Connection of the bus wiring
The inbound bus wiring is connected to terminals 1A
and 1B of the Profibus connector. The continuing bus
wiring for the next device in line should be connected to
terminals 2A and 2B.
If there are no subsequent devices in the line then
the bus wiring must be terminated with a resistor (switch
to ON).
With the switch set to ON terminals 2A and 2B are
switched off for further continuing bus wiring.
