to the previous step. If LOGO! cannot go back another step, it returns to the previous menu.

When the cursor appears in the form of an underscore and you press the ESC key, LOGO checks whether the circuit is complete. If it is not, LOGO! automatically displays the inputs that are not yet wired. Unwired inputs are identified by a question mark. The circuit is not complete until all the inputs are wired. LOGO! only saves complete circuits.

OK: Accept

By pressing the OK key, you accept an input.


Entering a Program

To enter a program, proceed as follows:

1.	Switch LOGO! to programming mode (3-finger combination).

2.	From the main menu, choose Program.

To do this, use the [image] and [image] keys to select Program, and then press the OK key.

3.	From the programming menu, choose Edit Prg.

To do this, use the [image] and [image] keys to select Edit Prg, and then press the OK key.

Result: The first output (Q1) is displayed.

You can now enter the circuit for the output.

Press the OK key. Then select the Co, GF or SF list. Select a function or connector from the list, and press the OK key. The block corresponding to the function or the connector is inserted in the program.

If you cannot select any more function blocks, your program may be too large. Read the section on memory requirements and limitations on program size.

Follow the golden rules for working with LOGO!.


Changing a Program

It’s very easy to change a program (circuit) in LOGO!:

Switch to programming mode.

1.	From the main menu, choose Program.

To do this, use the [image] and [image] keys to select Program, and then press the OK key.

2.	From the programming menu, choose Edit Prg.

To do this, use the [image] and [image] keys to select Edit Prg, and then press the OK key.

Result: The first output (Q1) is displayed.

Move the cursor to the point at which you want to make a change.

Press the OK key, and enter the new wiring. When you enter a new block, the block or input previously connected at this point is connected to the uppermost input of the new block.

Note
If you want to select a block in order to replace it with a function block with a different function (e.g. OR instead of AND), bear in mind that you can only replace blocks with the same number of inputs or the same number of parameters.

Follow the golden rules for working with LOGO!.

If you cannot select any more function blocks, your program may be too large. Read the section on memory requirements and limitations on program size.

LOGO! Versions

Compatibility Table for Downward Compatibility


Standard Module

The module can be used in all LOGO! versions. The programs stored can be interchanged in accordance with the rules described above in the Upward Compatibility section.


Program Module with Remanence

This module can only be used in the LOGO! ...L... versions. The programs stored can be interchanged freely between these models.

The module must always be inserted so that remanent data can be stored. In the event of a power failure or on power OFF, LOGO! saves the remanent data to the module inserted.

Functions whose data can be stored as remanent data:

Function	Remanent
Pulse relay	The switch state is stored
Latching relay	The switch state is stored
Up and down counter	The internal counter reading is stored
Operating hours counter	The time elapsed is stored


Program Module With Know-how Protection and Remanence

This module can only be used in the LOGO! ...L... versions. Once a program has been stored in this module, it can neither be looked at, copied nor changed. I.e. your data is protected.

The module must remain inserted in LOGO! the whole time the system is operating for the program stored in this way to run.

In the event of a power failure and on power OFF, LOGO! saves the remanent data to the module inserted.


Switching LOGO! On

When you switch LOGO! on (i.e. connect it to the power supply), it does the following things:

1.	Establishes whether there is a program on the program module.

2.	If there is a valid program on the program module, LOGO! copies it from the program module automatically and saves it so that it is secure against power failure. If there is no program on the program module, or if there is no program module inserted (i.e. the cover is on the shaft instead), LOGO! works with the program stored inside it.

3.	LOGO! works with the copied or existing program.

4.	If there is no valid program in LOGO!, the following words appear on LOGO!’s display: No Program


LOGO!s Functions
LOGO!’s Functions

The following functions are available to you for entering blocks and connectors:

Connectors (Co)

Basic functions (GF)

Special functions (SF)

Blocks (BN)

Additional functions


Connectors (Co)

You can connect connectors to the inputs of blocks. LOGO! recognizes the following connectors:

x

If you do not want to wire an input, assign it an x (in the logic table, x=1 for AND, NOT, NAND. In the case of all other blocks, x=0).

I1, I2, I3, I4, I5, I6, 	I7, I8, I9, I10, I11, I12, 	Ia1, Ia2, Ia3, Ia4

If you want to connect one of LOGO!’s input connectors with a block, simply enter the name of the connector.

Inputs higher than I6 are only available in LOGO!...L... versions; inputs Ia1 to Ia4 are only available in LOGO!...LB11 versions.

Q1, Q2, Q3, Q4, 	Q5, Q6, Q7, Q8, 	Qa1, Qa2, Qa3, Qa4

If you want to connect one of LOGO!’s output connectors with a block, simply enter the name of the connector.

