LOGIC CNC INPUTS AND OUTPUTS.
3
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.); the rest of the signals
are active high.

AUXEND _EMERGEN

Specific signals for a multi-channel system.
Here is a summary of the specific signals of a multi-channel, multi-spindle and/or multimagazine
system. Refer to the installation manual for further detail about each one of them.
The PLC has more signals, e.g. the general signals of the CNC, of the axes, of the keys, etc.
but since they have nothing to do with configuring a multi-channel system, they are not
mentioned in this documentation. Refer to the installation manual for further detail about each
one of them.
The specific logic signals for configuring a system with channels are grouped as follows:
General signals.
Signals related to the –M– auxiliary functions.
Signals related to the –H– auxiliary functions.
Channel synchronizing signals.
The specific logic signals for configuring a system with several spindles are grouped as
follows:
Signals related to the –S– auxiliary functions.
Spindle signals.
The specific logic signals for configuring a system with several tool magazines are grouped
as follows:
Tool manager signals.
