Explanation
This register stores the current scan time of a low-speed
execution type program.(The time is measured in increments of
100µs.)
SD528: Stores a ms value (storage range: 0 to 65535)
SD529: Stores a µs value (storage range: 0 to 900)
This register stores the minimum scan time of a low-speed
execution type program.(The time is measured in increments of
100µs.)
SD532: Stores a ms value (storage range: 0 to 65535)
SD533: Stores a µs value (storage range: 0 to 900)
This register stores the maximum scan time excluding the time
taken to the first scan of a low-speed execution type program.
(The time is measured in increments of 100µs.)
SD534: Stores a ms value (storage range: 0 to 65535)
SD535: Stores a µs value (storage range: 0 to 900)
Stores the time from the end of a scan program to the start of
the next scan. (The time is measured in increments of 100µs.)
SD540: Stores a ms value (storage range: 0 to 65535)
SD541: Stores a µs value (storage range: 0 to 900)
Stores the time from the end of a scan execution type program
to the start of the next scan. (The time is measured in
increments of 100µs (in icrements of 1µs for the Universal
model QCPU and LCPU).)
SD540: Stores a ms value (storage range: 0 to 65535)
SD541: Stores a µs value (storage range: 0 to 900 (0 to 999
for the Universal model QCPU and LCPU)).
This register stores wait time for constant scan. (The time is
measured in increments of 100µs (in icrements of 1µs for the
Universal model QCPU and LCPU).)
SD542: Stores a ms value (storage range: 0 to 65535)
SD543: Stores a µs value (storage range: 0 to 900 (0 to 999
for the Universal model QCPU and LCPU)).
