Siemens SIMATIC ET 200iSP

Example con󹪝guration of a redundant bus system and the interface modules
The following 󹪝gure shows a con󹪝guration using an S7-400H as an example. You can 󹪝nd a
detailed description of H systems in the manual S7-400H Automation system, Introduction to
the system.

Figure 4-6 Redundancy with 2 x IM 152-1DP in one H system
S7-400H as DP master
You require STEP 7 V5.0 and higher and the SIMATIC S7 H systems software package to
con󹪝gure the S7-400H system.
DP master 1 and DP master 2:
• Run the same user program.
• Have the same parameter assignments and con󹪝guration for the IM 152-1DP.
4.12 Redundancy of the Power Supply
Properties
With the ET 200iSP you can set up a redundant power supply PS. When one power supply PS fails,
the system fails over to the second power supply PS without interruption.
Requirements
• Terminal module TM-PS-A
• Terminal module TM-PS-B
