FINS commands can be sent from the user’s ladder-diagram program in the
PLC by using the SEND(090), RECV(098), and CMND(490) instructions.
SEND(090): Writes I/O data from the local node to another node.
RECV(098): Reads I/O data from another node to the local node.
CMND(490): Issues FINS commands for controlling operations such as send-
ing and receiving I/O memory data to and from other nodes, reading informa-
tion regarding other nodes, and so on.
The following table shows the specifications for PLC communications using
the SEND(090), RECV(098), and CMND(490) instructions.
