LOGO! Manual

A5E00380835-01

Getting started with LOGO!

Which communication modules are available?

LOGO! communication module (CM) AS interface, that is described in more detail in a separate documentation.

The communication module has four virtual inputs and outputs, and acts as an interface between an

AS-Interface system and a LOGO! system. The module enables four data bits to be transferred from the

LOGO! Basic to the AS-Interface system and vice versa.

LOGO! communication module (CM) EIB/KNX, that is described in more detail in a separate documentation.

CM EIB/KNX is a communication module (CM) for connecting the LOGO! to the

EIB

. It is implemented as a slave module for the logic module LOGO! (12/24 or

115/240 V).

The CM EIB/KNX is a bus device on the

EIB

and enables the LOGO! to communicate with other EIB devices through the exchange of EIB data points.

It transfers EIB data points to the LOGO! and LOGO!

functions to the

EIB

.

CM EIB/KNX makes the current states of the configured

EIB data points available to the LOGO! so that it is able to link them with its logic functions and timing elements.

The EIB data points can thus also be linked with those of the local LOGO! inputs and outputs. The CM

EIB/KNX then transfers each change in the status of the output signals on the

EIB

.

The combination of the LOGO! and CM EIB/KNX provides the user with a distributed controller functionality for the EIB with the possibility of carrying out settings or modifying parameters or logic operations quickly, simply and without a programming device.

It’s your choice

The various LOGO! Basic versions, expansion modules and communication modules offer you a highly flexible and adaptive system to suit your specific tasks.

LOGO! Manual

A5E00380835-01

Getting started with LOGO!

The LOGO! system offers you many solutions such as for small domestic installations, simple automation tasks, and even complex engineering tasks involving its integration into a bus system (e.g. communication module AS interface).

Note

LOGO! Basic may only be equipped with expansion modules of the same voltage class. Mechanical encoding pins in the housing prevent you from connecting devices of a different voltage class.

Exception: The left-hand interface of an analog module or communication module is galvanically isolated.

This type of expansion module can therefore be connected to devices of a different voltage class.

See also Chapter 2.1.

Each LOGO! Basic provides the following connections for the creation of the circuit program, regardless of the number of connected modules:

Digital inputs I1 to I24

Analog inputs AI1 to AI8

Digital outputs Q1 to Q16

Analog outputs AQ1 and AQ2

Digital flag blocks M1 to M24, M8: Startup flag

Analog flag blocks AM1 to AM6

Shift register bits S1 to S8

4 cursor keys

16 blank outputs X1 to X16.

2 LOGO! installation and wiring

General guidelines

Please note the following guidelines for installing and wiring your LOGO! :

Always ensure that the wiring of your LOGO! is compliant with current rules and standards. Also, conform with all national and regional regulations when you install and operate the devices. For information on standards and regulations that apply to your specific case, contact your local authorities.

Make sure that the device is de-energised.

Always use cables with appropriate conductor cross-sections for the relevant current. You can wire the

LOGO! with cable conductor cross-sections from

1.5 mm

2

to 2.5 mm

2

; see Chapter 2.3.

Only use approved bus cables.

Do not exceed the screw torque of the terminals. The maximum torque is: 0.5 N/m, see Chapter 2.3.

Keep the cabling as short as possible. If longer cables are necessary, you should use shielded versions. You should always route your cables in pairs: i.e. one neutral conductor plus one phase conductor or signal line.

Always keep separate:

– The AC wiring

– High-voltage DC circuits with high-frequency switching cycles

– Low-voltage signal wiring.

– The EIB bus cable may also be laid in parallel to other cables.

Ensure that the wires are installed with appropriate strain relief.

Provide a suitable lightning surge arrester for cables installed in hazardous areas.

LOGO! Manual

A5E00380835-01

15

LOGO! installation and wiring

Do not connect an external power supply in parallel to the output load of a DC output. This could develop a reverse current at the output if you have not installed a diode or similar barrier device.

The CM EIB/KNX must have its own power supply

(24 V).

Reliable functioning of the equipment is only ensured with certified components!

Note

LOGO! units may only be installed and wired by skilled personnel who are familiar with and follow general engineering rules and relevant regulations and standards.

What you must note when installing

LOGO! is designed for fixed and enclosed installation in the housing or the control cabinet.

!

Warning

Open facilities

Death, serious bodily injury or considerable damage to property can occur.

Modules of a LOGO! are open facilities. This means you must install LOGO! only in a housing or cabinet.

Access to the housings or cabinets must only be possible by using a key or a tool and only authorized or approved personnel may be allowed access.

It is permissible to operate LOGO! from its front at any time.

Safety of electronic control equipment

Introduction

The notes below apply regardless of the type or manufacturer of the electronic control.

Reliability

Maximum reliability of LOGO! devices and components is achieved by implementing extensive and cost-effective measures during development and manufacture.

This includes the following:

Use of high-quality components;

Worst-case design of all circuits;

Systematic and computer-aided testing of all components;

Burn-in of all large-scale integrated circuits (e.g.

processors, memory, etc.);

Measures preventing static charge when handling MOS

ICs;

Visual checks at different stages of manufacture;

Continuous heat-run test at elevated ambient temperature over a period of several days;

Careful computer-controlled final testing;

Statistical evaluation of all returned systems and components to enable the immediate initiation of suitable corrective measures;

Monitoring of major control components, using on-line tests (cyclic interrupt for the CPU, etc.).

These measures are referred to as basic measures.

Carrying out tests

You must, however, ensure safety in your plant.

Before finally commissioning a system you should carry out complete functional testing as well as all necessary safety testing.

Also include in testing any predictable faults that can occur.

This means that you will avoid any danger to the plant or to people in it during operation.

LOGO! Manual

A5E00380835-01

17

LOGO! installation and wiring

Risks

In all cases where the occurrence of failures can result in material damage or injury to persons, special measures must be taken to enhance the safety of the installation and therefore also of the situation. System-specific and special regulations exist for such applications. They must be observed on installing the control system (e.g. VDE

0116 for burner control systems).

For electronic control equipment with a safety function, the measures that have to be taken to prevent or rectify faults are based on the risks involved in the installation. As of a certain degree of hazard the basic measures mentioned above are no longer sufficient. Additional measures must be implemented and approved for the controller.

Important information

The instructions in the operating manual must be followed exactly. Incorrect handling can render measures intended to prevent dangerous faults ineffective, or generate additional sources of danger.

High-speed/optimal communication performance

For optimal and high-speed communication performance between LOGO! Basic and the various modules, we recommend you install the “digital modules first, then the analog modules” (example above).

We recommend that you position the CM AS Interface on the far right-hand side. (If the AS Interface voltage fails, communication between the LOGO! system and the expansion modules, which are arranged to the right of the LOGO!

