Product Information

Introduction

This product information describes supplements and corrections to the ET 200iSP Distributed I/O System Operating

Instructions, (A5E00247483-03), release 03/2008.

Section 3.12: System modification in a redundant system

There are plants that must not be closed down while they are running. This may be due to the complexity of the automated

process or because of the costs involved in restarting. A modification or removal of system components may nonetheless be

necessary.

Certain system configurations and parameters can be modified in RUN by means of a system modification while it is in use.

Processing of the process is held for a short period of time. The process inputs retain their last value during this time period.

Information on using this function in the redundant structure can be found in the S7-400H automation system, fault-tolerance

systems (http://support.automation.siemens.com/WW/view/en/1186523) manual and in the online help for the H option

Requirements

● as of STEP 7 V5.3 SP2 with HW update 0042 (version V3.0)

● PCS7 will be released with the next service packs for PCS7 V6.1, V7.0 and V7.1.

What points should you note when planning the ET 200iSP stations?

● Construct the ET 200iSP station entirely using terminal modules and a terminating module.

● Add components to the ET 200iSP with the necessary electronic modules. Fill the remaining slots with the reserve

modules. All the reserve modules must be inserted and there must be no gaps.

● You do not have to configure reserve modules.

Rules for making changes to the system while it is in use

● If you are modifying the real hardware configuration, there may be only one gap each. When removing the electronic

modules, replace the electronics modules by reserve modules; when adding electronic modules, replace the installed

reserve modules with electronic modules.

● If you have fitted a slot cover on the last free slot, it is not expandable.

● Note that terminal modules TM-RM/RM are required for electronic modules 2DO Relay UC60V/2A.

Example: Replacement of configured electronic modules

1. Replace the electronic modules or reserve modules with gaps in the configuration (HW config).

2. Execute the Save and Compile menu command.

3. Download the station configuration to the H station in RUN mode.

4. Change the real hardware configuration: Remove and install one module at a time (for example, remove slot 5 --> install

slot 5). Note: two empty slots are not permitted.

5. Replace the gaps in the configuration (HW config) with the new electronic modules.

6. Execute the Save and Compile menu command.

7. Download the station configuration to the H station in RUN mode.

Result

The system modification was successfully completed.
