Omron CS1W-RPT01 Benutzerhandbuch

The FINS communications service is a communications protocol developed
by OMRON for FA control devices. It can be used for reading from and writing
to PLC memory, or for controlling various operations, without having to create
a user’s program at the PLC. The FINS communications service has its own
independent address system which does not rely on the actual network
address system, so it can carry out communications in the same way regard-
less of whether the PLC at the local node is on a Controller Link Network or
some other FA network (e.g., SYSMAC NET or SYSMAC LINK). For details
on FINS commands, refer to the FINS Commands Reference Manual (W227).

FINS commands can be sent by using the CMND instruction with a CVM1,
CV-series, CS/CJ-series, or CQM1H-series PLC. The following diagram
shows the data format for sending FINS commands and receiving responses.
The data that is sent and received is all hexadecimal unless otherwise noted.