CM AS Interface expansion module, is interrupted.)

LOGO! Manual

A5E00380835-01

19

LOGO! installation and wiring

Note

The digital inputs of LOGO! 230 RC/RCo and of expansion module DM16 230R are divided into two groups, each consisting of four inputs.

Within

the same group, all inputs must be operated on the

same

phase.

Different

phases are only possible

between

the groups.

Example: I1 to I4 on phase

L1

, I5 to I8 on phase

L2

.

Inputs within the LOGO! DM8 230R may

not

be connected to different phases.

Sensor connections

Connecting glow lamps and 2-wire proximity switches

(Bero) to LOGO! 230 RC/230 RCo or LOGO! DM8 230 R

(AC) and LOGO! DM16 230R (AC)

The figure below shows how you connect a switch with a glow lamp to the LOGO! The current that flows through the glow lamp allows LOGO! to detect a ”1” signal even though the switch contact is not closed. If, however, you use a switch whose glow lamp is fitted with a power supply, this response does not occur.

LOGO! Manual

A5E00380835-01

33

LOGO! installation and wiring

Take the quiescent current of any 2-wire proximity switches used into account. The level of the quiescent current of some 2-wire proximity switches is high enough to trigger a logical ”1” signal at the LOGO! input. You should therefore compare the quiescent current of the proximity switches with the technical data of inputs Appendix A.

Remedy

To suppress this response, use Siemens components with the following order number: Capacitor 3SB 1420–3D. As an alternative, you can also use an X capacitor rated at 100 nF and 2.5 kV. In a destructive situation, this type of capacitor safely disconnects. You must choose the voltage level for which the capacitor is rated such that it is not destroyed in the case of overvoltage!

At 230 V AC, the voltage between N and an input I(n) must not be greater than 40 V to guarantee a ”0” signal. You can connect approximately ten glow lamps to the capacitor.

Restrictions

Signal status transitions 0 !

1 / 1 !

0

After a 0 to 1 or 1 to 0 transition, the signal must remain constant at the input at least for the duration of one program cycle, so that LOGO! can detect the new signal status.

The program execution time is determined by the size of the circuit program. Appendix B contains a benchmark test routine that you can use to determine the current scan cycle time.

Special features of LOGO! 12/24 RC/RCo and LOGO! 24/24o

High-speed inputs: I5 and I6

These versions are also equipped with high-speed counting inputs (Up/down counters, Threshold triggers). The restrictions mentioned earlier do not apply to these high-speed inputs.

34

LOGO! Manual

A5E00380835-01

LOGO! installation and wiring

Note

The high-speed inputs I5 and I6 are the same as in the previous versions 0BA0 to 0BA4, i.e. a circuit program that is written in these versions can be transferred to the new

0BA5 units by means of the programming software LOGO!

SoftComfort, without any changes to these features. In contrast to this, you need to modify circuit programs written for a LOGO!...L version (high-speed inputs I11/I12).

Expansion modules do not have high-speed inputs.

Analog inputs: I7 and I8

The inputs I7 and I8 of LOGO! versions 12/24RC/RCo and

24/24o can be used both as standard digital inputs and as analog inputs. The input mode is defined in the LOGO!

circuit program.

The inputs I7 / I8 provide digital functions, and the inputs

AI1 and AI2 provide analog functions.

See also Chapter 4.1.

When using inputs I7 and I8 as analog ones, only the range from 0 to 10 V DC is available.

Connecting a potentiometer to inputs I7 / I8

To allow you to achieve 10 V as the maximum value when you completely turn the potentiometer once, you must connect a series resistor on the potentiometer’s input side regardless of the input voltage.

We suggest the following sizes of potentiometers and associated series resistors:

Voltage

12 V

24 V

Potentiometer Series Resistor

5 k

W

5 k W

6,6 k W

LOGO! Manual

A5E00380835-01

35

LOGO! installation and wiring

When using a potentiometer and 10 V input voltage as the maximum value, you must ensure that with a connected input voltage of 24 V, 14 V must release via the series resistor so that a maximum of 10 V are supplied when you turn the potentiometer one full rotation. With a voltage of 12 V, this can be neglected.

Note

The LOGO! AM 2 expansion module provides further analog inputs. The LOGO! AM 2 PT100 expansion module provides Pt100 inputs.

Always use twisted and shielded cables for analog signals, and keep these as short as possible.

Connecting a two-wire sensor to the LOGO! AM 2

Wire up the two-wire sensor’s connecting wires as follows:

1. Connect the minus connector on the sensor to connector I1 on the analog expansion module.

2. Connect the plus connector on the sensor to the 24 V supply voltage (L+).

3. Connect the ground connector of the supply voltage to connector M1 on the analog expansion module.

LOGO! AM 2 PT100

You can connect either a 2- or 3-wire Pt100 resistive thermocouple to the module.

For a

2-wire

connection, you need to short-circuit terminals

M1+ and IC1 or M2+ and IC2. Errors caused by the ohmic resistance of the measuring line are not compensated with this type of connection. A line resistance of 1 W is proportional to a measuring error of +2.5

Note

Fluctuating analog values are due to screening on the connecting wire from the analog valuator device to the analog

AM 2 / AM 2 PT100 LOGO! expansion module (encoder wire) that has either been mounted incorrectly or not at all.

To avoid fluctuating analog values when using these expansion modules, proceed as follows:

Use only shielded encoder wires.

Shorten the encoder wire as much as possible. The encoder wire must not be more than 10 meters long.

Clamp the encoder wire on one side only and clamp it only to the PE terminal on the AM 2 / AM 2 PT100 expansion module.

Connect ground on the encoder supply to the PE terminal on the expansion module.

Avoid operating the LOGO! AM 2 PT100 expansion module on a power supply that is not grounded (potential–free). If you cannot avoid this, connect the negative output/ground output on the power supply to the shielding on the resistance thermometer’s measuring wires.

The CM EIB/KNX takes over the communication between the LOGO! and

EIB

and makes communication available via

EIB

inputs/outputs.

The application of the CM EIB/KNX fills the complete

LOGO! process image; i.e. inputs or outputs which are not occupied on the LOGO! can be occupied via the EIB.

Note

For detailed information about the networking of LOGO! on the

EIB

bus please refer to the LOGO! CM EIB/KNX documentation, in particular the Micro Automation Set 8.

2.3.5 Connecting the AS interface bus

You can set the address on the AS interface bus before or after installation.

If the module is addressed via the address socket in the installed condition, the AS-Interface voltage must be disconnected beforehand. This is necessary for safety reasons.

Networking on the AS interface bus

To make the connection to the AS interface bus, you need a communications-capable LOGO! variant:

LOGO! basic module + CM AS-I.

