(2) When the synchronous data is one-word data (analog input values, ana- log output values, built-in I/O, etc.), the other word can be used for gen- eral-purpose data.

5-4-4 Settings

System Setup (Coordinator Module)

The following settings must be made beforehand when using the synchronous data refresh function.

Synchronization between Modules and Sync Cycle Time must be set in the Coordinator Module's System Setup.

Synchronization between Modules

Name	Settings	Default	Description	Auxiliary Area	Enabled
				Flags
Module Settings Tab Page	Sync/Async	Sync	Synchronization	---	At power ON
Sync Mode			between Modules

Sync Cycle Time

Name	Settings	Default	Description	Auxiliary Area	Enabled
				Flags
Module Settings Tab Page	Default (cycle time)	CM cycle time	Sync cycle time	A404.06	At power ON
Sync Cycle Time	(0.1 to 10.0 ms)		(unit: 0.1 ms)	Sync Cycle Time
				Too Long Flag

When the Sync Cycle Time is specified, all Motion Control Modules will syn- chronize with the Coordinator Module cycle time in PROGRAM mode. The specified Sync Cycle Time is enabled in RUN and MONITOR modes, and the Motion Control Module cycle times will change to the set Sync Cycle Time when in these modes.

Synchronous data link bits will be broadcast from each Module at the time specified under Sync Cycle Time.

If an interrupt task 000 is created, it can be used as a regular interrupt task executed each Sync Cycle Time.

When the Sync Cycle Time is on the default setting, the synchronous data link bits are broadcast from each Module each Coordinator Module cycle. The Motion Control Module cycles are synchronous with the Coordinator Module cycle.

Note If the Sync Cycle Time Too Long Flag (A404.06) turns ON in the Coordinator Module, it means that the Motion Control Module cycle time is longer than the Sync Cycle Time. Either change the Sync Cycle Time or check the Motion Control Module ladder program and shorten the Motion Control Module cycle time to less than the Sync Cycle Time.
