Hi,
for master circuit (robot is slave) You should use rack 67 slot 1, and for slave robot devices rack 66 slot 1
If do not use any PLC controller for example then do not use any configuration with rack 67.
For slave You should use:
example: DO 70 - 77 RACK 66/SLOT 1/START PT 1
DO 78 - 85 66/1/9
DO 86 - 93 66/1/17
and etc.....
The same way for DI. Everything depends where do You want start with I/O.
If You do not have then do not use any offsets on profibus.
Next thing - You are not disturbing my time
Any from my sets for profibus was helpfull??
With any question just let me know. I cannot promise that I'll give immediately but anyway I'll try to