To be able to send data across the AS interface bus to the

LOGO! and to receive data from it in the same way, you also need an AS interface power supply and an AS interface master (e.g. an S7-200 with a

CP243-2).

LOGO! can only be accepted as a slave on the AS interface bus. This means that it is not possible to directly exchange data between two LOGO! devices. Data is always exchanged across the AS interface master.

!

Warning

The AS-Interface and LOGO! systems must

never

be connected together electrically!

Use safe isolation acc. to IEC 61131–2, EN

2.4 Putting into operation

2.4.1 Switching on the LOGO!/Power On

LOGO! does not have a power switch. The reaction of

LOGO! during startup depends on

Whether a circuit program is stored in LOGO!

Whether a program module (Card) is inserted

Whether this is a LOGO! version without display unit

(LOGO!...o)

The status of LOGO! at the time of power failure.

All possible reaction of LOGO! are described on the following page.

To ensure that the expansion module on the LOGO!

changes to RUN mode, check the following:

Has the sliding contact between the LOGO! and the expansion module snapped into place properly?

Is the power supply connected to the expansion module?

In addition, always ensure that you switch on the power supply to the expansion module first before activating the power supply to the LOGO! basic module (or activate both power supplies at the same time); if you do not do this, the system does not detect the expansion module when you start up the LOGO! basic module.

LOGO! installation and wiring

You can also memorize four simple rules for starting

LOGO! :

1. If neither the LOGO! nor the inserted program module

(Card) contains a circuit program, the LOGO! (with display unit ) reports: ’No Program / Press ESC’.

2. A circuit program on the program module (Card) is automatically copied to LOGO!. The circuit program in the LOGO! is overwritten.

3. If there is a circuit program in LOGO! or on the program module (Card), LOGO! adopts the operational state it had prior to POWER-OFF. Versions without display unit

(LOGO!...o) automatically change from STOP to RUN

(LED changes from red to green).

4. If you have enabled retentivity at least for one function, or a function is permanently retentive, the current values are retained at POWER-OFF.

Note

When a power failure occurs while you are entering a circuit program, the program in LOGO! will be deleted after power is returned.

Before you modify the circuit program, you should therefore save a backup copy of your original to a program module (Card) or to a computer (LOGO!Soft Comfort).

2. Connect the PC to the serial EIB interface.

3. Start software ETS, using ETS2 version 1.2.

4. Configure the application program in ETS2, V 1.2.

5. The application program is loaded into the devices via the EIB interface. The application program is available on the LOGO! home page (http://www.siemens.de/logo).

6. Click on ”Program Physical Address” in ETS.

7. Press the button of the CM EIB/KNX to switch the CM

EIB/KNX to programming mode; LED lights up orange.

Note

The button “Prog

” should not be pressed too firmly.

If the bus connection is OK, the LED lights up green.

In programming mode, the LED lights up orange.

8. If the LED is extinguished, the programming of the physical address has finished. You can now mark the physical address on the device. Composition of the physical address:

Area / Line / Device XX / XX / XXX

9. The application program can now be run. The device is then ready for operation.

10.If several CM EIB/KNX are installed in an EIB system, steps 1 to 9 must be repeated for each CM EIB/KNX.

11.Any further details about EIB commissioning can be found in the corresponding documentation.

3 Programming LOGO!

Getting started with LOGO!

Programming in our context refers to creating a circuit program. A LOGO! circuit program program is actually nothing more than a circuit diagram presented in a slightly different form!

We have adapted this presentation to the LOGO! display field. In this chapter we are going to show you how to use

LOGO! to create the LOGO! circuit programs for your application.

At this point, we once again refer to LOGO!Soft Comfort, which is the LOGO! programming software you can use to quickly and easily create, test, modify save and print the circuit programs. The topics in this manual relate only to the creation of circuit programs on the actual LOGO!, because the programming software LOGO!Soft Comfort already contains extensive Online Help.

See also Chapter 7.

Note

LOGO! versions without display unit, i.e. the LOGO! 24o,

LOGO! 12/24RCo, LOGO! 24RCo and LOGO! 230RCo units, do not have an operator panel and display unit. They are primarily designed for use in small machine and process equipment engineering systems for series production.

LOGO!...o versions are not programmed directly on the unit. Instead, the circuit program is downloaded to this device by means of LOGO!Soft Comfort or program modules

(Cards) of other LOGO! 0BA5 units.

LOGO! versions without a display can not write data to program modules (Cards).

See Chapters 6, 7 and Appendix C.

Programming LOGO!

A small example in the first part of this chapter introduces the operating principle of LOGO!.

We shall first show you the meaning of two basic terms, namely the

connector

and the

block

.

As the next step, we shall create a circuit program based on a simple conventional circuit, which you ...

can enter directly in LOGO! in the third step.

It will take you only a few pages of this manual store your first executable circuit program in the LOGO! unit. With a suitable hardware (switches etc.), you will then be able to carry out first tests.

Programming LOGO!

Note

LOGO! can recognize, read and switch the I/O of all expansion modules regardless of their type. The I/Os are presented in the installation order of the modules.

The following I/Os and flag blocks are available for creating your circuit program: : I1 to I24, AI1 to AI8, Q1 to

Q16, AQ1 and AQ2, M1 to M24 and AM1 to AM6. Also available are the shift register bits S1 to S8, 4 cursor keys

C , C , C and C , as well as 16 blank outputs X1 to

X16. More details are found in Chapter 4.1.

The following applies to inputs I7 and I8 of LOGO! 12/24...

and LOGO! 24/24o versions: If Ix is used in the circuit program, this input signal is digital; signals at AIx are analog.

Input AIx can only represent the connector that is actually capable of handling analog signals.

LOGO!’s connectors

The term connector refers to all connections and states in

LOGO! .

The digital I/O status can be ’0’ or ’1’. Status ’0’ means that the input does not carry a voltage. Status ’1’ means that the input carries voltage.

We have introduced ’hi’, ’lo’ and ’x’ connectors to make it easier for you to create the circuit program:

’hi’ (high) is assigned the status ’1’,

’lo’ (low) is assigned the status ’0’.

You do not have to use all the of connectors of a block. The circuit program automatically assigns the unused connectors a status that ensures proper functioning of the relevant block. If you prefer to do so, you can identify unused connectors with an ’x’.

For information on the meaning of the term “block”, refer to

Chapter 3.3.

3.2 EIB inputs/outputs

The application program “20 CO LOGO! 900E02” controls the communication between the LOGO! and the EIB/KNX bus via the communication module CM EIB/KNX.

By configuring the application program in ETS (EIB Tool

Software), the division of the input and output area of the

LOGO! can be defined as a “hardware channel” and as a

“virtual channel” on the EIB/KNX bus.

This characteristic also applies for analog processing.

A communication object is assigned to each “virtual channel“ of the LOGO! module.

