PLC Parameters
6.9 PLC Parameters
WDGPRG (P0)
Indicates the Watchdog time-out period for the main PLC program.
WDGPER (P1)
Indicates the Watch-Dog time-out period for the periodic module of the PLC.
USER0 (P2) . . . USER23 (P25)
Parameters "USER0" through "USER23" do not mean anything to the CNC.
They could contain the type of information that the OEM may find necessary to customize this
machine, such as: Information about the type of machine, PLC program version, etc.
This information can be accessed from the PLC program by means of the "CNCRD" high-level
instruction.
CPUTIME (P26)
This parameter indicates the time the system CPU dedicates to the PLC.
The sampling period is determined by the general parameter LOOPTIME (P72). Hence, for a
sampling period of 4 msec. and a CPUTIME=0, the system CPU dedicates 0.2 millisecond every
8 samplings (thus, 32 milliseconds) to the PLC.
Possible values
Integers between 0 and 65535 ms.
Default value: 0
Possible values
Integers between 0 and 65535 ms.
Default value: 0
Possible values
USER0(P2) - USER7(P9)
Integer numbers between 0 and 255.
USER0(P10) - USER7(P17)
Integer numbers between 0 and 65535.
USER0(P18) - USER7(P25)
Within ±99999.9999 mm or ±3937.00787 inches.
Default value: 0
Value Meaning
0 0.2 ms every 8 samplings.
1 0.2 ms every 4 samplings.
2 0.2 ms every 2 samplings.
3 0.2 ms every sampling.
4 0.4 ms every sampling. With LOOPTIME = 3, 4, 5 or 6
5 0.6 ms every sampling. With LOOPTIME = 3, 4, 5 or 6
6 0.8 ms every sampling. With LOOPTIME = 4, 5 or 6
7 1 ms every sampling. With LOOPTIME 5 or 6.
8 1.2 ms every sampling. With LOOPTIME = 6
Default value: 0
