scan time
Current scan
time (ms value)
This register stores the current scan time. (The time is
measured in increments of 100s.) (in increments of 1s for
the Universal model QCPU and LCPU).)
• SD520: Stores a ms value (storage range: 0 to 65535).
• SD521: Stores a s value (storage range: 0 to 900 (0 to
999 for the Universal model QCPU and LCPU)).
Example: When the current scan time is 23.6ms, the
following values are stored:
• SD520 = 23
• SD521 = 600
A value in this register is cleared to "0" when the CPU
module is set to STOP.
