The FS0 operators panel is provided with a lot of key switches, LEDs,
rotary switches, etc. For key switches and LEDs, they are coded, and
connected to the CNC with less signal lines than the actual number of
theses signals. The coding and data transfer are executed by the PMC
management software automatically. Therefore, it is only necessary for
the PMC ladder program to operate with the simple bit image for the key
switches and LEDs.
This chapter describes how the Series 16/18 users connect and assign the
key switches and LEDs signal address and their bit image address to the
PMC address.
