"Control & Communication Link system master/local module" on the main or extension base unit having
the PLC CPU used as the master station.
(2) Inverter side
Mount the option (FR-A7NC) on the inverter.
(3) Connect the PLC CC-Link unit master station and the terminal block supplied with the FR-A7NC with

REMARKS
When the CPU has automatic refresh function (example: QnA series CPU)
Through communication with the corresponding devices using sequence ladder logic, data is automatically
transferred to the refresh buffer of the master station at the execution of the END instruction to perform
communication with the remote devices.
When the CPU does not have automatic refresh function (example: AnA series CPU)
Data is transferred to the refresh buffer of the master station directly by sequence ladder logic to perform
communication with the remote devices.
