16.1 PG-MUX-II for Siemens S5
AG Interface
This Interface should be 1:1 connected with the Siemens-PLC, for a correct work of the
Multiplexer.
The pins below this text are inputs of the Multiplexer.
Pin 11, 13 are not connected.
The PG-MUX-II have internally connected active receiver and transmitter. The pins 2, 9, 6, 7
must be connected 1:1 with the PLC.
