Add Io Devices Or I/O Modules - Siemens SIMATIC CPU 410 System Manual

Note
IO devices that are to be added or removed do not have to be CiR-capable.
Note that the neighborhood relation on the ports may not be change in RUN for non-CiR-
capable devices. In the properties of the device ports, a partner port may only be entered for
"Topology" if it is ensured that nothing will change from this relationship. Otherwise, you
should select the "Any partner" setting. Only then can you remove the neighbor in a CiR
operation and add a new neighbor in another CiR operation.
All other plant changes mentioned below require a CiR-capable IO device connected to the
PROFINET IO system.
Back up your current configuration after each download of the station configuration from HW
Config (regardless of the operating state of the CPU). This is the only way for you to ensure
that you can continue working with the backed up project in case of an error (loss of data)
without loss of the CiR capability.
Note
SFB 52; 53 and 81
If SFB 52, SFB 53 or SFB 81 is called during a CiR operation on the line, the call is
acknowledged with error code 0x80C3.
Different update times
Please note the following if you have set "automatic" for the update time for an IO device
without CiR capability:
If you have set "automatic" for the update time and the CPU outputs a consistency error
during the CiR consistency check because the update time has changed for a non-CiR-
capable IO device, you can check the original project to see update time was achieved and
configure that time as the fixed update time for that IO device.
On a CiR-capable IO device on which CiR is run, the update time after that CiR operation
must be at least 1 ms. This is checked by the CPU.

Add IO devices or I/O modules

Procedure
Adding IO devices or I/O modules in RUN mode includes the following operating steps:
1. Expand and download the configuration with HW Config.
2. Rebuild the hardware.
3. Expand, test and download the user program.
You must adhere to this order of steps.
