Table12.38 Special register
Explanation
• Program number of program currently being executed is stored as BIN
value.
• Program number of low speed excution type program No. currently
being executed is stored as BIN value.
• Enabled only when SM510 is ON.
• The current scan time is stored into SD520 and SD521.
(Measurement is made in 100 s units. (For the Universal model QCPU,
in 1 s units.))
SD520: Stores the ms place. (Storage range: 0 to 65535)
SD521: Stores the s place. (Storage range: 0 to 900 (For the
Universal model QCPU, storage range is 0 to 999))
(Example) When the current scan time is 23.6ms, the following values are
stored.
SD520 = 23
SD521 = 600
• Stores the scan time of an initial execution type program into SD522 and
SD523.
(Measurement is made in 100 s units. (For the Universal model QCPU,
in 1 s units.))
SD522: Stores the ms place. (Storage range: 0 to 65535)
SD523: Stores the s place. (Storage range: 0 to 900 (For the Universal
model QCPU, storage range is 0 to 999))
• Stores the minimum value of the scan time except that of an initial
execution type program into SD524 and SD525. (Measurement is made
in 100 s units. (For the Universal model QCPU, in 1 s units.))
SD524: Stores the ms place. (Storage range: 0 to 65535)
SD525: Stores the s place. (Storage range: 0 to 900 (For the Universal
model QCPU, storage range is 0 to 999))
• Stores the maximum value of the scan time except that of an initial
execution type program into SD526 and SD527. (Measurement is made
in 100 s units. (For the Universal model QCPU, in 1 s units.))
SD526: Stores the ms place. (Storage range: 0 to 65535)
SD527: Stores the s place. (Storage range: 0 to 900 (For the Universal
model QCPU, storage range is 0 to 999))
• Stores the current scan time of a low speed execution type program into
SD528 and SD529.
(Measurement is made in 100 s units.)
SD528: Stores the ms place. (Storage range: 0 to 65535)
SD529: Stores the s place. (Storage range: 0 to 900)
• Stores the minimum value of the scan time of a low speed execution
type program into SD532 and SD533.
(Measurement is made in 100 s units.)
SD532: Stores the ms place. (Storage range: 0 to 65535)
SD533: Stores the s place. (Storage range: 0 to 900)
• Stores the maximum value of the scan time except that of the first scan
of a low speed execution type program into SD534 and SD535.
(Measurement is made in 100 s units.)
SD534: Stores the ms place. (Storage range: 0 to 65535)
SD535: Stores the s place. (Storage range: 0 to 900)
• Stores the time from the end of a scan execution type program to the
start of the next scan into SD540 and SD541.
(Measurement is made in 100 s units.(For the Universal model QCPU,
in 1 s units.))
SD540: Stores the ms place. (Storage range: 0 to 65535)
SD541: Stores the s place. (Storage range: 0 to 900) (Storage range: 0
to 900 (For the Universal model QCPU, storage range is 0 to 999))