Outputs higher than Q4 are only available in LOGO!...L... versions; outputs Qa1 to Qa4 are only available in LOGO!...LB11 versions.

hi

If you want the state of a block’s input always to be ‘1’, enter hi for it (hi stands for high).

lo

If you want the state of a block’s input always to be ‘0’, enter lo for it (lo stands for low).

See OR

See NOT

See NAND (and not)

See NOR (or not)

See XOR (either or)


AND

The series connection of a number of normally open contacts is represented in a circuit diagram as follows:

In LOGO! this is an AND block. The symbol for AND is as follows:

The block is called AND because its output (Q) has the state 1 only when I1 and I2 and I3 have the state 1 (i.e. they are closed).

Logic table for AND:

I1	I2	I3	Q
0	0	0	0
0	0	1	0
0	1	0	0
0	1	1	0
1	0	0	0
1	0	1	0
1	1	0	0
1	1	1	1

The following applies to AND: x = 1
(x means the input is not used.)


OR

The parallel connection of a number of normally open contacts is represented in a circuit diagram as follows:

In LOGO! this is an OR block. The symbol for OR is as follows:

The block is called OR because its output (Q) always has the state 1 when I1 or I2 or I3 has the state 1 (i.e. closed). In other words, at least one input must have the state 1.

Logic table for OR

I1	I2	I3	Q
0	0	0	0
0	0	1	1
0	1	0	1
0	1	1	1
1	0	0	1
1	0	1	1
1	1	0	1
1	1	1	1

The following applies to OR: x = 0
(x means the input is not used.)


NOT

An inverter is represented in a circuit diagram as follows:

In LOGO! this is a NOT block. The symbol for NOT is as follows:

The block is called NOT because the output (Q1) has the state 1 when the input has the state 0, and vice versa. In other words NOT inverts the state at the input.

The advantage of NOT is, for example, that you no longer require any normally closed contacts for LOGO!. You can use a normally open contact and convert it to a normally closed contact using the NOT block.

Logic table for NOT

I1	Q
0	1
1	0

The following applies to NOT: x = 1
(x means the input is not used.)


NAND

The parallel connection of a number of normally closed contacts is represented in a circuit diagram as follows:

In LOGO! this is a NAND block. The symbol for NAND is as follows:

The block is called NAND because its output (Q) only has the state 0 if I1 and I2 and I3 have the state 1 (i.e. are closed).

Logic table for NAND

I1	I2	I3	Q
0	0	0	1
0	0	1	1
0	1	0	1
0	1	1	1
1	0	0	1
1	0	1	1
1	1	0	1
1	1	1	0

The following applies to NAND: x = 1
(x means the input is not closed.)


NOR

The series connection of a number of normally closed contacts is represented in a circuit diagram as follows:

In LOGO! this is a NOR block. The symbol for NOR is as follows:

The output of the NOR block is only switched on (state 1) when all the inputs are switched off (state 0). As soon as any of the inputs is switched on (state 1), the output is switched off.

The block is called NOR because its output (Q) only has the state 1 when all the inputs have the state 0. As soon as any of the inputs takes on the state 1, the output of NOR has the state 0.

Logic table for NOR

I1	I2	I3	Q
0	0	0	1
0	0	1	0
0	1	0	0
0	1	1	0
1	0	0	0
1	0	1	0
1	1	0	0
1	1	1	0

The following applies to NOR: x = 0
(x means the input is not used.)


XOR

An OR-ELSE circuit consists of the series connection of two changeover contacts. It is represented in a circuit diagram as follows:

In LOGO! this is an XOR block. The symbol for XOR is as follows:

The output of XOR has the state 1 when the states of the inputs differ.

Logic table for XOR

I1	I2	Q
0	0	0
0	1	1
1	0	1
1	1	0

The following applies to XOR: x = 0
(x means the input is not used.)

Memory Requirements and Limitations on Program Size


On-Delay

Wiring	Description
Trg input	You start the time for the on-delay by means of the Trg input (Trg stands for trigger).
T parameter	T is the time after which the output is switched on (output signal changes from 0 to 1).
Q output	Q switches on once the parameterized time T has expired if Trg is still set.

Timing diagram

When the state at the Trg input changes from 0 to 1, the time Ta begins to elapse (Ta is the current time in LOGO!). If the state at the Trg input remains 1 for long enough, the output is set to 1 after the time T has elapsed (there is a delay between the input being switched on and the output coming on).

If the state at the Trg input changes back to 0 before the time T elapses, the time is reset.

The output is reset to 0 when the Trg input has the state 0.

After a power failure, the time that has elapsed is reset.


Off-Delay

Wiring	Description
Trg input	You start the time for the off-delay with the negative edge (change from 1 to 0) at the Trg input (Trg stands for trigger).
R input	You reset the time for the off-delay and set the output to 0 via the R (reset) input (R has priority over Trg).
T parameter	T is the time after which the output is switched off (the output signal changes from 1 to 0).
Q output	Q switches on when Trg is sent and remains switched on until T expires.

