December 2001 Commands 7 – 85
Execution times for
modules that run as
submit jobs
These modules communicate with other parts of the control software. This
results in inevitable waiting and response times so that execution times
cannot be specified here. If required, determine the execution times by trial.
Some factors that influence response times are:
n CPU load from processing an NC program run
n Load on the file system, for example from copying
n Load on the CPU and the video system, e.g., through PLC windows
Execution times for
modules that run in
the cyclic program
Unless otherwise indicated, the execution time of such modules lies between
10 µs and 100 µs. Unnecessary calls should therefore be avoided (e.g. cyclic
setting of the pulse release, of a soft-key row, etc.).
For some modules the execution times are longer:
Commands without operands Execution times
PLL, PLW, PSL, PSW, PSX, PLX Up to 0.5 µs
A[..., XON[..........] for these commands Up to 0.5 µs
+[..., -[..., X[..........] for these commands Up to 0.5 µs
/[..., MOD[..........] for these commands Up to 0.5 s
0.1 to 1.5 [µs]
==[..., <>[..........] for these commands Up to 0.5 µs
LBL 0 µs
JP, JPT, JPF Up to 0.5 µs
CM, CMT, CMF in their own source module 0.1 to 1.5 µs
CM, CMT, CMF onto a global label 1.0 to 15 µs
EM, EMT, EMF Up to 0.5 µs
IFc, ELSE, UNTILc, WHILEc Up to 0.5 µs
ENDI, REPEAT, ENDW 0 µs
CM with Case (see previous table) 0 µs
ENDC 0 µs
SUBM, RPLY, CAN 1.0 to 15 µs
LX, =X Up to 0.5 µs
INCW, DECW, INCX, DECX Up to 0.5 µs
Module no. Function Time
