DEVICE EXPLANATION
• Although writing is also allowed in the "refresh range" portion of the link
device range (specified by refresh parameters), the link module's link device
data will be rewritten when a refresh operation occurs.
When writing by link direct device, the same data should also be written to the
CPU module related devices designated by refresh parameter.
[Refresh parameter settings]
• Network No. : 1