When the Trg input takes on the state 1, the output (Q) switches to 1 immediately. If the state of Trg changes from 1 to 0, LOGO!’s current time Ta is started and the output remains set. If Ta reaches the values set via T (Ta=T), the output (Q) is reset to 0.

If the Trg input is switched on and off again, the time Ta starts again.

You reset the time Ta and the output via the R (reset) input before the time Ta has elapsed.

After a power failure, the time that has elapsed is reset.


Pulse Relay

Wiring	Description
Trg input	You use the Trg input (Trg stands for trigger) to switch the Q output on and off.
R input	You use the R input (reset) to reset the pulse relay and set the output to 0 (R has priority over Trg).
Par parameter	Par is only available in LOGO!...-L... versions. You can use this parameter to switch remanence on and off. Rem:  off = no remanence on = the state can be stored as a remanent one
Q output	Q switches on when Trg is sent, and off again the next time Trg is sent.

Timing diagram

Every time the state of the Trg input changes from 0 to 1, the state of the output (Q) changes (i.e. it is switched on or off). You reset the pulse relay to its initial state via the R input. After power on or reset, the pulse relay is reset and the output (Q) changes to 0.

State after power on

All LOGO! versions without program module	All LOGO! ...L... versions with red or yellow program module
The pulse relay is always reset and the Q output always set to 0 after power on.	If remanence has not been parameterized, the pulse relay is reset and the Q output set to 0 after power on.
	If remanence has been parameterized, the state that was current before LOGO! was switched off is set after power on.
Applications

Hall/corridor lighting


Clock (Time Switch)

A clock is only available in LOGO! versions that have the letter C (for clock) in their name (e.g. LOGO! 230 RC).

Each clock has 3 cams.

The block for the clock is as follows:

Parameter No1, No2, No3
You use the No parameters to set the switch-on and switch-off times for the three cams of the clock (see also Setting the Clock).

The parameter for a cam looks like this:

B01:No1
Day=Mo	+	Day of the week (Mo for Monday); + See Showing and Hiding Parameters
On =06:00		Switch-on time (6.00 hours)
Off=09:00		Switch-off time (19.00 hours)
Day of the week

You can set the following:
Su	Sunday
Mo	Monday
Tu	Tuesday
We	Wednesday
Th	Thursday
Fr	Friday
Sa	Saturday
Mo..Fr	Every day from Monday to Friday
Mo..Sa	Every day from Monday to Saturday
Mo..Su	Every day from Monday to Sunday (i.e. every day)
Sa..Su	Saturday and Sunday

Switch-on time

Any time between 00:00 and 23:59 hours
--:--  means there is no switch-on time.

Switch-off time

Any time between 00:00 and 23:59 hours
--:--  means there is no switch-off time.

Clock buffer

In LOGO! 230RC, the internal clock continues to run when there is a power failure. In other words, the clock has reserve power. How much reserve power LOGO! 230 RC has depends on the ambient temperature. At a temperature of 25°C, it has reserve power for 80 hours.

Cam overlap

You use the cams to set switch-on and switch-off times. At a switch-on time, the clock switches the output on unless it was already on; at a switch-off time, it switches the output off unless it was already off.

Priority

If you specify a switch-on time and a switch-off time at the same time for different cams, the switch-on/switch-off times contradict each other. In this case, cam No3 has priority over cam No2, and cam No2 has priority over cam No1.


Setting the Clock

To enter switching times, proceed as follows:

1. Position the cursor on one of the clock’s No parameters (e.g. No1).

2. Press the OK key.

LOGO! opens the parameter window for the cam. The cursor is positioned on the day of the week.

3. Use the [image] and [image] keys to select one or more days of the week.

4. Use the [image] key to move the cursor to the first position for the switch-on time.

5. Set the switch-on time.
You use the [image] and [image] to change the value.
To move the cursor from one position to another, you use the [image] and [image] keys. You can only select the value --:-- at the first position (--:-- means no switching operation).

6. Set the switch-off time (same procedure as for step 5).

7. Conclude your input by pressing the OK key.

Clock: Examples

You can use the clock to combine switch-on and switch-off times however you like. Here are some examples:

Example 1

The clock’s output is to be switched on every Monday from 08:00 to 13:00 hours:

B01:No1
Day=Mo
On =08:00
Off=13:00

Example 2

The clock’s output is to be switched on every day from 08:00 to 13:00 hours and from 15:00 to 18:30 hours. You need 2 cams for this:

B01:No1
Day=Mo..Su
On =08:00
Off=13:00

B01:No2
Day=Mo..Su
On =15:00
Off=18:30

Example 3

The clock’s output is to be switched on every day from Monday to Saturday from 08:00 to 13:00 hours and from 15:00 to 18:30 hours. In addition, it is also to be switched on on Sunday between 11:00 hours and 15:00 hours. You need 3 cams for this:

