CC-Link IE Field Network Synchronous
Communications
This carries out synchronous communications with the slave station using the synchronization cycle specified in the master
station.
This product operates as a master station using the CC-Link IE Field Network synchronous communication function, and
carries out link scanning for each cycle in the synchronization cycle, and synchronized control of slave stations.
Additionally, for networks with the product as the master station, connections are possible to slave stations that do not support
synchronous communications, as well as to those not set for synchronous communications. Slave stations not used for
synchronization operate in a non-synchronous manner.
Network synchronous communication settings of this product
The network synchronization cycle of this product can be configured automatically or manually.
Set the synchronization cycle of this product for "Network Synchronous Communication" under "Required Settings". (
Page 187 CC-Link IE Field Network Parameters List)
■Automatic setting
To set a synchronization cycle automatically, select "Auto setting" in "Synchronization Cycle Setting Method".
The optimal synchronization cycle required for the number of slave connections and number of cyclic assignment points is
configured automatically when this product starts.
The synchronization cycle is selected from 1 ms, 2 ms, or 4 ms, and the set value can be confirmed in the link special register
"synchronous communication cycle settings value" (SW01EA to SW01EB).
■Manual setting
To set a synchronization cycle manually, select "Manual setting" in "Synchronization Cycle Setting Method".
Slave station network synchronization communication settings
To synchronize a slave station with the master station, browse to "Network Configuration Settings", and then set "Network
synchronous communication settings" of the slave station to be synchronized to "Synchronize". ( Page 195 Network
Configuration Settings)
Precautions
■To use this product as a master station
If any one of the following value is set for "Synchronization Cycle Manual Setting" when this product is used as a master
station, the CC-Link IE Field Network synchronous communication function is not available. (Page 193 Required settings
(if master station is selected by station type))
• 0.888 ms
• 1.777 ms
• 3.555 ms
For a product which does not support the CC-Link IE Field Network synchronous communication function, a link scan cycle is
set for "Manual configuration of synchronization cycle". Therefore, for a slave station which operates within the range above,
set "Do not Synchronize" for "Network Synchronous Communication Setting. "(Page 195 Network Configuration Settings)
■If using the product as a local station
For the product which is used as a local station, the CC-Link IE Field Network synchronous communication function is not
available. When using this product as a local station, do not set "Synchronize" for "Network Synchronous Communication" of
the slave station to be synchronized in "Network Configuration Settings". (Page 195 Network Configuration Settings)
