I need to communicate a PLC Siemens S7-1200 with Quattro, could someone help me, please?
Hi, this is bordering on impossible, both companies have proprietary protocols and interfaces, i don’t see a single common ground.
I’m almost submersed in the siemens plc world, but the 1200 series is only used for low cost applications, i have only commisioned one since they exist, but ~50 s7-15××.
These are much more open and there are things like can interfaces etc, but that would at best connect you to a gx-device.
You should be able to use Modbus TCP/IP to read and Write the Cerbo’s modbus map.

Thx, learned something, good instructions on youtube.
Have to see if it will also work for logo8 
It seems it is only possible with a gx-device as interface, which makes this expensive and not really transparent.
Depending on what you want to achieve it might be simpler using digital and analog io.
Try using a beagle bone or Rpi as a Venus interface, these are really flexible.