B01:No1
Day=Mo..Sa
On =08:00
Off=13:00

B01:No2
Day=Mo..Sa
On =15:00

Latching Relay

Wiring	Description
S input	You set the output (Q) to 1 via the S input (Set).
R input	You reset the output (Q) to 0 via the R input (Reset). If S and R are both 1 at the same time, the output is reset (resetting takes priority).
Par parameter	Par is only available in LOGO!...-L... versions. You can use this parameter to switch remanence on and off. Rem:  off = no remanence on = the state can be stored as a remanent one
Q output	Q switches on when S is sent and remains on until the R input is set.

Switching behavior

A latching relay is a simple binary flip-flop. The value of the output depends on the signals of the inputs and the previous signal of the output. The following table illustrates the logic once more:

S	R	Q	Note
0	0	State remains the same
0	1	0	Reset
1	0	1	Set
1	1	0	Reset (resetting has priority over setting)
State after power on

All LOGO! versions without program module	All LOGO! ...L... versions with red or yellow program module
The latching relay is always reset and the Q output always set to 0 after power on.	If remanence has not been parameterized, the latching relay is reset and the Q output set to 0 after power on.
	If remanence has been parameterized, the state that was current before LOGO! was switched off is set after power on.


Clock Pulse Generator

Wiring	Description
En input	You switch the clock pulse generator on (En=1) and off (En=0) via the En (enable) input.
T parameter	T is the time for which the output is switched on or off.
Q output	Q switches on and off cyclically with the clock time T.

Timing diagram

You use the T parameter to specify how long the on and off times are to last. You use the En (enable) input to switch the clock pulse generator on. The clock pulse generator sets the output to 1 for the time T, then to 0 for the time T, and so on until the En input is at 0.

Note on the T parameter:
Always specify a time for T ≥ 0.10 s an. For T = 0.05 s and T = 0.00 s, the time T is not defined.

See also Tips & Tricks: Clock Pulse Generator

Note on relay outputs:
Relay outputs that switch under load get worn a little with each switching operation. To find out how many switching operations a LOGO! output can execute, refer to the chapter entitled ”Technical data” in the LOGO! manual. Your LOGO! dealer will provide you with a manual.


Retentive On-Delay

Wiring	Description
Trg input	You start the time for the on-delay via the Trg (trigger) input.
R input	You reset the time for the on-delay and set the output to 0 via the R (reset) input (R has priority over Trg).
T parameter	T is the delay time after which the output is switched on (the output changes from 0 to 1).
Q output	Q is switched on after the time T expires.

Timing diagram

If the state of the Trg input changes from 0 to 1, the current time Ta starts. When Ta reaches the time T, the output (Q) is set to 1. Another switching operation at the Trg input has no effect on Ta.

The output and the time Ta are not reset to 0 until the state of the R input changes to 1 again.

After a power failure, the time that has elapsed is reset.


Up and Down Counter

Wiring	Description
R input	You reset the internal count value and the output to zero via the R (Reset) input (R has priority over Cnt).
Cnt input	The counter counts the changes from state 0 to state 1 at the Cnt (Count) input. Changes from state 1 to state 0 are not counted. Maximum count frequency at the input connectors: 5 Hz.
Dir input	You specify the count direction via the Dir (Direction) input: Dir = 0: The counter counts up Dir = 1: The counter counts down
Par parameter	Please read the comments about Par parameter setting that follow this table.
Q output	Q switches on when the count value (Par parameter or Lim; see below) is reached.

Par parameter setting

If the internal count value is greater than or equal to Par (Parameter) or Lim, the output is set. In the event of overrunning or underrunning, the counter stops.

Par can be anything between 0 and 9999.

Lim can be anything between 0 and 999999.

Rem: This parameter can be used in LOGO!...L...  to switch remanence on and off for the internal count value Cnt.

off = no remanence

on = the count value Cnt can be stored as a remanent value

Type of protection:

+: The Par or Lim parameter can be changed during operation.

-: The Par or Lim parameter can only be changed at this point during programming. The parameter(s) cannot be changed during operation.

Timing diagram

At each positive edge at the Cnt input, the internal counter is incremented by one (Dir = 0) or decremented by one (Dir = 1).
If the internal count value is greater than or equal to the value specified for Par (Lim in the case of LOGO! ...L.. versions), the output (Q) is set to 1. You can use the reset input to reset the internal count value to ‘0000’ or ‘000000’. As long as R=1, the output is 0.

After a power failure, the current count value = 0.

Remanence

In LOGO!...L..., it is possible with a number of functions to store switch statuses, times and count values as remanent values. For this to be possible,

•	the values in question must be defined as remanent

•	a yellow or red module must be inserted that permits remanent data storage.

