Appendix 4 Special Registers
SD600 Memory card
mounting status
SD memory card type This register indicates the type of mounted SD memory cards. S (Initial process
or card inserted)
SD604 SD memory card
usage status
SD memory card usage
status
The status of the SD memory card usage is stored as the following bit
data patterns.
(Being used when turned ON)
b0: Event history
b1: Not used
b2: Data for renewing labels
b3 to b15: Not used
S (Status
change)
SD606 SD memory card
capacity
SD memory card capacity:
the lower digits (unit: k
bytes)
The capacity of the SD memory card is stored in increments of 1k byte
(the amount of free space for a formatted memory card is stored).
S (Initial process
or card inserted)
SD607 SD memory card capacity:
the higher digits (unit: k
bytes)
SD610 SD memory card
free space
SD memory card free space:
the lower digits (unit: k
bytes)
The amount of free space of the SD memory card is stored in increments
of 1k byte.
S (Status
change)
SD611 SD memory card free space:
the higher digits (unit: k
bytes)
SD620 Standard ROM
usage status
Standard ROM usage status The status of the standard ROM usage is stored as the following bit data
patterns.
(Being used when turned ON)
b0: Event history
b1: Not used
b2: Data for renewing labels
b3 to b15: Not used
SD622 Standard ROM
capacity
Standard ROM capacity:
lower (unit: k bytes)
Standard ROM capacity is stored in increments of 1k byte.
(The free space after format is stored.)
S (Initial process)
SD623 Standard ROM capacity:
higher (unit: k bytes)
SD624 Standard ROM free
space
Standard ROM capacity:
lower (unit: k bytes)
Standard ROM free space is stored in increments of 1k byte. S (Status
change)
SD625 Standard ROM capacity:
higher (unit: k bytes)
SD634 Index for the number
of standard ROM
write operations
Index of the number of write
operations up to now
• Indicates the index value for the number of write operations to the
standard ROM up to now (stored as a 32-bit BIN value). However, the
number of write operations is not equal to the index value.
• When the index value exceeds 100000, an error is generated (the
index value is continued to be counted even when it exceeds 100000).
If the index value exceeds 100000, the CPU module must be replaced.
S (Write)
SD635
SD700 Device assignment Number of points assigned
for #
Stores the number of points for device # used in the Motion CPU. S (Initial process)
SD701
SD714 Low speed Motion
setting operation
cycle
Low speed Motion setting
operation cycle
• Stores the set low speed Motion operation cycle in [s] units.
• Except for when low speed operation cycle magnification setting is set
to "Not used", the value of "Motion setting operation cycle (SD523)"
multiplied by the low speed operation cycle magnification setting is
stored.
• When low speed operation cycle magnification setting is set to "Not
used", or a mixed operation cycle setting error is occurring, "0" is
stored.
No. Name Data stored Details Set by

timing)
0: Does not exist
