1.3.4 Communication with remote devices
(1) 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/from the refresh buffer of the master
station at the execution of the END instruction to perform communication with the
remote devices.
(2) When the CPU does not have automatic refresh function (example:
AnA series CPU)
Data is transferred to/from the refresh buffer of the master station directly by
sequence ladder logic to perform communication with the remote devices.