After a power failure, the program continues with those values that were current before the interruption.


Operating Hours Counter

This function is only available in LOGO!...L... versions.

Wiring	Description
R input	R = 0: operating hours counting is possible if Ral is not = 1 R = 1: operating hours counter is stopped You reset the output via the R (Reset) input. The remaining time of the maintenance interval MN is set to MN = MI. The time so far (OT - operating time) is retained.
En input	En is the monitoring input. LOGO! measures the time in which this input is set.
Ral input	Ral = 0: operating hours counting is possible if R is not = 1 Ral = 1: The operating hours counter is stopped You reset the counter and the output via the Ral (Reset all) input. I.e.: the Q output is set to 0  the operating hours measured OT = 0 the remaining time of the maintenance interval (MN) = MI.
Par parameter: MI	MI: preventive maintenance interval specified in hours.  MI can be anything between 0 and 9999 hours.
Q output	If the remaining time MN = 0 (see timing diagram), the output is set.
Par parameter setting

MI is the parameterizable time interval. It can be anything between 0 and 9999.

Type of protection:

+:	The specified monitoring time can be changed during operation.
-:	The specified monitoring time can only be changed at this point during programming. The time cannot be changed during operation.
Timing diagram

MI = parameterizable time interval

MN = remaining time

OT = overall time expired since the last 1 signal at the Ral input

The operating hours counter monitors the En input. As long as this input is 1, LOGO! measures the time expired and the remaining time MN. LOGO! displays the times in Parameterization mode. If the remaining time MN is 0, the Q output is set to 1.

You use reset input R to:	You use reset input Ral to:
reset the Q output set the counter for the remaining time to the specified value MI	reset the Q output set the counter for the remaining time to the specified value MI reset the internal counter OT to 0
The internal counter OT remains unchanged
Limit value for OT

If you reset the operating hours counter by means of the R signal, the operating hours counted in the OT counter are retained. The limit value of the OT counter is 99999 h.

When the operating hours counter reaches this value, no further hours are counted.

Remanence

In LOGO!...L..., the internal count value is always set to remanent. If you want to use this remanence, a yellow or red module must be inserted.

After a power failure, the program recontinues with those values that were current before the interruption.

If a red or yellow module is missing, MN = MI and OT = 0 are set after a power failure.

Application

Monitoring maintenance intervals


Wiping Relay

Wiring	Description
Trg input	You start the time for the wiping relay via the Trg (Trg stands for trigger) input
T parameter	T is the time after which the output is switched off (output signal changes from 1 to 0).
Q output	Q switches on when Trg is sent and remains switched on until T expires.
Timing diagram

When the Trg input takes on the state 1, the Q output switches immediately to state 1. At the same time, the current time Ta starts in LOGO!; the output remains set. When Ta reaches the value set by means of T (Ta=T), the Q output is reset to state 0 (pulse output).

If the Trg input changes from 1 to 0 before the time expires, the output also changes immediately from 1 to 0.


Threshold Switch

This function is only available in LOGO!...-L... versions.

Wiring	Description
Fre input	You apply the input that supplies the pulses to be counted to the Fre input. Use  • input I12 for rapid counts (24 V inputs): max. 150 Hz • any other input or circuit section for low counting frequencies.
Par parameter:  SW↑ SW↓ G_T	SW↑: Switch-on threshold SW↓: Switch-off threshold G_T: Time interval in which the pulses applied are measured.
Q output	Q switches on or off depending on SW↑ and SW↓ (see description below).
Par parameter setting

SW↑ is the switch-on threshold. It can be anything between 0000 and 9999.

SW↓ is the switch-off threshold. It can be anything between 0000 and 9999.

G_T is the time interval in which the pulses applied to Fre are measured. G_T can be anything between 00.05s and 99.95s.

Type of protection:

+:	The definable switching thresholds can be changed during operation.
-:	The definable switching thresholds can only be changed at this point during programming. The thresholds cannot be changed during operation.
Timing diagram

The threshold switch measures the signals at the Fre input. The pulses are measured during a parameterizable period G_T. If the values measured within the time G_T are greater than the switch-on and switch-off thresholds, the Q output switches on.

Q switches off again when the number of pulses measured has reached or fallen below the value of the switch-off threshold.


Blocks (BN)

Whenever you insert a block in a program, LOGO! gives this block a number, the block number. The block number appears at the top right of the display.

LOGO! uses the block numbers to indicate the connections between blocks:

To move the cursor to a block in the program, proceed as follows:

Position the cursor on a block input at which there is a block number (in the diagram, you position the cursor on the second input of block B01), and press the [image] key. The cursor jumps to the block whose block number this is (block B03 in the diagram).

