Variables
13.2.14 PLC related variables
It should be borne in mind that the PLC has the following resources:
(I1 thru I512) Inputs.
(O1 thru O512) Outputs.
M1 thru M5957) Marks.
(R1 thru R499) 32-bit registers.
(T1 thru T512) Timers with a timing count in 32 bits.
(C1 thru C256) Counters with a count in 32 bits.
If any variable is accessed which allows the status of a PLC variable to be read or modified
(I,O,M,R,T,C), block preparation is interrupted and the CNC waits for this command to be executed
in order to restart block preparation.
Read-only variables
PLCMSG
Returns the number of the active PLC message with the highest priority and will coincide with the
number displayed on screen (1··128). If there is none, it returns 0.
Read-and-write variables
PLCIn
This variable allows 32 PLC inputs to be read or modified starting with the one indicated (n).
The value of the inputs which are used by the electrical cabinet cannot be modified as their values
are determined by it. Nevertheless, the status of the remaining inputs can be modified.
PLCOn
This variable allows 32 PLC outputs to be read or modified starting from the one indicated (n).
PLCMn
This variable allows 32 PLC marks to be read or modified starting from the one indicated (n).
PLCRn
This variable allows the status of 32 register bits to be read or modified starting from the one indicated
(n).
PLCTn
This variable allows the timer count to be read or modified starting from the one indicated (n).
PLCCn
This variable allows the counter count to be read or modified starting from the one indicated (n).
(P110=PLCMSG)
It assigns to P100 the number of the active PLC message with the highest priority.
(P110=PLCO 22)
It assigns to parameter P110 the value of outputs O22 through O53 (32 outputs) of the
PLC.
(PLCO 22=$F)
It sets outputs O22 through O25 to "1" and outputs O26 through O53 to "0".
