Explanation
• Stores the minimum value of the scan time into SD524 and SD525.
(Measurement is made in 100 s units.)
SD524: Stores the ms place. (Storage range: 0 to 65535)
SD525: Stores the s place. (Storage range: 0 to 900)
• Stores the maximum value of the scan time into SD526 and SD527.
(Measurement is made in 100 s units.)
SD526: Stores the ms place. (Storage range: 0 to 65535)
SD527: Stores the s place. (Storage range: 0 to 900)
• Stores the time from when the scan program ends until the next scan
starts into SD540 and SD541.
(Measurement is made in 100 s units.)
SD540: Stores the ms place. (Storage range: 0 to 65535)
SD541: Stores the s place. (Storage range: 0 to 900)
• Stores the wait time for constant scan setting into SD542 and SD543.
(Measurement is made in 100 s units. (For the Universal model QCPU,
in 1 s units.))
SD542: Stores the ms place. (Storage range: 0 to 65535)
SD543: Stores the s place. (Storage range: 0 to 900 (For the Universal
model QCPU, storage range is 0 to 999))
• Stores the cumulative execution time of a low speed execution type
program into SD544 and SD545.
(Measurement is made in 100 s units.)
SD544: Stores the ms place. (Storage range: 0 to 65535)
SD545: Stores the s place. (Storage range: 0 to 900)
• Cleared to 0 after the end of one low speed scan.
• Stores the execution time of a low speed execution type program during
one scan into SD546 and SD547.
(Measurement is made in 100 s units.)
SD546: Stores the ms place. (Storage range: 0 to 65535)
SD547: Stores the s place. (Storage range: 0 to 900)
• Stored every scan.
• Stores the execution time of a scan execution type program during one
scan into SD548 and SD549.
(Measurement is made in 100 s units.)
SD548: Stores the ms place. (Storage range: 0 to 65535)
SD549: Stores the s place. (Storage range: 0 to 900)
• Stored every scan.
• Stores the execution time of a scan program during one scan into
SD548 and SD549.
(Measurement is made in 100 s units. (For the Universal model QCPU,
in 1 s units.))
SD548: Stores the ms place. (Storage range: 0 to 65535)
SD549: Stores the s place. (Storage range: 0 to 900 (For the Universal
model QCPU, storage range is 0 to 999))
• Stored every scan.
• Sets I/O number for module that measures service interval.
• Stores the service interval for the module specified in SD550 into SD551
and SD552 when SM551 is turned ON.
(Measurement is made in 100 s units.)
SD551: Stores the ms place. (Storage range: 0 to 65535)
SD552: Stores the s place. (Storage range: 0 to 900)
