CNC-PLC COMMUNICATION.
With the data exchange between the CNC and the PLC, it is possible to:
• Control the logic CNC inputs and outputs in peripheral mode using specific PLC marks
and registers.
• Transfer auxiliary M, H and S functions from the CNC to the PLC.
• Generate messages and errors at the CNC using PLC marks.
• Read and modify internal CNC variables from the PLC.
• Access all PLC resources from any part-program.
• Monitor PLC resources on the CNC screen.
Abbreviations used in this chapter.
–M– and –H– functions with channels.
The M and H functions are exchanged by channel. When using several channels, the marks
and registers of these functions must indicate the channel number they refer to. If no channel
number is indicated, the marks and registers refer to the first channel.
–S– functions with multiple spindles.
The exchange of S functions is independent from the channel. When using several spindles,
the marks and registers of these functions refer to the spindle number. The spindle number
is determined by its logic number.
(=0) Low logic level.
(=1) High logic level.
