Plant changes in RUN - CiR
11.1 Motivation for CiR via PROFINET IO
Configuration requirements for PROFINET IO
You need to select saving the data on the CPU for all components within the station for
which you can choose whether the configuration data is saved on the module itself or on the
CPU.
Software requirements
To make a configuration change in RUN, the user program must meet the following
requirement: It must be written so that station failures or module faults, for example, do not
result in a CPU STOP.
The following OBs must be available in your CPU:
● Hardware interrupt OBs (OB 40 to OB 47)
● Cycle time error OB (OB 80)
● Diagnostic interrupt OB (OB 82)
● Pull/plug module interrupt OB (OB 83)
● Priority class error OB (OB 85)
● Rack failure OB (OB 86)
● I/O access error OB (OB 122)
Note
These requirements are always met with SIMATIC PCS 7.
