Product Overview 1Introduction

Signal modules for process automation are part of the S7-300 I/O module range,which offers functions in addition to those of “standard“ I/O modules:

• Process-related functions

– Pulse lengthening

– Flutter monitoring

• Enhanced diagnostics

• Provision of identification data

You can make full use of these additional functions in an ET 200M, which is usedin the PCS 7 process control system.

It is not possible to use the modules described in this manual in an S7-300(centralized configuration).

Declaration

The “signal modules for process automation“ are referred to below as “processcontrol modules“.

Hardware Requirements

You will require the IM 153-2 as of the following version as a DP slave interface:

• IM 153-2 as of 6ES7 153-2AA02-0XB0, Version 07

• IM 153-2 FO as of 6ES7 153-2AB01-0XB0, Version 06

Product Overview

Signal Modules for Process Automation1-2 A5E00085262-03

Software Requirements

You will require the following to configure and parameterize the process controlmodules:

• STEP 7 as of V 5.1 (SP1 or SP2) and SIMATIC PDM as of V 5.1

• STEP 7 as of V 5.1 SP3 (without SIMATIC PDM)

• PCS 7 as of V 5.1 or V5.2/V 5.2 SP1 and SIMATIC PDM as of V 5.1

• PCS 7 V 5.2 SP2 (without SIMATIC PDM)

• COM PROFIBUS as of V 3.0 and SIMATIC PDM as of V 5.1

• For use in non-SIEMENS systems: configuration software for the DP masterand SIMATIC PDM as of V 5.1

Note

When using STEP 7 as of V5.1 SP3 and PCS 7 V 5.2 SP2, you mustparameterize the modules of the process control system with STEP in HW-Config.

When using later versions of STEP 7, configuration is done with SIMATIC PDMas of V5.1. The subsequent chapter, in which the parameterization with SIMATICPDM is described, refers only to the STEP 7 Versions of V5.1 SP1 and 2 as wellas PCS 7 V5.1, V5.2, V5.2 SP1.

After upgrading to STEP 7 V5.1 SP3 or PCS 7 SP2, you must reparameterize themodule parameters of the already process control modules installed with STEP 7(HW-Config). You will the no longer be able to use the identification and messagefunctions of the process control modules.

Changing from STEP 7 V 5.1 later SP 3 to STEP 7 V 5.1 SP 3

Configuration is done only with HW-Config of STEP 7 V 5.1 SP3 will.

The use of PDM is not allowed as soon as STEP 7 V 5.1 SP3 is installed on yourengineering system.

You have configured your modules with PDM until now, proceed as follows:

1. The modules should not be deleted in the configuration so that the I/Oaddresses and symbols are retained.

If you deleted and reconfigure the modules, the I/O addresses may bereassigned and the symbols are to be remodified.

2. Reconfigure all the channels of the modules in the HW-Config.

3. Download the configuration to PLC.

Product Overview


Integration in Process Control System

The following section is valid for STEP 7 V 5.1 SP 1 and SP2 as well as for PCS 7V 5.1, V 5.2, V5.2 SP 1

PCS 7 is a powerful process control system. With PCS 7 and the process controlmodules, the ET 200M has a direction connection to the process control system.This is also evident from the following:

• Parameterization of the process control modules with SIMATIC PDM (add-onpackage for STEP 7)

• The evaluation and continued processing of the input/output signals is executedusing PCS 7 driver blocks in the DP master CPU.

Commissioning and Diagnostics


Configuration

This step involves configuring and parameterizing the ET 200M using theprogramming device.

Configuration

You configure the ET 200M with STEP 7 / COM PROFIBUS or with appropriateconfiguration software. At configuration, you only set the basic features of the DPslave (the network parameters, for example).

Parameter Assignment

At parameterization, you set the parameters of the ET 200M and the insertedmodules:

• You parameterize the ET 200M and “standard“ I/O modules with STEP 7.

• You parameterize the process control modules with SIMATIC PDM.

Cyclic Data Transfer Via PROFIBUS DP

Cyclic data transfer takes place between the CPU (S7-400, for example) and theET 200M. The following data is transferred:

• The cyclic user data of the inputs and outputs, including the input value status

• The diagnostic interrupts

This data is prepared in the CPU by the PCS 7 driver and the CFC (ContinuousFunction Chart) for system visualization. This data is then presented on the OS bymeans of WINCC.

The parameters (for network configuration, for example) are also transferredcyclically.

Acyclic Data Transfer Via PROFIBUS DP

Acyclic data transfer takes place between the process control modules of the ET200M and the programming device/PC (SIMATIC PDM). The process controlmodules of the ET 200M are parameterized by means of this acyclic data transfer.Information data is also transferred and displayed in SIMATIC PDM .

• Diagnoses and interrupts

• Data sets (only with S7)

2.5 Diagnostics by Means of the Process Input Image

Introduction

In addition to the diagnostic messages by means of LED and module/DPdiagnostics, the module 6ES7 321-7TH00-0AB0 also provides additionalinformation on the validity of each input signal – the value status. The value statusis stored in the process image like the input signal.

