1. Omron FINS Description
The Ethernet Omron FINS driver allows the FieldServer to transfer data to and from
devices over Ethernet using Omron FINS protocol. The FieldServer can emulate either
a Server or Client.
FINS is an Omron protocol which can be used by a PLC program to transfer data and
perform other services with a remote PLC connected on an Ethernet Network. It can
also be used by remote devices such as PC’s and FieldServer’s to transfer data and
perform other services.
The protocol uses the Ethernet protocol called UDP to carry the FINS messages back
and forth. The UDP protocol is not connection based and reliability is achieved by using
confirmation messages.
This Ethernet Driver can be used to transfer data to and from the Nodes supporting
FINS communications.