The real-time clock of the LOGO! can be used as a master or slave via the EIB/KNX bus.

The behaviour of the communication objects of the communication module CM EIB/KNX, when the status of the EIB/KNX bus changes, can also be parameterised.

A “virtual input channel“ can be used as a bus state, i.e. a bus voltage failure can be reported.

Functions of the application program

Specification of the hardware configuration (number of local digital inputs and outputs, analog inputs)

Selection of time master or slave

Use of I24 as a bus status signal

Behaviour on bus voltage failure/recovery

Input type as monoflop/normal for digital inputs via the

EIB/KNX

Output type as normal/dimmer/edge evaluation for digital outputs via the EIB/KNX

Data type, adaptation, cyclical sending and sending on change in value for analog outputs via the EIB/KNX and analog inputs on the LOGO!

Any further details about configuring the application program in ETS can be found in the current application program description.

3.3 Blocks and block numbers

This chapter shows you how to use LOGO! elements to create complex circuits and how blocks and I/O are interconnected.

In Chapter 3.4 we are going to show you how to transform a conventional circuit to obtain a LOGO! circuit program.

Blocks

A block in LOGO! represents a function that is used to convert input information into output information. Previously you had to wire the individual elements in a control cabinet or terminal box.

When you create the circuit program, you interconnect the blocks. To do so, simply select the connection you require from the

Co

menu The menu name Co is an abbreviation of the term “Connector”.

Logic operations

The most elementary blocks are the logic operations:

AND

OR

...

I1

I2 x x

1

Q

Inputs I1 and I2 are here connected to the OR block. The last two inputs of the block remain unused and are identified by the creator of the circuit program with an ’x’.

These special functions offer you significantly higher performance:

Pulse relay

Up/down counter

On-delay

Softkey

....

In Chapter 4 you will find a full list of the LOGO! functions.

View of blocks on the LOGO! display

The figure below shows a typical view of the LOGO! display. As you can see, it can show only one block at a time.

We have therefore introduced block numbers to help you check the circuit structure.

Programming LOGO!

The figure above shows you three views of the LOGO! display, which represent the circuit program. As you can see,

LOGO! interconnects the blocks using their numbers.

Advantages of block numbers

You can connect almost any block to an input of the current block by means of its block number. In this way, you can reuse the interim results of logical or other operations, reduce programming effort, save memory space and clean up your circuit layout. To do so, however, you need to know how LOGO! has named the blocks.

Note

We advise you to create an organizational program chart.

You will find this a valuable aid when you create the circuit program because you can enter all the block numbers that

LOGO! assigns in this chart.

By using the LOGO!Soft Comfort software to program the

LOGO!, you can directly create a function chart of your circuit program. LOGO!Soft Comfort also allows you to assign eight-character names to up to 64 blocks, and to view these on the LOGO! display in parameter assignment mode (see Chapter 3.5).

63

Programming LOGO!

Note

Although you have four inputs available for logic operations (Basic functions, see Chapter 4.2), most of the views will only show three inputs for reasons of clarity. You program this fourth input and assign parameters just like you do with the other three inputs.

To create a circuit logic in LOGO!, start at the output.

The output is the load or relay that is to be switched.

Convert the circuit logic into blocks by working through the circuit, starting at the output and ending at the input:

Step 1: The make contact S3 is interconnected in series to output Q1 and to a further circuit element. A series connection corresponds with the AND block:

I3

&

Q1 x

Step 2: S1 and S2 are connected in parallel. A parallel circuit corresponds with the OR block:

I1

I2 x

1

I3 x

&

Q1

Unused inputs

The circuit program automatically assigns the unused connectors a status that ensures proper functioning of the relevant block. If you like, you can label unused connectors with an ’x’ identifier.

In our example we shall use only two inputs of the OR block and two inputs of the AND block; the relevant unused third and fourth inputs are identified at the connector with an ’x’.

Now connect the I/Os to the LOGO! .

64

LOGO! Manual

Wiring

Connect the switches S1 to S3 to the screw terminals of your LOGO! :

Programming LOGO!

3.5 The four golden rules for operating

LOGO!

Rule 1

Changing the operating mode

You create the circuit program in

programming mode

.

After power is on, and when the display shows “No Program / Press ESC”, press the

ESC

key to select programming mode.

Timer and parameter values of an existing circuit program can be edited both in

parameter assignment mode

and in

programming mode

. During

parameter assignment

the LOGO! is in

RUN mode

, i.e. it continues execution of the circuit program (see Chapter 5). To work in

programming mode,

you need to terminate the circuit program by calling the

“Stop”

command.

Select the ’Start’ command on the main menu to set

RUN mode

.

When the system is in

RUN

, you can return to

parameter assignment mode

by pressing the

ESC

key.

When

parameter assignment mode

is open and you want to return to

programming mode

, select the

“Stop”

command from the parameter assignment menu, and confirm

“Stop Prg”

prompt with

“Yes”

. To do so, move the cursor to “

Yes

” and confirm with OK.

For more details on operating modes, refer to Appendix D.

Note

The following applies to 0BA2 device versions and earlier:

You can open programming mode by pressing + +

OK

.

You set parameter assignment mode by pressing

ESC

+

OK

.

66

LOGO! Manual

A5E00380835-01

Programming LOGO!

Rule 2

Outputs and inputs

Always create your circuit program by working from the output to the input.

You can connect an output to several inputs, but not the same input to several outputs.

Within the same program path you may not connect an output to an upstream input. For such internal recursions you should interconnect flags or outputs.

Rule 3

Cursor and cursor movement

The following applies when you edit a circuit program:

You can

move the cursor

when it appears in the form of an underscore:

– Press , , or to move the cursor in the circuit program.

– Press

OK

to change to ”Select connector/block”

– Press

ESC

to exit programming mode.

You

select a connector/block

when the cursor appears as solid square

– Press or to select a connector or a block.

– Confirm with OK.

– Press

ESC

to return to the previous step.

Rule 4

Planning

Before you start to create a circuit program, you should either first create design on paper or program LOGO!

directly using LOGO!Soft Comfort.

LOGO! can only save complete and faultless circuit programs.

What is meant by: ”LOGO! is in RUN”?

In RUN mode, LOGO! executes the circuit program. To do so, LOGO! first reads the status at the inputs, determines the status of the outputs by means of the user program, and switches these on or off according to your settings.

This is how LOGO! indicates the I/O status:

I:

0.. 123456789

1..0123456789

2..01234

Input/output status is ’1’: inverted

Input/output status is ’0’: not inverted

Q:

0.. 123456789

1..0123456

In this example, only the inputs I1, I15, Q8 and Q12 are set

“high“.

When switch S1 is closed, the status at input I1 is hi.

LOGO! computes the output states by means of the circuit program.

