12.9 Removal of components
The modules to be removed and their connected sensors and actuators are no longer of any
significance to the process being controlled. The fault-tolerant system is operating in the
redundant system state.
Procedure
Follow the steps below to remove hardware components from a fault-tolerant system in
SIMATIC PCS 7. Details of each step are described in a subsection.
Step What to do?
1

Change hardware configuration offline

2 Editing and downloading the user program
3 Access H-CiR wizard
4 Modification of hardware

(see Removal of interface modules (Page 216)).
12.9.1 Change hardware configuration offline
Starting situation
The fault-tolerant system is operating in the redundant system state.
Procedure
1. Perform offline only the configuration modifications relating to the hardware being
removed. As you do, delete the icons to the channels that are no longer used.
2. Compile the new hardware configuration but do not yet download it to the PLC.