Value status

The value status is additional binary information on a digital input signal. The valuestatus is entered at the same time as the process signal in the process input imageand provides information on the validity of the input signal. The value status isinfluenced by

• Sensor or power failure

• Wire break check, short circuit in sensor line

• Flutter monitoring

• Diagnostics for the changeover contact type of sensor

Meaning of the value status:

• “1“: Signal is valid

• “0“: Signal is invalid



Digital Input and Value Status Assignment

In the process image, each input in the input word IW x of the module is assigned avalue status in the subsequent IW x+2.

Channel 1 input signal

Meaning of value status: 1: signal valid0: signal invalid


EW x

15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0

EW x+215 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0

Value status for channel 1




Figure 2-2 Digital Input and Value Status Assignment

Evaluation of the Value Status in PCS 7

The value status is evaluated in your CFC program with block FC 277 “CH_DI:Digital Input“. This module undertakes the processing of the digital input value ofS7-300-Digital input modules.

How the value status gets into the block:

1. Link the symbol created with STEP 7 in the symbol table for the digital inputchannel with the VALUE input parameter.

2. Link the status symbol of the value of the digital input channel with theVALUE_QC input parameter

3. Set the PQC = TRUE input parameter

4.3 Parameter Descriptions

4.3.1 Flutter monitoring

Introduction

Flutter monitoring is a process control function for digital input signals. It detectsand reports any unusual signal patterns such as, for example, when an input signalfluctuates too often between “0“ and “1“. The occurrence of such signal patternsindicates that the sensor is faulty or unstable.

Enabling Flutter Monitoring

You enable flutter monitoring by means of the “Diagnosis: Flutter error“ .

Tip: Also enable the group diagnosis at parameter assignment so that, if there is aflutter error, a diagnostic interrupt is also reported in addition to the diagnosticentry.

Detecting Unusual Signal Patterns

A parameterizable monitoring window is available for each input channel. Themonitoring window is started with the first change of the input signal. If the inputsignal changes more within the monitoring window than the parameterized numberof signal changes, this is recognized as a flutter error. If a flutter error is notdetected within the monitoring window, the monitoring window is started again atthe next signal change.

Reporting a Flutter Error

If a flutter error occurs, the current signal state is entered in the process image andthe value status of the signal is set to “invalid“. In addition, the “flutter error“ isentered as diagnostic information, and an incoming diagnostic interrupt is triggered.

You must evaluate and process the value status and the diagnostic information inthe user program.

Resetting a Flutter Error

If no further fluttering of the input signal is detected during the triple monitoringwindow, the diagnostic entry is removed and an outgoing diagnostic interrupt istriggered. The value status of the current signal in the process image is set to“valid“.

Principle

The following figure illustrates the principle behind flutter monitoring.

4.3.2 Pulse lengthening

Introduction

Pulse lengthening is a function for changing a digital input signal. A pulse at adigital input is extended to at least the parameterized length. The input signal willnot be changed if it is longer than the parameterized length.

Principle Behind Pulse Lengthening

The following figure illustrates with examples if and how input pulses are changed.

Pulse is longer than T1and is not changed

The second pulse, which occursduring pulse lengthening, isdelayed until completion of pulselengthening.

Figure 4-3 Principle Behind Pulse Lengthening



Note

If you parameterize pulse lengthening for an input channel, this also affects theflutter monitoring enabled for this channel. The “pulse-lengthened “ signal is theinput signal for flutter monitoring. Make sure therefore that the parameters for pulselengthening and flutter monitoring correspond to each other. By selecting theappropriate values for the parameters, you can customize the functions to suit yourprocess as well as possible.

4.4 Sensor

4.4.1 Connection Rules for Sensors

Introduction

Because of the large number of sensors that can be connected to the digital inputmodule, you must take the sensor load into account at configuration. You will findin this chapter ...

• recommendations on how to connect sensors

• An overview of the sensor-specific load

• A rule for the evaluation of the sensor-specific load

• An example

Sensors Can Be "Combined "

You can connect a wide variety of sensors to the SM 321; DI 16xNAMUR , andthese can also be “combined“.

At parameter assignment, you can specify which sensors are to be connected towhich channel group. The same sensor type is assigned to the channels of achannel group.

Changeover contact

Changeover contacts always occupy two adjacent inputs (for example, 0 and 1 or 2and 3, etc.). Make sure you adhere to the following rule:

• Always connect the normally open contact to the “even“ channel,

• Normally closed contact is always connected to “odd“ channel.

