NOTE
• When the CPU has automatic refresh function (example: QnA series CPU)
When the END instruction is executed by the programmable controller CPU, the buffer memory is automatically
refreshed to enable communication with a remote device.
• When the CPU does not have automatic refresh function (example: AnA series CPU)
Sequence ladder logic is configured to perform direct communication with the buffer memory of the master station and
to enable communication with a remote device
