I have a faulty E/R Module 6SC6901-0VR0.
My firm has many good 6SN1145-1BA02-0CA0 in stock.
The device bus connectors of both modules look the same.
Unfortunately I have no description about the device bus connection ( pin out)
Can you switch a 6SC6901-0VR05 for a 6SN1145-1BA02-0CA0? Are the two device buses equal?
Has anybody documents about the device bus?
Many thanks in advance
