LOGIC CNC INPUTS AND OUTPUTS.
CNC's physical inputs and outputs are the set of system inputs and outputs that are governed
by the PLC and communicate with the outside world through CNC connectors.
The CNC also has a number of logic inputs and outputs to exchange the internal data with
the marks and registers of the PLC. This way, the PLC has access to some internal CNC
data. Each of these logic inputs and outputs may be referred to using its associated
mnemonic. The mnemonics that begin with a "_" sign indicate that the signal is active low
(0 V).
CNCREADY _ALARM
AUXEND _EMERGEN
MANUAL _STOP
The CNC's logic outputs or PLC consulting signals are grouped into:
• General consulting signals.
• Axis consulting signals.
• Spindle consulting signals.
• Consultation signals of the independent interpolator.
• Tool manager consulting signals.
• Keystroke consulting signals.
The CNC's logic inputs or signals that may be modified via PLC are grouped into:
• General modifiable signals.
• Axis modifiable signals.
• Spindle modifiable signals.
• Modifiable signals of the independent interpolator.
• Tool manager modifiable signals.
• Keystroke modifiable signals.
Abbreviations used in this chapter.
(=0) Low logic level.
