5-4	Synchronous Data Refresh
5-4-1	Outline
		If Sync is set under Synchronization between Modules in the System Setup,
		each Module will broadcast the specified data (2 types data, 4 words max.) to
		the Synchronous Data Link Bit Areas each Coordinator Module cycle or spec-
		ified sync cycle.
		Each other Module receives this data. Every Module can access the synchro-
		nous data for every other linked Module.
		If Synchronization between Modules is set to Sync, the cycle for every Motion
		Control Module will be automatically synchronized to the Coordinator Module
		or specified sync cycle, which enables the use of the synchronous Data Link
		Bit Areas as synchronous data.
		The Synchronous Data Link Bit Area is from CIO 0200 to CIO 0219, with 4
		words allocated to each Module (Coordinator Module and all Motion Control
		Modules).
Sync Cycle Time		When Sync Mode is set, the Sync Cycle Time can be set under Sync Cycle
		Time in the Coordinator Module’s System Setup. (Default: Coordinator Mod-
		ule cycle time. Setting range: 0.1 to 10.0 ms, Unit: 0.1 ms.)
	Note	Set the Sync Cycle Time longer than the longest cycle time among the syn-
		chronized Motion Control Modules.
Synchronous Data		Any of the following data can be set as synchronous data for each Module (4
		words max.)
		• Ladder execution results
		• High-speed counter 1/2 PV
		• Pulse output 1/2 PV
		• Analog input value
		• Analog 1/2 output value
		• Built-in I/O input
5-4-2	Applications
		An example application would be the creation of a virtual axis in any Module
		for all Modules to refer to when synchronizing operation. Another application
		is for the results of ladder program execution to be used as synchronous data.
