CNC to PMC Communication
The basic components of the CNC to PMC
communication interface are shown in
•
The CNC controls axis positioning, internal
I/O, program storage/execution, and
communication with the PMC.
When program data is input (via MDI, Mem-
ory, or Tape) the CNC processes the data on
several levels and assigns the data as either:
CNC (Control side) data – like axis positioning
and G code processing.
PMC (Machine side) data – like M, S, or T
code processing.
CNC data is processed by the CNC’s soft-
ware and internal communication system via
the F-BUS. PMC data is sent, via the F-BUS,
to the PMC for processing.
•
Communication signals between and within the CNC and PMC are
called DI (data input) and DO (data output) or I/O (Input/Output)
signals.
4.4.2
PMC to MT Communication
The basic components of the PMC to MT communication interface include
the; PMC, I/O Link, I/O Rack, and MT, as shown in
When data is received from the CNC the PMC:
1. Determines the software area the data pertains to.
2. Sends the data to the proper area of the machine control software.
3. Processes the data. Data processing is determined, affected, and
monitored by the inputs being received from the MT or related
components.
4. Sends an output signal (FIN (finished) signal) allowing the CNC to
resume automatic operation.
Machine functions are controlled by DO signals from the PMC to the MT
and Machine status is monitored via DI signals from the MT to the PMC.
