Halo! The project that i am dealing with is to replace an old plc with S7400 with ET200M and S7300 modules.I will use PCS7 for SCADA. What module can i use? I found that in siemens sourcing module digital inputs are: 63S7321-1BH50-0AA0 (24vdc source input) the SM 321 64DI,DC24V Sinking/Sourcing module i have read that is not working with PCS7. Is it possible to use 63S7321-1BH50-0AA0 and to make a bridge between the common (0VDC) of the two power supplys (attachment)?
