TIMERON
The CNC has a timer to be used at will.
It times in seconds and it is enabled and disabled with this mark. It will be enabled (counting)
with TIMERON set high (=1).
To reset and or know its accumulated timing, use the variable: (V.)PLC.TIMER. This variable
is accessible from the PLC program, MDI or interface (any supported application).
PLCREADY
This mark indicates whether the PLC is running (=1) or stopped (=0).
• It must be high (=1) for the CNC to allow moving the axes and turning the spindle.
• If set low (=0), the PLC program stops and an error message is displayed.
NOWAIT
There is a mark for each channel. The mnemonics for each channel are the following.
NOWAITC1 NOWAITC2 NOWAITC3 NOWAITC4
It is applied to channel synchronization. The PLC sets this mark high (=1) to cancel all the
synchronizations with the CNC channel.
For example, with the NOWAITC1 signal set to (=1), the waits programmed in any channel
with the #WAIT, instruction and that refer to a mark of channel 1, they finish immediately and
the program execution resumes.
DISCROSS1
··
DISCROSSn
It is applied to the cross compensation tables defined in the machine parameters. There is
a mark for each table.
The PLC sets the mark to (=1) to disable the table. The DISCROSS1 mark is for table 1,
DISCROSS2 for table 2 and so on.
EXRAPID
There is a mark for each channel. The mnemonics for each channel are the following.
EXRAPIDC1 (can also be programmed as EXRAPID)
EXRAPIDC2 EXRAPIDC3 EXRAPIDC4
If the PLC activates this mark, the CNC channel enables rapid traverse during the execution
of a program for the programmed movements. The behavior of this mark depends on how
parameter RAPIDEN has been set.
The treatment of this signal is similar to the rapid key of the operator panel.
Example of how to know the machining time.
CY1
() = MOV 0 R100
()= CNCWR (R100, PLC.TIMER, M11)
Resets the timer to "0" on power-up.
