8.4 Redundancy with IM 153-2
Use
You can operate the interface module IM 153-2 redundantly
• on the SIMATIC S7-400H (e.g. CPU 417-4H)
• with GSD file on any DP master (e.g. S5-115H)
When configuring with a GSD file, the redundant operation of the IM 153-2 interface
module can take place only in DPV0 mode. This operating mode is set differently
dependent on the configuration tool.
• with software redundancy
For the basic package STEP 7, the optional software SIMATIC S7 Software Redundancy is
required. The optional software includes an online help in which the use and function of
the software redundancy is described.
• to standard
Specification slave redundancy V1.2, Nov. 2004 of the PROFIBUS user organization; order
no: 2.212
– System Redundancy (SR)
– Flying Redundancy (FR)
Conditions for the ET 200M
• Configuration with active bus modules
The configuration with active bus modules 6ES7195-7HD10-0XA0 or
6ES7195-7HD80-0XA0 ensures a greater availability of the ET 200M.
• 2 x IM 153-2 on bus module BM IM/IM
The arrangement specifications named in the chapter "Installation (Page 58)" apply to the
active bus modules and interface modules used.
• Software redundancy and system redundancy (SR) are possible with the IM 153-2 / -2 FO
as of 6ES7153-2AA02-0XB0 / -2AB01-0XB0
• Flying redundancy (FR) is possible with IM 153-2 / -2 FO as of 6ES7153-2Bxx1-0XB0
– The redundant master system must be configured in accordance with the demands on
H systems.
– The GSD file of the IM 153-2 (GSD rev. 5) must be imported to the configuration tool.
Note
STEP 7 offers no support for configuring an H system with flying redundancy.
