Wiring Method - Mitsubishi Electric FR-E5NC Instruction Manual

(4) 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.
(5) 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.
