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

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.
