Hi,i try to communicate a siemens s7 200 with a maple hmi silver series 520M. I'm able to communicate with my PC via rs485 port with a usb/ppi cable. I transfert with no problem program on the hmi. I made a cable with maple specs founds on the web to communicate PLC/HMI like that:
Maple PLC
5 return --- 2 ground
1 data- --- 8 A (tx-/rx-)
2 data+ --- 3 B (tx+/rx+)
The hmi would not communicate with the plc (PLC no response)so is that any point in the software step 7 to mention a hmi? I've set the infos on easybuider on system parameter . I've tried the two communication port on the hmi, rs232 and rs485 with no success.
Thanks for you help.
