12. OVERVIEW OF PROCESSING PERFORMED BY THE QnACPU
(6) Low-speed execution monitoring time
This is a timer for monitoring the execution time of low-speed execution type
programs; no default value is set.
To monitor the execution time of an low-speed execution type program, a value can
be set within the range of 10ms to 2000ms in "PLC RAS" in the parameter mode.
(Setting units: 10ms).
If the low-speed scan time exceeds the set low-speed execution monitoring time, a
"PRG TIME OVER" error occurs. The QnACPU however continues its operation.
POINT
The low-speed execution monitoring time is measured in low-speed END
processing.
Because of this, when the low-speed execution monitoring time (t) is set to 100ms,
a "PRG TIME OVER" error occurs if the low-speed scan time measured in low-
speed END processing exceeds 100ms.
