Prefereably it should remain as is, therefore telegram 1 and in case of an fault, the PLC should poll the error code with acyclic read. Any simple soultution?

The old project already used 352 telegram, but it had also OFF2/OFF3 input and sollereicht and n_null oututs. I guess I will add those extra signals to match the old FB.

For the addition outluts you have to modyfy the FB or readout the ZSW yourself.