Output Q1 = ’1’, in this case.

When Q1 = ’1’, LOGO! sets relay Q1, and the load connected to Q1 is supplied with voltage.

3.7.7 Second circuit program

Up to this point, you have successfully created your first circuit, and assigned it a name and, if desired, a password.

In this section we are going to show you how to modify existing circuit programs and how to use the special functions.

Using this second circuit program, we are going to show you how to:

Add a block to an existing circuit program.

Select a block for a special function.

Assign parameters.

Modifying circuits

We shall use the first circuit program as a basis for the second, with some slight modifications.

Let us take a first look at the circuit diagram for the second circuit program:

3.8 Memory space and circuit dimensions

The size of a circuit program in LOGO! is limited by the memory space (memory used by the blocks).

Memory areas

Program memory

:

LOGO! allows only a limited number of blocks in your circuit program.

The second limitation is based on the maximum number of bytes a circuit program may contain. The total number of bytes used can be determined by adding up the number of bytes used for the relevant function blocks.

Retentive memory (Rem)

:

In this area, LOGO! stores process variables which need to be retentive, e.g. the hours counter value.

Blocks with optional retentivity use this memory area only if this function is actually enabled.

Resources available in LOGO!

A circuit program in LOGO! can occupy the following maximum resources:

Bytes

2000

Blocks

130

LOGO! monitors memory utilization, and offers only those functions from the lists for which it can actually provide sufficient memory space.

Utilization of memory areas

The system indicates that there is insufficient memory space by not allowing you to add a further block to your circuit program. LOGO! offers you only the blocks for which it can provide sufficient memory space. If LOGO! memory space is insufficient to hold any further blocks you select from a block list, the system will deny access to this list.

If memory space is fully occupied, optimize your circuit program or install a second LOGO!

Organization

LOGO! provides you with various elements in programming mode. In order to maintain the overview, we have organized the elements in ’Lists’. These lists are:

Co

: Connector list (

Co

nnector)

(see Chapter 4.1)

GF

: List of the basic functions AND, OR, ...

(refer to Chapter 4.2)

SF

: List of the special functions

(refer to Chapter 4.4)

BN

: List of reusable blocks configured in the circuit program

List contents

All lists show the elements available in LOGO! Usually, this includes all connectors, basic functions and special functions the LOGO! knows. This includes all the blocks you have created in LOGO! by the time you call the

BN

list.

If not all is shown

LOGO! does not show all elements if:

No further blocks may be added.

This is either an indication of insufficient memory space or that the maximum number of blocks has been reached.

A specific block’s memory space requirement would exceed the space available in LOGO!

See Chapter 3.8.

LOGO! functions

4.1 Constants and connectors – Co

Constants and connectors (= Co) represent inputs, outputs, flags and constant voltage levels (constants).

Inputs:

1) Digital inputs

Digital inputs are identified with an

I.

The number of the digital inputs (I1, I2, ...) corresponds to the number of the input connectors of the LOGO! Basic and of the connected digital modules, in the order of their installation. See the figure below.

2) Analog inputs

The LOGO! versions LOGO! 24, LOGO! 24o,

LOGO! 12/24RC and LOGO! 12/24RCo are equipped with the inputs I7 and I8, which can also be programmed for use as

AI1

and

AI2

inputs. Signals at the I7 and I8 inputs are interpreted as digital values, and those at the AI1 and AI2 inputs are interpreted as analog values. The inputs of a connected analog module are numbered according to the already existing analog inputs. Special functions whose inputs should only be connected to analog inputs are offered in programming mode when you select the input signal, i.e. the analog inputs AI1...AI8, analog flags

AM1...AM6, the block numbers of a function with analog output or the analog outputs AQ1 and AQ2.

Outputs:

1) Digital outputs

Digital outputs are identified by the character

Q

. The output numbers (Q1, Q2, ... Q16) correspond with the numbers of the output connectors at the LOGO! Basic and with those of the expansion modules, in their order of installation. See the following figure.

112

LOGO! Manual

A5E00380835-01

LOGO! functions

There are also 16 blank outputs available. These are identified with an

x

and can not be reused in a circuit program (in contrast to flags, for example). The list shows all programmed blank outputs, and one blank output which is not yet configured. A blank output, for example, is useful for the special function “Message texts” (see Chapter 4.4.23), if only the message text is of significance to a circuit program.

2) Analog outputs

Analog outputs are identified by the letters

AQ

. Two analog outputs are available, namely AQ1 and AQ2. An analog output can only be connected with the analog input of a function, an analog flag AM or an analog output connector.

Flag blocks

Flag blocks are identified by the letters

. These are virtual outputs, which output the value of their inputs.

LOGO! provides 24 digital flags M1 ... M24 and 6 analog flags AM1 ... AM6.

LOGO! Manual

A5E00380835-01

113

LOGO! functions

Startup flag

Flag M8 is set in the first cycle of the user program and can thus be used in your circuit program as startup flag. This signal is automatically reset after the circuit program has completed its first cycle.

The M8 flag can be used in all further cycles for setting, deletion and evaluation procedures in the same way as other flags.

Note

The output of the flag always carries the signal of the previous program cycle. This value does not change within the same program cycle.

Shift register bits

LOGO! provides the shift register bits S1 to S8, which are assigned the read-only attribute in the circuit program. The content of shift register bits can only be modified by means of the “Shift register” special function (see Chapter 4.4.25).

Cursor keys

Up to four cursor keys are available to you, namely C ,

C , C and C (”C” = “Cursor”). Cursor keys are programmed for the circuit program in the same ways as other inputs. You can set the cursor keys in the corresponding display while the system is in RUN (see Chapter 3.7.6), and in an active message text (ESC + Key). Cursor keys can save switches and inputs, and allow operator control of the circuit program.

Levels

Voltage levels are designated

hi

and

lo

. A constant “1” = hi or “0” = lo status at the block can be set by means of a permanent voltage level or constant value hi or lo.

Open connectors

Unused block connectors can be identified with an

x

.

4.2 Basic functions list – GF

Basic functions represent simple logical elements of Boolean algebra.

You can invert the inputs of individual basic functions , i.e.

the circuit program inverts a logical “1” at a relevant input to a logical “0”; if “0” is set at the input, the program sets a logical “1”. A programming example is found in

Chapter 3.7.3.

The GF list contains the basic function blocks you can use for your circuit program. The following basic functions are available:

4.3 Basics on special functions

Because of their different input designation, you can see right away that there is a difference between the special functions and basic functions. SFs contain timer functions, retentive functions and various parameter assignment options, which allow you to adapt the circuit program to suit your own requirements.

This section provides you with a brief overview of input designations and with some particular background information on SFs. The SFs in particular are described in

Chapter 4.4.

