SEQUENCE SCAN SYNCHRONIZATION
SAMPLING FUNCTION
RnPCPU
RnCPU RnENCPU
(Process)
Data of the CPU module are collected when each module synchronizes data with the sequence scan of the CPU module.
The modules which can synchronize and collect with sequence scan are as follows:
• MES interface module (high-speed access)
• High speed data logger module (high-speed collection)
• C intelligent function module (data sampling in sequence scan)
The following table lists the number of modules that can execute this function and the total number of points that can be
collected for a CPU module.
Item
Number of executable modules
Total number of collectable points
For details on the function using the sequence scan synchronization sampling function and collectable data for each module,
refer to the manual for the module used.
( Manual for the module used)
Precautions
Use points in 8K-point increments to use all of the total number of points that can be collected.
The points are assigned in 8K-point increments as follows:
• 6K points used  8K points to be assigned
• 9K points used  16K points to be assigned
