1) Set write data in "SD."
2) When "REQ" (write request) of the R_WRITE FB is set on, a port is opened to the target station.
3) When the connection is established, the self station issues a write request of the internal memory to the target station by
a loader command via Ethernet.
3) The target station returns a write completion response.
4) When the self station receives the response, "DONE" (write end) of the R_WRITE FB is set on for one scan.
Notes:
When data is not written normally (no response is returned from the target node or the status code of the response is not "00"),
"ERROR" (write error) is set on for one scan. In this case, turn "REQ" (write request) to off and then on again, and reissue a
write request.
