6.13.3 Scan time measurement
Note1
(1) Definition
This function displays the processing time of set program section during ladder monitoring.
The time required for the subroutine and interrupt programs can be measured.
The time required for the subroutine and interrupt programs can be measured.
(2) Range specification of scan time measurement
There are following two types for specifying a scan time measurement range.
• Setting on the ladder monitor screen
• Setting on the scan time measurement screen
• Setting on the scan time measurement screen
(3) When the subroutine program call instruction is in the measurement range
When the subroutine program call instruction (CALL) is in the range of scan time measurement, the scan time
includes the time required for processing a subroutine program.
includes the time required for processing a subroutine program.
(4) When interrupt programs/fixed scan execution type programs are executed in
the scan time measurement range
The execution time of interrupt programs and fixed scan execution type programs are added.