There is one more advantage of the block numbers: You can connect any block to an input of the current block by means of its block number. In this way, you can use the interim results of logic or other operations more than once. This saves you the work required to enter things again, as well as memory space in LOGO!, and your circuit remains clear and easier to understand.

You can enter a maximum of 30 different blocks in your program. Blocks used a number of times are counted only once.


Memory Requirements and Limitations on Program Size

A program (or, if you prefer, circuit) is subject to limitations as regards its size:

•	The number of blocks connected in series

•	The memory available

Number of blocks connected in series
You can insert up to 7 blocks between an output and an input.

Memory
The function blocks in your program require memory in LOGO!. The table gives you an overview of how much memory each function block occupies in each memory area:

Function block	Par	RAM	Timer	REM
Basic functions	0	0	0	0
On-delay	1	1	1	0
Off-delay	2	1	1	0
Pulse relay	0	1	0	1
Clock	6	2	0	0
Latching relay	0	1	0	1
Clock pulse generator	1	1	1	0
Retentive on-delay	2	1	1	0
Counter	2	2	0	2
Wiping relay	1	1	1	0
Operating hours counter	2	0	0	4
Threshold switch	3	3	1	0

The maximum amount of memory a program can occupy in LOGO! is as follows:

Par:	up to 27
RAM:	up to 24
Timer:	up to 10

REM:	up to 7
Blocks:	up to 30 different blocs per program

Example:

A program contains:

Function block	Par	RAM	Timer	REM	Blocks
2 on-delays	2	2	2	0	2
2 off-delays	4	2	2	0	2
1 clock	6	2	0	0	1
1 clock pulse generator	1	1	1	0	1
1 counter	2	2	0	(2)	1
10 basic functions (AND, OR, ...)	0	0	0	0	10
Memory areas occupied by the program	15	9	5	(2)	17
Maximum available in LOGO!:	27	24	10	7	30
Still available in LOGO!	12	15	5	(5)	13
So the program fits in LOGO!.
The following is displayed in LOGO!Soft’s status line:
The number of blocks, parameters, RAM, timers and REM still available, and
the maximum number of blocks, parameters RAM, times and for REM (remanence)

If you cannot enter any more blocks when entering a program, this means that a memory area is full. LOGO! offers you only those blocks for which it still has enough space. If there is not enough space in LOGO! for any of the blocks in the list, you can no longer select the list.

When a memory area is full, optimize your circuit or use a second LOGO! module.

Warning: Important Information

Warning for LOGO 230... :

Dangerous voltage!

Do not put your finger or any object or tool in the shaft for the program module/card. If the power supply is not connected correctly, the plug for the program module/card may carry voltage.

What to do:

Connect L1 only to a single phase and N only to the neutral conductor. Connect the inputs to the same phase as the power supply.

In order to comply with DIN VDE 0631, note the following:

•	LOGO! standard version: Connect the inputs to the same phase as the power supply.

•	LOGO! ..L versions: Connect the inputs of each block of 4 to the same phase (I1 to I4; I5 to I8; I9 to I12).

The shaft for the program module/card must always be closed during operation. If there is no program module in the shaft, the cover must be on it.

Tips & Tricks: Clock Pulse Generator

If you set a time of T = 0 for the clock pulse generator, LOGO! works with the smallest possible time. This time depends on how big the program is.

Here is our tip:

By setting T=0 you can determine how long it takes LOGO! to run the program:

1.	Connect the output of the clock pulse generator to a counter, and count the number of pulses within a specific time period (e.g. 10 seconds). You can see the number of pulses in parameterization mode, where LOGO! displays the current counter value.

2.	Divide the time by the number of pulses to obtain the program’s run time.

(You will be amazed how fast LOGO! is!)

It’s even easier if you use a counter that counts a specific number of pulses for you. Here is a possible circuit:

You can reset the counter via I1 (connected to the R (reset) input).
We count the pulses of the clock pulse generator at the Cnt input of the counter. The clock pulse generator runs continuously because we have switched its input to hi (hi = 1). We have selected a value for the T parameter of the clock pulse generator such that the clock pulse generator works as quickly as possible.
The counter always counts forwards (i.e. from 0000 to 9999), since Dir is on lo (lo = 0).
The output of the counter is set at 1000 pulses. You can reset the counter and the output via the reset input (connected here to I1).
Use a stop clock to measure the time from the beginning of counting (I1: 1→0) to the point when 1000 pulses are counted (Q1: 0→1). Divide this time by 2000 to obtain the time LOGO! requires for a program run.


Tips & Tricks: Deleting a Block

To delete a block, proceed as follows:

1.	Position the cursor at the input of the block to which the block you want to delete is connected. For example, if block B02 is connected to the input of block B01, move the cursor to block B01. B02 is at one input. Position the cursor on the B of B02.

