1)
Mandatory signals (must be provided by the user).
2)
The signal is provided by the control system. Specially the both signals SGND and +5V are provided
by the PCD, if the Profibus configuration is correct.
Port#10: Pins 3, 4, 5, 6 and 8 are insulated from the system. Pin 2 serves as a backlink for Pin 7.
Port#0: This can be used as an alternative only, either the 10-pole terminal block or the 9-pole D-Sub
socket.