124

LOGO! Manual

A5E00380835-01

LOGO! functions

4.3.1 Designation of the inputs

Logical inputs

Here, you will find the description of the connectors you can use to create a logical link to other blocks or to the inputs of the LOGO! unit.

S (Set):

A signal at input S sets the output to logical “1”.

R (Reset):

The reset input R takes priority over all other inputs and resets the outputs.

Trg (Trigger):

This input is used to trigger the start of a function.

Cnt (Count):

This input is used for counting pulses.

Fre (Frequency):

Frequency signals to be evaluated are applied to this input.

Dir (Direction):

This input determines the direction of count, for example.

En (Enable):

This input enables a block function. When this input is

“0”, other signal from the block will be ignored.

Inv (Invert):

A signal at this input inverts the output signal of the block.

Ral (Reset all):

All internal values are reset.

Connector X at SF inputs

SF inputs connected to connector x are set low. That is, the inputs carry a ’lo’ signal.

LOGO! Manual

A5E00380835-01

125

LOGO! functions

Parameter inputs

At some of the inputs you do not apply any signals. You configure the relevant block values instead. Examples:

Par (Parameter):

This input will not be connected. Here, you set the relevant block parameters (times, on/off thresholds etc.).

No (Cam):

This input will not be connected. Here, you configure the time patterns.

P (Priority):

This is an open input. Here, you define priorities and specify whether a message is to be acknowledged in

RUN.

4.3.2

Time response

Parameter T

At some of the SFs it is possible to configure a time value

T. When you preset this time, note that your input values are based on the timebase set:

Timebase

s (seconds) m (minutes) h (hours)

_ _ : _ _

seconds :

1

/

100

seconds minutes : seconds hours : minutes

126

B1 +

T =04:10h

Setting a time T of 250 minutes:

Unit in hours h:

04:00 hours

00:10 hours

=

240 minutes

+10 minutes

250 minutes

Note

Always specify a time T in 0.02 s. The time T is not defined for T 0.02 s.

LOGO! Manual

A5E00380835-01

LOGO! functions

Accuracy of T

Because of slight tolerances in the characteristics of electronic components, the set time T may deviate. The LOGO!

has a maximum tolerance of 0.02 %.

When 0.02 % of the time T is smaller than 0.02 seconds, the maximum deviation is 0.02 seconds.

Example:

The maximum tolerance per hour (3600 seconds) is

0.02 %, which is proportional to 0.72 seconds.

The maximum toloerance per minute (60 seconds) is

0.02 seconds.

Accuracy of the timer (weekly/yearly timer)

To prevent timing inaccuracy of the real-time clock in C versions caused by this deviation, the timer value is continuously compared with a high-precision timebase and corrected. The resultant maximum timing inaccuracy is 5 s/day.

4.3.3 Backup of the real-time clock

Because the internal real-time clock of a LOGO! is backed up, it continues operation after a power failure. The ambient temperature influences the backup time. At an ambient temperature of 25

°

C , the typical backup time is 80 hours.

If there is a power outage of a LOGO! for more than 80 hours, the internal clock responds, dependent on the equipment series, as shown below:

LOGO! Manual

A5E00380835-01

127

LOGO! functions

Equipment series 0BA0:

On restarting, the clock is set to “Sunday 00:00 1 January”. The time starts to run. Due to this, the system processes the time switches, which trigger actions, if necessary.

Equipment series 0BA1 and later:

On restarting, the clock is set to “Sunday 00:00 1 January”. The time is stopped and flashes. LOGO! is back in the status that it was in before the power outage.

In the RUN status, the system processes the counters that were parameterized with the time above. The clock is, however, still stopped.

4.3.4 Retentivity

The switching states and counter values of SFs can be set retentive. This means that current data are retained after a power failure, and that the block resumes operation at the break point. The timer is not reset, but resumes operation until the time-to-go has expired, for example.

To enable this response, however, the relevant functions must be set retentive. Two options are available:

R: The data is retained.

/

: Current data is not retained (default). See the example on

Page 91.

The hours counter is an exception because this function is always retentive.

4.3.5 Parameter protection

In the parameter protection settings, you can determine whether the parameters can be displayed and edited in

LOGO! parameter assignment mode or not. Two options are available:

+

: The parameter attribute permits read/write access in parameter assignment mode (default).

: The parameter settings are read-/write-protected in parameter assignment mode, and can be edited only in programming mode. See the example on Page 91.

4.3.6 Calculating the gain and offset of analog values

A sensor is connected to the analog input and converts a process variable into an electrical signal. This value of signal lies within the typical range of this sensor.

LOGO! always converts the electrical signals at the analog input into digital values from 0 to 1000.

A voltage of 0 to 10 V at input AI is transformed internally into range of values from 0 to 1000. An input voltage exceeding 10 V is shown as internal value 1000.

Because you can not always process the range of values from 0 to 1000 as predetermined by LOGO!, you can multiply the digital values by a gain factor and then shift the zero of the range of values (offset). This allows you to output an analog value to the LOGO! display, which is proportional to the actual process variable.

Mathematical rule

Actual value

Ax

=

(internal value at input Ax gain) + offset

Gain and offset calculation

The gain and offset is calculated based on the relevant high and low values of the function.

Example 1:

The available thermocouples have the following technical data: –30 to +70 C, 0 to 10 V DC (i.e. 0 to 1000 in LOGO!).

Actual value

= (internal value gain) + offset, thus

–30

+70

Example 2:

= (0 A) + B, i.e. offset B = –30

= (1000 A) –30, i.e. gain A = 0.1

A pressure sensor converts a pressure of 1000 mbar into a voltage of 0 V, and a pressure of 5000 mbar into a voltage of 10 V.

Actual value

= (internal value gain) + offset, thus

1000

5000

= (0 A) + B, i.e. offset B = 1000

= (1000 A) +1000, i.e. gain A = 4

4.4 Special functions list – SF

When you create your circuit program in LOGO!, you find the special function blocks in the SF list.

You can invert the inputs of SFs individually, i.e. the circuit program converts a logical “1” at the input into a logical “0”; a logical “0” it converts into a logical “1”. An example of the program code found in Chapter 3.7.3.

The table also specifies whether the relevant function can be set retentivity (Rem). The following SFs are available:

Symbol in

LOGO!

Wiring Description

Input Trg

Parameter

Output Q

You start the on-delay with a negative edge (1 to 0 transition) at input Trg (Trigger).

T represents the time after which the output is switched on (0 to 1 transition of the output signal).

Retentivity:

/ = no retentivity

R = the status is retentive.

Q is switched on when the set time T has expired, provided Trg is still set.

Parameter T

Please note the defaults for parameter T in Chapter 4.3.2.