2.	Press the OK key.

3.	Select the Co list, and press the OK key.

4.	x is then displayed. Press the OK key to confirm.

Result:

Block B02 is deleted, together with everything connected to it. If block B02 occurs again in your program, only the connection to block B01 is deleted.

Exercise caution when deleting blocks that are used more than once.

If you use several interconnected blocks more than once in a program, and you delete a block from this series of blocks, the following applies:

When you delete the first block in the series (the one nearest the output), this has no effect on the other parts of the circuit where you use this series of blocks.

When you delete another block in the series, the block is deleted from all parts of the circuit in which this series of blocks is used.


Tips & Tricks: Replacing a Block

You can normally only replace a block with a block that has a similar function and the same number of inputs. To insert a completely different block in the program, proceed as follows:

1.	Delete the block (see Tips & Tricks: Deleting a Block).

2.	Insert the new block at the same position.


Tips & Tricks: Moving Part of a Circuit

To move a block and the part of the circuit connected to the input of the block to another position in the circuit, proceed as follows:

1.	Position the cursor at the input of the block to which you want the part of the circuit to be connected.

2.	Press the OK key.

3.	Select the BN list with the [image] or [image] key, and press OK.

4.	Select the block to which the part of the circuit is connected, and press the OK key.

5.	Delete the block at its original position (see Tips & Tricks: Deleting a Block).


Tips & Tricks: Power Failure While LOGO! Is Copying

If there is a power failure while you are copying something to the program module, you have to start the copy operation again. We have incorporated some special mechanisms to ensure that this works:

When copying from LOGO! to the program module/card:

At the beginning of the copy operation, LOGO! marks the program as invalid. When copying is completed, LOGO! resets the marking, thus making the program valid again.

If there is a power failure during copying, LOGO! recognizes at power on that the program on the program module/card is invalid and uses the program that is still stored in LOGO!. You can now copy this program to the program module/card again.

When copying from the program module/card to LOGO!:

If there is a power failure during copying, LOGO! copies the program from the program module/card automatically on restoration of the power supply.


Tips & Tricks: Setting Time for Automatic Redrawing

The block diagram is automatically redrawn when you make a change to the view you have selected. The default setting for the delay (wait time) before this redrawing takes place is approximately 0.8 s.

If you find this delay too long or too short, you can change the above default setting by making an entry in the LOGOSOFT.INI file.

Before you make any changes, make a backup copy of LOGOSOFT.INI first.

Then change the value for RedrawWaittime in the [LOGO!_V20] section to the value you want.


Deleting a Program Module (Card)

You have to begin by backing up the program in LOGO! on a program module (card) so as not to lose it. Only then can you delete another program module (card).

To delete a program module (card), proceed as follows:

1.	Delete the program in LOGO! with Program, Clear Prg.

2.	Copy the deleted program to the program module (card) with PC/Card, LOGO→Card.

The program module (card) is deleted.

You can now copy the saved program to LOGO! again.

AS Interface

This help will be of interest to you if you want to connect LOGO!..LB11 to the ASi bus.

LOGO!...LB11 can be integrated into a network as an ASi slave. Using a two-wire lead, you can then

•	read in and process 4 additional inputs via the ASi bus

•	operate 4 additional outputs one one overlaid master of the ASi bus

You configure LOGO!...LB11 in the ASi bus by means of the ASi master you are using.

Requirements for operating LOGO! ...LB11 on an ASi master

Please note: LOGO!...LB11 must be registered in the ASi bus , i.e. LOGO! is assigned an address by the bus master.

Caution

The ASi address can be changed at least 10 times for all LOGO! ...LB11 versions. We cannot guarantee further changes made.

Bus Connector

Always use the standard bus connector enclosed in the packaging to connect LOGO!.


Connecting the ASi Bus

Connect the bus connector cable to an approved connector in the system, making sure that the polarity is correct.

Then push the wired connector into the interface marked AS interface.


LOGO!...LB11 on the ASi Bus

LOGO!...LB11 must be known to the bus master if you are to be able to use the ASi functionality. This takes place automatically when you connect LOGO!...LB11 to the bus lead. The master detects the address of the slave.

In the case of LOGO!...LB11, the address preset at the factory = 0. Address changes are carried out by means of a special addressing device or your ASi master.

If there are several slaves with an address of 0 on the bus, you can switch LOGO! to passive on the ASi bus

If there are no address conflicts in the system or if only one slave with the address 0 is connected, you do not have to take any further steps.


Active-Passive Switchover

All LOGO!...LB11 versions are factory-set to address 0.

When the master is assigning addresses, only one active slave may be set to address 0 on the ASi bus at any one time. All other slaves with the address 0 must be passive, that is, unknown on the bus.

To switch LOGO!...LB11  to passive , we have built a specific menu item into the programming menu.