2 Sensor Supplies: 18 V and 8,2 V

The SM 321; DI 16xNAMUR has two different sensor supply voltages. Thefollowing table shows you which sensor to attach to which sensor supply:

18 V 8.2 V

Selection criteria:

• Operating voltage range (BERO terminal (+) and terminal (-)): 15 V to min. 20 V

• Transistor T1 functions as a switch (on/off)

• Protective measures:

– Spurious switch-on pulse suppressed

– Output A short circuit-proof

– Reverse polarity protection

– Wire break protection

– Anti-inductive protection

– Radio telephony protection

• Load capacity (T1) = 150 mA (at TA≤ 85 °C)



Performance Factors for BEROs from the "Low-Voltage Controlgear, Switchgearand Systems" Catalog

You will find a value in the table below that you can use to calculate the sensorload easily if:

• You use sensors from the “Low-Voltage Controlgear, Switchgear and Systems“NSK catalog from SIEMENS

• IC = 17 mA

You calculate the performance factor as follows: LF = 0.281 + IC x 9.5 = 0.442

You should not use the planned sensor connection above as follows:

• Can be used up to a maximum of 40 °C, but

• The sensor load is asymmetrical.

What to do:

• When you use the module up to a maximum of 40°C: Reassign the sensors tothe channels so that the sensor load is as symmetrical as possible.

• When you use the module up to a maximum of 60°C, use an additional moduleto reduce the sensor load below the specified factor of 3.7.

4.5.2 Diagnosis with a Sensor of the Changeover Contact Type

Brief Description

In the case of diagnosis with a sensor of the changeover contact type, the modulemonitors switching between 2 input channels. If after the specified switchover time(see the technical specifications) there is no change in signal on the partnerchannel, the module issues a diagnosis.

Purpose

You can use the diagnosis as follows:

• For a diagnosis of the sensor

• To check that there was definitely a switchover between the normally opencontact and the normally closed contact



Principle

If the digital inputs of a channel group are parameterized as “changeover contacts“,the module for this channel group carries out a diagnosis for the changeovercontact type of sensor. The tolerated switchover time between the two channels isfixed at 300 ms and cannot be changed.

If the check is negative, then:

• The module identifies the value status of the normally open contact channel as “invalid “.

• The module creates a diagnostic entry for the normally open contact channel.

• The module triggers a diagnostic interrupt.

The digital input signal and the value status are only updated for the normally opencontact channel. The digital input signal for the normally closed contact channel isfixed at “zero“, and the value status is set as “invalid“ because this channel is onlysupposed to check the sensor.

5.3 Diagnostics of the Digital Output Module

Diagnoses

In this table, you will find all the diagnostic messages of the digital output modulethat can occur in DP–Diagnosis and module diagnoses STEP 7.

The module reports the diagnoses for each channel. A visual indication is given bythe SF– LED.

You can activate/deactivate and parameterize the diagnosis by means of the“Group Diagnosis““ parameter.

Behavior at M-Short circuit

If output signal = “1“ the digital output module reports “M-Short circuit“.

If output signal = “0“ the digital output module switches to the safer status and theStatus-LED turns off.

Note: The digital output module reports a P-Short circuit regardless of the signalstatus.

Reference

You can find a detailed description of how to evaluate diagnostic information inSTEP 7 in the STEP 7 online help system.


Diagnostic Data 6In This Chapter

This chapter describes the structure of the diagnostic data in the system data. Youmust be familiar with this structure if you want to evaluate the diagnostic data of thesignal modules in the STEP 7 user program.

In PCS 7 , the CFC diagnostic block carries out the evaluation of the diagnosticdata automatically.

Further Sources

You can find a detailed description of the principle behind the evaluation of thediagnostic data of the signal modules in the user program and a description of theSFCs you can use to do this in the System and Standard Functions referencemanual.

Data Records 0 and 1 of the System Data

The diagnostic data of a module is contained in data records 0 and 1 of the systemdata area.

• Data record 0 contains 4 bytes of diagnostic data, which are the same for allmodules and describe the current status of an S7-300/ET 200M.

• Data record 1 contains:

– 4 bytes of diagnostic data of data record 0 and

– The remaining bytes containing the module-specific diagnostic data

Structure and Contents of the Diagnostic Data

Below you can find descriptions of the structure and contents of the individual bytesof the diagnostic data.

Generally speaking, if an error occurs, the corresponding bit is set to “1“.

Glossary 8BERO

A position switch that works without any touch or contact being involved. Adistinction is drawn between inductive and capacitive BEROs.

Flutter monitoring

Flutter monitoring is a process control function for digital input signals. It detectsand reports unusual process control signal patterns such as a fluctuation in theinput signal between“0“ and “1“that occurs too often.

Sensor

Sensors are used for the precise detection of digital signals and paths, positions,speeds, revolutions, weights, etc.

Identification Data

Identification data is information stored in a module that supports the user with thefollowing:

• Checking the configuration of a system

• Locating changes to the hardware of a system.

Pulse lengthening

Pulse lengthening is a function for changing a digital input signal. A pulse at adigital input is extended to at least the parameterized length. If the input pulse isalready longer than the parameterized length, it is not changed.

NAMUR

Normenausschuss für Mess- und Regelungstechnik (German standardizationcommittee for measurement and control engineering)

Changeover Contact

Auxiliary switch with only one contact piece that has a closed position for when theswitching device is closed and another closed position for when it is open.

Glossary


Value status

The value status is additional binary information on a digital input signal andprovides information on the validity of the input signal.
