Scan Processing
Outline of Scan Processing
There are three types of MP940 scan processing: S (system) scans, H (High-
speed) scans, and L (Low-speed) scans. Scan processing segments all S scan
periods into descrete time elements and then executes the S scan as a base
period.
When setting the proportion of assignments into the background within the S
scan period, ensure the "Background Processing Time" for PP processing.
Scan Types
Type Content
S Scan
(System Scan)
Select a base period for scan processing: 0.5, 1.0, 2.0, 4.0ms.
S, H and L scan processing segments all S scan periods into discrete time
elements and then executes the S scan as a base period.
H Scan
(High-speed Scan)
Set the S scan period in integer multiples.
The scan is broken into discrete time elements and executed within the S
scan period.
L Scan
(Low-speed Scan)
Set the S scan period in integer multiples.
The scan is broken into discrete time elements and executed within the S
scan period.
