3.2.8 FS0 Operator's Panel
The FS0 operator's panel consists of many key-operated switches,
LEDs, a rotary switch, and other components. The status of each of
key-operated switches and lamps is coded and as many signal lines as
the number of actual switches are not required to connect the
operator's panel to a CNC. PMC management software automatically
codes the status and transfers data.
These operations require only that simple bit images indicating the
switches, LEDs, and other components to be operated by a PMC
ladder program.
