No. Name
SD757 Current interrupt priority
Description
• The time period from completion of a scan program until start of
the next scan is stored into SD526 to SD527 (it is measured in
increments of s).
SD526: stores a value in the ms place (storage range: 0 to
65535)
SD527: stores a value in the s place (storage range: 0 to 999)
• This register is cleared to 0 when the mode transfers from
STOP to RUN mode.
• The waiting time specified in the constant scan setting process
is stored into SD528 and SD529 (it is measured in increments
of s).
SD528: stores a value in the ms place (storage range: 0 to
65535)
SD529: stores a value in the s place (storage range: 0 to 999)
• This register is cleared to 0 when the mode transfers from
STOP to RUN mode.
• The execution time of the scan program for one scan is stored
into SD530 and SD531 (it is measured in increments of s).
SD530: stores a value in the ms place (storage range: 0 to
65535)
SD531: stores a value in the s place (storage range: 0 to 999)
• This register is cleared to 0 when the mode transfers from
STOP to RUN mode.
Description
This register stores the enable/disable classification of the
inserted SD card.
This register stores the memory card usage condition.
This register stores the drive 2 storage capacity (unit: 1 K byte).
(Free space value after formatting is stored.)
This register stores the drive 2 storage capacity (unit: 1 K byte).
(Free space value after formatting is stored.)
This register stores the drive 2 storage capacity (unit: 1 K byte).
(Free space value after formatting is stored.)
This register stores the drive 2 storage capacity (unit: 1 K byte).
(Free space value after formatting is stored.)
This register stores the free space value in drive 2 (unit: 1 K byte).
This register stores the free space value in drive 2 (unit: 1 K byte).
This register stores the free space value in drive 2 (unit: 1 K byte).
This register stores the free space value in drive 2 (unit: 1 K byte).
Stores an index for the number of write operations to data
memory currently. However, the index does not equal the actual
number of write operations.
Description
This register stores the interrupt priority of the interrupt program
being executed.
1 to 3: The interrupt priority of interrupt program executed.
0: The interrupt is not executed. (default value)
