Connection Of The Io Device Via System Redundancy - Siemens SIMATIC ET 200SP HA System Manual

Plant planning
4.8 Redundancy and changes during operation
Allow changes to the plant in runtime (CiR and H-CiR)
You can use the ET 200SP HA to create hardware configurations that allow certain changes to
be made during ongoing operation under defined conditions.
The following procedures should be followed to perform the changes.
● Use of CiR (Configuration in RUN) in a system with a single CPU - 1oo1
You can perform certain configuration changes during operation.
● Use of H-CiR (Configuration in RUN in a system with a redundant CPU - 1oo2)
You can perform configuration changes in subsystems with redundant CPU system
changes during operation.
You can find information on the configuration guidelines, requirements and procedures in the
system manual SIMATIC; Fault-tolerant systems; S7-400H

Connection of the IO device via system redundancy

Connection of the IO device with system redundancy
IO devices are connected to a redundant IO controller.
With system redundancy, all redundantly used components are in continuous operation. When
a redundancy partner fails, the function is maintained when the master role is assumed or a
different communication path is selected.
