9 Connector assignment PG-Switch I / II / III
AG Interface
This Interface should be 1:1 connected with the Siemens-PLC, for a correct work of the PG-
Switch. The pins below this text are inputs of the PG-Switch.
The PG-Switch have internally connected aktive receiver and transmitter. The pins 2, 9, 6, 7
must be connected 1:1 with the PLC.