Switching LOGO! ...LB11 Between Active and Passive

1.	Switch LOGO!...LB11 to programming mode (using the 3-finger combination) and press OK to go directly into the programming menu.

2.	Press the [image] key 3 times.
The cursor (>) is now positioned at the start of the ASi_Bus.. line.

3.	Press OK. The following display appears:

4.	Switch LOGO!...LB11 to passive by pressing the [image] key and then OK. The new state is then displayed:

5.	As soon as the master has detected an active slave and assigned it an address, you can switch another slave back from passive to active.

You can exit the menu for switching back and forth between active and passive only if LOGO! is switched active.

Diagram

The size in which the diagram is displayed depends on the number of lines.

You can display the diagram for the circuit at one or more outputs.


Program Module

This is the program module. Remember that either the program module or the cover must always be inserted in the shaft to prevent anybody putting an object or a finger in it. You insert the program module, the cover or the connector of the LOGO! PC cable in the shaft.


Wiring

We have indicated here the principles according to which LOGO! is wired.


AS Interface

You connect the ASi bus to LOGO! ...LB11 by means of the connector supplied with LOGO.

Make sure that the polarity is correct when connecting the bus.


REM

REM stands for remanence. With a number of special functions in LOGO! ...L..., the current parameters are stored when the power is switched off. The status line then shows you how many parameters are still free for special functions and the maximum number of parameters for which there is space in LOGO!.

Remanence is only possible in connection with a red or yellow program module.

The following special functions offer remanence:

•	Pulse relay (remanence can be switched off)

•	Latching relay (remanence can be switched off)

•	Counters (remanence can be switched off)

•	Operating hours counter

•	Threshold switch

Note:

Remanence is not simulated in LOGO!Soft.


Request Version Number

This opens a window in which you can select a LOGO! version.

LOGO!Soft adapts the functional scope to match the version you have selected. This means that only those functions actually possible are made available in programming mode.

3-Finger Combination in LOGO!Soft

While working with LOGO!, you have got to know the 3-finger combination with which you switch LOGO! to programming mode.

Please read the section entitled: The Golden Rules for Working With LOGO!

This key combination can also be used in LOGO!Soft:

In LOGO!Soft, the combination of keys used is Ctrl+Alt+↵

3-finger combination while entering a program

If you are making changes to an existing or a new program, the following rules apply:

If you have not yet finished entering the program:	If you have finished entering the program:
The changes are discarded after you have replied to a prompt. LOGO!Soft switches to the main menu.	LOGO!Soft switches to the main menu. The modified program is stored in LOGO!Soft.


LOGO! Type

LOGO! 230RLB11: The current version has an AS interface connnection.

LOGO! 230RCL: The current version does not have an AS interface connection.


"Help" Help

There are visible links at many points in this image.

You can obtain help information on a section of the image when the mouse pointer turns into a hand. Press the left mouse button to get this information.

This type of access to help information is available at a number of other points in the LOGO!Soft help system. To see whether information is available, simply move the mouse slowly over an image.


RAM or REM

Depending on wether the function is parameterized with or without remanence, the memory space is assigned as follows (in the case of LOGO! ...L.. versions only):

The function block occupies RAM when remanence is switched off.

The function block occupies REM when remanence is switched on.


ASi_Bus.. Menu Line
ASi_Bus.. Menu Bar

This is only displayed in the case of LOGO! ...LB11 versions (AS interface).


ASi Address and ASi Profile in LOGO! ...LB11 Versions

•	Default address = 0

•	ASi profile = 7.F (I/O config = 7; ID code = F)


Output Is Switched On

A green display at the output indicates that it is switched on.


Availability of the ASi_Bus.. Menu Option

This menu option is only available in LOGO! ...LB11 versions.


Help Texts in the Status Line

In many cases, LOGO!Soft displays brief information on the right-hand side of the status line.


Changed Program

An asterisk after the file name in the window header indicates that the current program has been changed and not yet saved.


Current Output

Q2 is the current output you were editing when you called the overview diagram.


3-Finger Combination

You use the 3-finger key combination to switch LOGO! to programming mode.

Press the left, right and OK keys simultaneously.

In programming mode, LOGO! does not execute the program. The outputs are switched off.


Programming Mode

You program LOGO! in programming mode.

LOGO! does not execute the program in programming mode.

The outputs are switched off (they have the state '0').

Only electricians trained to do so should use programming mode.


Time (T)

Time that elapses before a response at the output is executed after a signal change at the input. You enter the time at the parameter input T.

You can enter the following for T:

Seconds: 00.00s to 99.95s (in steps of 00.05 second)
Minutes: 00:00m to 99:59m (in steps of 00.01 minute)
Hours: 00:00h to 99:59h (in steps of 00.01 hour)


2-Finger Combination

You use the 2-finger key combination to switch LOGO! to parameterization mode.
