Hello to all,

We have an S7-1200 that is accessed as an i-device slave from a master Fanuc PLC (which it accesses via a GSD generated from the TIAPortal). 

The idea is for this S7-1200 to be accessible by a second Siemens S7 master, also as an i-device slave. It will be accessed by both masters Fanuc PLC and the another S7 PLCs. 

Could this be possible? Thank you.

Hi Noxim

yes, the S7-1200 can be used as a so called shared I-Device by 2 I/O Controllers. See THIS link from the S7-1200 manual for an example configuration
