(b) Writing to a link device
An area within the link device address specification range and within the own station send range and outside
the link refresh range can be specified.
Remark
● When an address within the link refresh range is specified (for writing)
Although data are written at the time of the instruction execution, after that, the link device of the CC-Link IE Controller
Network module is overwritten with the device data of the CPU module by link refresh.
Therefore, write the same data to the CPU module device as well as accessing directly to the link device.
