The number of points of the device Y currently set is stored as 32-bit
data.
• The number of points of the device M currently set is stored as 32-bit
data.
• The number of points assigned is stored even when the number of
points assigned to M is 32K points or less.
• The number of points of the device B currently set is stored as 32-bit
data.
• The number of points assigned is stored even when the number of
points assigned to B is 32K points or less.
The number of points of the device F currently set is stored as 32-bit
data.
• The number of points of the device D currently set is stored as 32-bit
data.
• The number of points assigned is stored even when the number of
points assigned to D is 32K points or less.
SD480
Motion CPU operation
cycle over count
0: Motion operation cycle
over not occurrence
(Normal)
1 to 65535: Operation cycle
over cumulative count
Stores the count for the motion operation process (including intermodule synchronization process) not completed within the motion
operation cycle.
After exceeding 65535 the count returns to 0 and counts again.
The counts are stored regardless of the "CPU module operation setting
at error detected" RAS setting.
This counter is valid even is inter-module synchronization is not used.
SD484
Fixed scan data
transmission section
over count
0: Fixed scan data
transmission section over
not occurrence (Normal)
1 to 65535: Fixed scan data
transmission section over
cumulative count
Stores the count for the motion operation process not completed by the
fixed-cycle data transmission set in the Multiple CPU synchronous
cycle. After exceeding 65535 the count returns to 0 and counts again.
The counts are stored regardless of the "CPU module operation setting
at error detected" RAS setting.
This counter is valid even is inter-module synchronization is not used.
