Appendix 9 Processing Time
■Memory dump function
The execution of the memory dump function results in an increase in the scan time. The increase in scan time can be
calculated by the following formula.
Increase in scan time [s] = (KM1  Number of points
*1
) + KM2
*1 This indicates the total number of points (total number of words) of devices that are set in the device area, file storage area, and refresh
data register area. (unit: K words).
■Real-time monitor function
The execution of the real-time monitor function results in an increase in the scan time. The increase in scan time can be
calculated by the following formula.
Increase in scan time [s] = KM1 + (KM2  Number of points of word device) + (KM3  Number of points of bit device)
