Read-and-write variables
TIMER
This variable allows reading or modifying the time, in seconds, indicated by the clock enabled by
the PLC. Possible values 0..4294967295.
The CNC will set this value to 0 when changing the software version or when a checksum error
occurs.
PARTC
The CNC has a part counter whose count increases, in all modes except simulation, every time M30
or M02 is executed and this variable allows its value to be read or modified. This value will be between
0 and 4294967295
The CNC will set this value to 0 when changing the software version or when a checksum error
occurs.
KEY
It allows reading the last accepted keystroke or simulating the CNC keyboard assigning the desired
key code to it.
KEYSRC
This variable allows reading or modifying the source of keystrokes, possible values being:
0 = Keyboard.
1 = PLC.
2 = DNC.
The CNC only allows modification of this variable if it is set to "0" or "1".
Once the keystroke simulation is finished, it is advisable to re-enable the CNC keyboard in order
to be able to access the various operating modes of the CNC.
The CNC will assign a value of 0 to this variable on power-up and after pressing [SHIFT]+[RESET].
ANAOn
This variable allows the required analog output (n) to be read or modified. The value assigned will
be expressed in 0.0001 volt units and within ±10 V.
The analog outputs which are free among the sixteen (1 through 16) available at the CNC may be
modified, the corresponding error being displayed if an attempt is made to write in one which is
occupied.
When setting an axis as a DRO axis from the PLC, the analog output becomes free so it can be
written from the CNC or from the PLC.
In the case of analog CAN I/O: See chapter "4 Remote modules (bus CAN with CanOPEN
protocol)" .
CNCRD (KEY, R110, M10)
Loads register R110 with the value of the last key accepted.
To simulate the CNC keyboard from the PLC, follow these steps:
R111=1 R110=0
CNCWR (R111, KEYSCR, M10)
Indicates to the CNC that only keystrokes coming from the PLC must be processed (CNC keyboard
inhibited).
CNCWR (R101, KEY, M10)
It indicates to the CNC that a key has been pressed whose code is indicated in register R101.
CNCWR (R110, KEYSCR, M10)
Process only keystrokes coming from the CNC.
