Omron FINS PLC Tag

Introduction

The Omron FINS PLC Tag PLC Device Tag Icon represents a logical link to an Omron PLC using the FINS protocol.

Configuration Properties

The Omron FINS PLC Tag supports the configuration properties of the Omron Device, plus these additional configuration properties:

Property Type Version Description
Channel Reference 1.0 The Omron Serial Communication Channel or Omron TCP/IP Communication Channel or Omron UDP/IP Communication Channel to the device.
CModeUnit USINT 1.0 If the device is connected to a serial channel, this is the Unit number used in the Host Link outer frame.
BridgeMode BOOL 1.0 True if bridge communications mode is used. False if bridge mode is not used.
NetworkNumber USINT 1.0 The destination network address of the device (ignored if BridgeMode is False).
NodeNumber USINT 1.0 The destination node address of the device (ignored if BridgeMode is False).
UnitNumber USINT 1.0 The destination unit address of the device.

Comments

When communicating on serial links, you can use bridged mode or non-bridged mode. In bridged mode, you can use the directly connected PLC as a gateway to communicate with other PLCs on a network. In non-bridged mode, you can only communicate with the directly connected PLC. Bridged mode messages are 12 bytes longer than non-bridge mode messages, which imposes a slightly higher overhead on the serial communication channel.

Set the BridgeMode property to TRUE to use bridge mode. Set the BridgeMode property to FALSE to use non-bridge mode. The BridgeMode property is ignored if the device is associated with an Omron TCP/IP Channel or an Omron UDP/IP Channel.

Tag Commands

The Omron FINS PLC Tag supports the tag commands of the Omron PLC Tag.

Example Configuration

This is an example of an Omron PLC using FINS over Host Link (serial) protocol at unit address 0, communicating via a serial channel called ".RemotePlant":

PropertyValue
Channel.RemotePlant
CModeUnit0
BridgeModeFalse
NetworkNumber0
NodeNumber0
UnitNumber0

This is an example of an Omron PLC using FINS over UDP/IP at network address 3, node address 1, communicating via a UDP/IP channel called ".LocalPlant":

PropertyValue
Channel.LocalPlant
CModeUnit0
BridgeModeTrue
NetworkNumber3
NodeNumber1
UnitNumber0
