Instructions:
In this example, a CP1613 is used for the S7 communication for a user application to an S7-400H system on the Ethernet. The requirement for the procedure described is an existing configuration of the S7400-H system with network connection.

Warning:
Fault-tolerant S7 connections are available only for CP1613 and CP1623. It is not possible to use standard network cards in this case.

General information:
The requirement is that one of the two following configuration tools is installed on the Engineering Station.

• NCM PC:
  NCM PC is supplied with the SIMATIC NET CD and permits you to create PC projects and open STEP 7 projects. However, it is not possible to use this software to edit the S7 blocks in the STEP 7 project.
   
• STEP 7:
  STEP 7 is a separate software package and permits you to create S7-400, S7-300 and PC projects. It is possible to use this software to edit the S7 blocks.

Note:
You need an Engineering Station with STEP 7 for commissioning the PC station. STEP 7 is mandatory for configuring a fault-tolerant S7 connection between PC station and S7400-H system.
You need the license for the SIMATIC NET PC software S7-REDCONNECT on the PC station that communicates with the S7400-H system via fault-tolerant S7 connections.

Please follow the instructions below for configuring the PC station.
