Hello every one
I have a serious problem here with two PLCs , S7-400 and S7-200. The problem is, I have a single sensor which I need to connect to both 400 and 200 CPUs. Unfortunately I have no possibility to make a network because 400 DP and MPI ports are already reserved for communicating with other PLCs and the port on the 200 is reserved for a HMI. in other hand, I have no access to any hardware module in the jobsite. I thought I can import the analog signal to s200 and send it to the s400 using the analog output card (232-0Hd22). But I don’t know if it’s possible to use an output module on the s200 as an input for an input module on a s400. Please help…
By the way, the connection on the S200 output includes 3 terminals (M0 V0 I0) but the analog input card on the s400 includes only 2 wires (A+ A-)
