Hi Everybody

I have the following CP341 (RS422/485, MLFB: 6ES7-341-1CH01-OAE0) And CPU 315-2DP.

I want to send the following data from CP341 to DCS. Memory Area: M100.0 to M105.7 and DB: DB60 with total 20 Words ie from DB60.DBW00 to DB60.DBW38. DB60 is downloaded with total 60 array counts. DB61 is not loaded. DCS is sending the commond data and Receive LED on CP341 is blinking but Trasmitt LED is not blinking at all. So no data on the DCS is visible.

RS422 communication with 4-wire, Full-Duplex is used. The diagnosis buffer data is attached in the attachement. Also the Configuration downloaded in CP-341 is attched.

Please anybody have any idea about this problem. Your response will be appriciate.

Thanks in Advance.