The time for parameter T can also be preset based on the actual value of another, already configured function. You can use the actual values of the following functions:

Analog comparator (actual value Ax – Ay, see Chapter 4.4.18)

Analog threshold trigger (actual value Ax, see Chapter 4.4.16)

Analog amplifier (actual value Ax, see Chapter 4.4.20)

Each weekly timer has three cams you can use to configure a time hysteresis. You specify the on- and off-times at the Cam parameters. The weekly timer sets the output at a certain on-time, if this is not already set.

The weekly timer resets the output at a certain off-time, if it is not switched off already. You will cause a conflict if the on- and off-times you set for the weekly timer are identical, though set on different cams. In this case, cam3 takes priority over cam2, whereas cam2 takes priority over cam1.

The switching state of the weekly timer is determined by the status of all three cams.

Weekly timer: Example

The output of the weekly timer switch is to be set daily from

05:30 h to 07:40 h. The output should also be set every

Tuesday from 03:10 h to 04:15 h, and at the weekends from 16:30 h to 23:10 h.

This requires three cams.

Calculation rule

If the On threshold Off threshold, then:

Q = 1, if Cnt On

Q = 0, if Cnt < Off.

If the On threshold < Off threshold, then Q = 1, if On Cnt < Off.

Default on/off parameters

The default limits for the on and/or off parameters can be derived from another, already programmed function. You can use the actual values of the following functions:

Analog comparator (actual value Ax – Ay, see Chapter 4.4.18)

Analog threshold trigger (actual value Ax, see Chapter

4.4.16)

Analog amplifier (actual value Ax, see Chapter 4.4.20)

Analog multiplexer (actual value AQ, see Chapter

4.4.26)

Analog ramp (actual value AQ, see Chapter 4.4.27)

PI controller (actual value AQ, see Chapter 4.4.28) and

Up/down counter (actual value Cnt).

Select the required function by means of the block number.

For information on parameter defaults, refer to Chapter 4.4.1.

Note

The system scans the counter limit value cyclically.

Thus, if the pulse frequency at the fast inputs I5/I6 is faster than the cycle time, the special function might not switch until after the specified limit value is exceeded.

Example: Up to 100 pulses per cycle can be counted; 900 pulses have been counted so far. On = 950; Off = 10000.

The output is set in the next cycle, after the value has reached 1000. (The output would not be set at all if the value Off = 980.)

Limit value of OT

The value of the operating hours in OT are retained when you reset the hours counter with a signal at input R. The hours counter OT continues the count as long as En = 1, irrespective of the status at the reset input R.

The counter limit of OT is 99999 h.

The hours counter stops when it reaches this value.

In programming mode, you can set the initial value of OT.

The counter starts operation at any value other than zero.

MN is automatically calculated at the START, based on the

Reducing the input response of the analog comparator

You can selectively delay the output of an analog comparator by means of the “On-delay” and “Off-delay” special functions. With on-delay, output Q is only set if the pulse width of the triggering signal at input Trg ( =analog comparator output) is longer than the on-delay time.

Using this method, you will obtain a virtual hysteresis and reduce the input response to short signals.

The actual value Ax is output at AQ.

Using the analog input value of a potentiometer

You can acquire the analog input value of a potentiometer by interconnecting an analog input with an analog amplifier and an analog flag.

Scale the analog value at the analog amplifier for further use.

Connect, for example, the time base for parameter T of a time function (e.g. On-/Off-delay, Chapter 4.4.3) or the on and/or off limit specification of an up/down counter

(Chapter 4.4.13) to the scaled analog value.

The function reads the value at input In with a positive edge

(0 to 1 transition) at input Trg (Trigger).

This value is applied to shift register bit S1 or S8, depending on the shifting direction:

Shift up: The value at input In is set at S1; the previous value at S1 is shifted to S2; the previous value at S2 is shifted to S3 etc.

Shift down: The value at input In is set at S8; the previous value at S8 is shifted to S7; the previous value at

S7 is shifted to S6 etc.

Output Q returns the value of the configured shift register bit.

If retentivity is disabled, the shift function restarts at S1 or

S8 after a power failure. When enabled, retentivity always applies to all shift register bits.

Functional description

If the input En is set, then the function issues the analog value StSp at output AQ for the first 100 ms.

Then, depending on the connection of Sel, the function runs from value StSp to either level 1 or level 2 at the speed set in Rate.

If the input St is set, then the function runs to the value

StSp at the speed set in Rate. Then the function issues the value StSp at output AQ for 100 ms. Then the function issues 0 at the output AQ.

If the input St is set, the function can only be restarted once the inputs St and En have been reset.

If input Sel has been changed, depending on the connection of Sel, the function runs from Level 1 to Level 2 or the other way round.

If the input En is reset, the function immediately issues 0 at output AQ.

The analog value at the output is recalculated every 100 ms.

LOGO! functions

Parameter p (number of decimals)

Applies only to the AQ, PV, SP, Min and Max values displayed in a message text.

Timing diagram

The nature, manner and speed with which the AQ changes depend on the parameters KC and TI. Thus, the course of

AQ in the diagram is merely an example. A control action is continuous; therefore the diagram portrays just an extract.

228

1. A disturbance causes the PV to drop, as Dir is positioned upwards, AQ increases until PV corresponds again to SP.

2. A disturbance causes the PV to drop, as Dir is positioned upwards, AQ decreases until PV corresponds again to SP.

Dir is coordinated to the basic conduct of a control loop.

As the basic conduct of a control loop does not really alter, the change in Dir here is shown for the purposes of clarification.

LOGO! Manual

A5E00380835-01

LOGO! functions

3. As AQ is set to 0 by means of the input R, PV changes.

This is based on the fact that PV increases, which on account of Dir = upwards causes AQ to drop.

Functional description

If the input A/M is set to 0, then the special function issues output AQ with the value that you set with parameter Mq.

If the input A/M is set to 1, then automatic mode commences. As an integral sum the value Mq is adopted, the controller function begins the calculations.

Note

For further information on the controller basics please refer to the Online Help for LOGO!Soft Comfort.

The updated value PV is used to calculate in the formulas:

Updated value PV

= (PV gain) + offset

If the updated value PV = SP, then the special function does not change the value of AQ.

Dir = upwards (+) (timing diagram numbers 1. and 3.)

– If the updated value PV > SP, then the special function reduces the value of AQ.

– If the updated value PV < SP, then the special function increases the value of AQ.

Dir = downwards (–) (timing diagram number 2.)

– If the updated value PV > SP, then the special function increases the value of AQ.

– If the updated value PV < SP, then the special function reduces the value of AQ.

With a disturbance, AQ continues to increase / decrease until the updated value PV again corresponds to SP. The speed with which AQ changes depends on the parameters

KC and TI.

