4.11 AFC1100 BUS Unit (Optional).
The function of the AFC1100 BUS unit is to simplify the wiring of the PLC I/O lines to a
multi-Axis system. The I/O from each Axis unit (each I/O bus may have up to 20 lines) can be
connected to an AFC1100 BUS unit. All AFC1100 BUS units are connected in parallel mode
through ribbon cables, with only one AFC1100 bus unit physically wired to the PLC.
4.11.1 AFC1100 BUS Unit wiring (example).
In this example only the Bypass input signal has to be connected directly from the PLC to the
each Axis unit. The input control lines from the PLC to one of the AFC1100 BUS units are
connected in parallel. The output signals (fastening results) of all Axis units are in a "*OR"
method. Thus a single output BUS is created with the information from all spindles.
*OR wiring means several lines connected to the same point. If all lines are OFF the result
will be OFF, but will change to ON if at least one of the lines is ON.
