Permitted changes over PROFINET IO

Permitted configuration changes for PROFINET IO
The process introduced here supports the following changes to your AS:
● Adding and removing an IO device.
The IO device does not need CiR capability for this step.
The station address in the PROFINET IO subsystem of an IO device that is removed in a
CiR operation must not be added back again in the same CiR operation.
Station addresses that are removed in a CiR operation may not be added again in the
same CiR operation.
● Adding and removing I/O modules in the IO device.
The respective IO device does not need CiR capability for this step.
An I/O module that is removed with CiR must not be replaced with a different I/O module
in the same CiR step.
However, it is possible to remove I/O modules in a CiR operation and to add I/O modules
at a different location.
Addresses must not be changed in a CiR operation.
Addresses that are removed in a CiR operation may not be added again in the same CiR
operation.
● Changing parameters of the I/O modules.
The respective device does not need CiR capability for this step.
● Changing properties of the ports (PEDV), e.g. topology, monitoring, etc.
You cannot reconfigure the local PDEV submodules of the IO controller.
● Changing the update time
The IO device must have CiR capability.
● Changing process image partition assignment
Configuration changes in RUN are permitted for the interface module added in HW Config (in
HW Config: Properties of the interface module > "General" tab > "Short description" area >
"Configuration changes in RUN" entry
Rules for configuration changes
● You need at least two downloads to the CPU to replace an I/O module with an I/O module
of a different type for a configuration that already exists in the CPU:
– 1st CiR operation: The CPU receives the configuration that no longer contains the I/O
– 2nd CiR operation: The CPU receives the configuration with the newly added I/O
