Omron Master – READ ONLY – using FINS Commands- UDP and RS232

OmronFins implements communication with CS/CJ/CP-series CPU Unit or NSJ devices that are compatibles with FINS. It operates as a Master on UDP or serial networks. The communications blocks are dynamically created according to the pooling cycle defined on the AccessType for each Device Point.

Summary Information

Communication Driver Name: OmronFins

Implementation DLL: T.ProtocolDriver.OmronFINS.dll

Protocol: FINS protocol

Interface: UDP and Serial

Equipments supported: CS/CJ/CP-series CPU Unit or NSJ Controller

Tested Equipment: SYSMAC CJ2M CPU34 and CPU35 using UDP/FINS

Supported Operands

Operand	Read	Write	Data Type	Address size

Channel Configuration

Protocol Options

Mode: Determines the compatible equipment:

CS1: CS/CJ series compatible
CV: CV/CVM1 series compatible

Network: Represents the FINS network. This information is related to the Master

Node: Represents the computer Node in the FINS network. If the number 0 is specified, the driver assumes the last octet of the IP Address as the Node number (for UDP Interface)

Ignore Non Fatal Error: Indicates the driver's behavior when the PLC returns a non fatal error status of 64:

True: If it returns a Success with the 64 error code, set the tag quality to GOOD
False: If it returns a Failed with the 64 error code, set the tag quality to BAD

Node Configuration

PrimaryStation Configuration

Serial channels:

Station syntax: <Network>;<Node>;<Unit Id>

Where:

<Network> = Represents the FINS network where the device is located
<Node> = Represents the device Node number in the FINS network
<Unit Id> = Represents the Device ID in the FINS network

E.g.: 0;1;0

UDP channels:

Station syntax:<IP address>;<Port>;<Network>;<Node>

Where :

<IP address> = The IP address of the device in the network
<Port> = The UDP port where the device is listening (default is 9600)
<Network> = Represents the FINS network where the device is located
<Node> = Represents the Device Node number in the FINS network

E.g.: 192.168.1.101;9600;1;0

Note

When using multiple nodes, the UDP port must be different for each Node.

Point Configuration

The syntax for the OmronFins communication points is: <Memory Area>:<Address>

For more information about the valid operands, see Supported Operands.

E.g.:

CA:0 Memory Area = CA, Address = 0
CIO:20 Memory Area = CIO, Address = 20
EM0:1 Memory Area = Extended Memory 0, Address = 1
EM6:1 Memory Area = Extended Memory 6, Address = 1

Troubleshoot

The status of the driver's execution can be observed through the diagnostic tools, which are:

• Trace window
• Property Watch
• Module Information

The above tools indicate if the operations have succeeded or have failed. A status of 0 (zero) means communication is successful. Negative values indicate internal driver errors, and positive values indicate protocol error codes.
