Siemens SIMATIC S7-400H - Removing Components in STEP 7

Communication
14.6 Communication via fault-tolerant S7 connections
S7-400H
252 System Manual, 03/2012, A5E00267695-11
Configuring connections
The PC must be engineered and configured as a SIMATIC PC station. Additional
configuration of fault-tolerant communication is not necessary at the PC end. The connection
configuration is uploaded from the STEP 7 project to the PC station.
You can find out how to use STEP 7 to integrate fault-tolerant S7 communication for a PC
into your OS system in the WinCC documentation.
