3.4.1 External Mounting
The multiplexer master and multiplexer slaves are connected to a termination board.
The termination board forwards the signals via screw terminals. The termination board
establishes the connection to the connected multiplexer masters and multiplexer slaves in
parallel or series. This type of mounting is independent of the process control system used and
of any existing control units.
