I have a problem with the PLC SIM monitor, sometimes it show me some errors about nonexistent address, as is shown in the attachment....

We are using the FC105 from "S5-S7 Converting" from Standard Library, and we renamed it as FC305.

This is the second simulation with a S5-S7 Migration, and is the first time that we are addressing drives with the PLC SIM (Simoreg and Masterdrives).

As we are doing an actualization from a S5 system to S7, we need to correct the errors in order to look for more....

The question is: how could we eliminate periphery errors like those, in the PLCSIM? Without using the OB121 and 122.
