6.1 Compatibility of modules
Station configuration with more than 32 I/O modules
Certain I/O modules with functional status 001 and 002 do not support a station
configuration with more than 32 I/O modules.
The following table shows all modules that do not support a station configuration with more
than 32 I/O modules.

Bumpless changeover of modules
You can find additional information on the bumpless changeover of modules in the Product
Information on the Internet
(https://support.industry.siemens.com/cs/ww/en/view/73021864).
Operation of modules in isochronous mode
Since the ET 200SP R1 system does not support isochronous mode, there is a corresponding
functional limitation with modules (e.g. TM Timer DIDQ 10x24) that require isochronous
mode for full functionality.
Data record repetition on redundancy switchovers
During a redundancy switchover, it may happen that a data record addressed to the module
does not reach the recipient or the data record response cannot be delivered. In these cases,
there is an automatic repetition of data records.
