OMRON FINS DESCRIPTION 1
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.
