Executing refresh
Refresh is executed when the CPU module is in RUN and/or STOP (PAUSE) state. For details on the behavior when the CPU
module is in stop error state, refer to CPU module operation upon error detection setting. ( Page 204 CPU module
operation upon error detection setting)
■Behavior during the multiple CPU synchronous interrupt program (I45) execution
If refresh is set to be performed during the multiple CPU synchronous interrupt program (I45) execution, the refresh behavior
when the CPU module is in RUN state varies depending on either of the following conditions. ( Page 363 Multiple CPU
Synchronous Interrupt)
• A program (I45 to IRET) which includes the multiple CPU synchronous interrupt program (I45) exists.
• Event execution type program exists.
The following table lists the refresh behaviors.

*4 Operates with the post-change parameters.
Configurable data
This section lists the configurable data with the refresh settings.
■Maximum number of settings
Maximum of 32 settings can be configured per CPU module for any refresh setting.
■Data number of points
Data number of points can be configured within the number of points assigned to the area (within the send range of the fixed
scan communication area) in increments of two points. Device duplication between multiple setting numbers is not allowed.