LOGO! Manual

A5E00380835-01

229

LOGO! functions

If the input PV exceeds the parameter Max, then the updated value PV is set to the value of Max. If the PV falls short of the parameter Min, then the updated value PV is set to the value of Min.

If the input R is set to 1, then the AQ output is reset. As long as R is set, the input A/M is disabled.

Sampling time

The sampling time is fixed at 500 ms.

5 Configuring LOGO!

When speaking of ’parameter assignment’, we refer to the configuration of the block parameters. You can set delay times for time functions, the switching times of the timers, the counter threshold value, the monitoring interval of an hours counter and the on and off thresholds of the trigger.

You can configure the parameters

In programming mode

In parameter assignment mode

In programming mode, the author of the circuit program also sets the parameters.

We have added the parameter assignment mode to allow the editing of parameters without having to modify the circuit program. This feature is available for the user to edit parameters, without having to change to programming mode, for example. The advantage: The circuit program remains protected, but can be adapted by the user to meet specific requirements.

Note

In parameter assignment mode, the LOGO! continues execution of the circuit program.

6 LOGO! program module (card)

LOGO! allows you to store only one circuit program in its memory. If you want to modify the circuit program or create a further one without deleting the first, you must archive it somewhere. One of the options is to use a program module/card.

The circuit program stored in LOGO! can be copied to a program module (card). You can then insert the program module/card in another LOGO! to copy the circuit program.

using the program module (card), you can:

Archiving circuit programs

Reproducing circuit programs

Send circuit programs by mail

Write and test your circuit program at the office, and then transfer it to a LOGO! in the switching cabinet.

LOGO! is supplied with a hood. The program module (card) is supplied separately.

Note

You do

not

need a module to backup the circuit program in your LOGO!.

The LOGO! circuit program is automatically stored in nonvolatile memory when you exit the programming mode.

We shall now introduce the program module (Card) you can order for LOGO! The card can backup all data in the

LOGO! circuit program memory.

The order number is found in the appendix.

Data written to the program module (card) in a 0BA5 version can be read in all 0BA5 versions.

... to earlier versions (0BA0 to 0BA3 devices):

A program module (card) that contains data written in earlier versions (0BA0...0BA3 devices) can not be used in

LOGO! devices of the 0BA4 or 0BA5 generation. When the

LOGO! system detects such an ’old’ program module

(card), the message “Unknown Card / Press ESC” is output to the display.

Vice versa, an 0BA4 or 0BA5 program module (card) can not be used in LOGO! devices of the 0BA0...0BA3 family.

6.1 Security function (CopyProtect)

We principally distinguish between program modules (card) with and without circuit program/copy protection.

Unprotected program module (card)

You can edit circuit programs without restrictions, and exchange data between the program module (Card) and the device.

Protected program module (card)

A circuit program is

protected

when it is transferred from a protected program module (card) to the LOGO!.

To execute this circuit program in LOGO!, the protected program module (card) must remain inserted during RUN, i.e. the circuit program stored on the program module

(card) can not be copied to other LOGO! devices.

Over and above that, a protected circuit program is write– protected.

A circuit program with

password

protection is no longer protected after the correct password has been entered, i.e.

you can then edit the program and remove the module.

Note

You need to assign a password when you create the circuit program for a protected module (card) to be able to edit it at a later time (see Chapter 3.7.5).

B Determining the cycle time

The program cycle is the complete execution of the circuit program, that is, primarily the reading in of the inputs, the processing of the circuit program and the subsequent reading out of the outputs. The cycle time is the time required to execute a circuit program once in full.

The time required for a program cycle can be determined using a short test program. This test program is created in

LOGO! and returns a value during its execution in parameter assignment mode from which the current cycle time is derived.

Test program

1. Create the test program by linking an output to a threshold trigger and connecting the trigger input with an inverted flag.

2. Configure the threshold trigger as shown below. A pulse is generated in each program cycle due to the inverted flag. The trigger interval is set to 2 seconds.

= cycle time in s

Explanation

The inverted flag block changes its output signal at each program execution. Thus, one logic level (high or low) width is exactly equivalent to the length of one cycle. Hence, a period lasts 2 cycles.

The threshold trigger indicates the ratio of periods per 2 seconds, which results in the ratio of cycles per second.

C LOGO! without display

Because some specific applications do not require operator control and monitoring units such as buttons or a display, we provide the LOGO! 12/24RCo, LOGO! 24o,

LOGO! 24RCo and LOGO! 230RCo versions without display.

Less is definitely more!

The versions without display offer you the following benefits:

Even more cost-effective without the operating element.

Requires less switch cabinet space than conventional hardware.

Substantial benefits with regard to flexibility and prime costs compared to stand-alone electronic switchgear.

Of advantage even for applications in which merely two or three conventional switching devices can be replaced.

Very easy to use.

Access protected.

Compatible to LOGO! versions with display.

Offers the option to read data by means of LOGO!Soft

Comfort.

LOGO! without display

Creating a circuit program without operator panel

There are two ways to create a circuit program for a LOGO!

without display:

You create the circuit program with LOGO!Soft Comfort on your PC and then download it to the LOGO!

(see Chapter 7).

You download the circuit program from a LOGO! program module (card) to your LOGO! without display

(see Chapter 6).

Operating characteristics

LOGO! is ready for operation when power is switched on.

Switching off a LOGO! without display is equivalent to disconnecting the power supply, e.g. as if you were removing the plug.

The circuit program of LOGO!...o versions can not be started or stopped by means of buttons. This is why the

LOGO!...o versions have other startup characteristics:

Startup characteristics

If there is no circuit program in the LOGO! or on the inserted program module (card), LOGO! remains in STOP.

If there is a valid circuit program in LOGO! memory, the

LOGO! automatically switches from STOP to RUN when power is switched on.

The circuit program on an inserted program module (card) is automatically copied to the LOGO!, immediately after power is switched on. The existing circuit program in

LOGO! memory is overwritten. The system automatically changes from STOP to RUN.

Provided the PC cable is connected to the LOGO!, you can download the circuit program to LOGO! and start it by means of the LOGO!Soft Comfort PC software

(see Chapter 7.1).

306

LOGO! Manual

Operating status indication

Operating states, e.g. Power On, RUN and STOP are indicated by an LED on the front hood.

Red LED:

Green LED:

Power On/STOP

Power On/RUN

The red LED is lit after Power On and in all LOGO! states other than RUN. The green LED is lit when LOGO! is in

RUN mode.

Reading current data

LOGO!Soft Comfort (see Chapter 7) provides an online test for reading the current data of all functions while the system is in RUN.

If your LOGO! without display holds a protected program module (card), you can not read the current data unless you enter the correct password for your the circuit program.

The circuit program is otherwise deleted from LOGO! memory when you remove the program module (card) to connect the PC cable, for example (see Chapter 6.1).
