Required software and configuration
You select and configure the redundant modules in HW Config.
● In order for both subsystems of the H system to be able to address redundant input/output
modules, S7 driver blocks from the "Redundant I/O" library and PCS 7 driver blocks from
the

You interconnect the signals in the CFC chart. You can find information on this in the section
"Configuration of redundant signals (Page 151)".
When the user program is compiled, the required driver blocks are placed, interconnected and
configured automatically.
