We tried to connect a Mitsubishi A2NCPU to an OP170B from Siemens with the RS422 serial interface, but without succes.
Here you can see how we configured the OP170B:
We made a TAG D100 (integer) and setted it in the mitsubishi with the value 546, so we expect to see this on the OP170B, but we only see ######, so we have no connection, we think.
Connection on RS422 (mitsubishi side):
SDA on pin 9
SDB on pin 4
RDA on pin 8
RDB on pin 3
SG on pin 5
Any help would be great
Thanks in forward,
Kind Regards,
Combo
