Hii!
Now i use HSC1, mode 9 (A/B phase)in s7-200 224, with Encorcoder is Omron NPN (E6B2 CWZ6C).
But when i read HC1 value. It is always "0'.. so i think, the encorder didn't connect with PLC.
Is the problem OPEN COLLECTOR?
i connected : 1M<--> M, Clock A <--> i0.6, Clock B <--> i 0.7.
please help me!
Thansk so much!
