Dreamine.PLC.Omron.Fins 1.0.1

Dreamine.PLC.Omron.Fins

Korean documentation

Omron FINS TCP/UDP PLC adapter for the Dreamine PLC package family.

This package provides FINS TCP/UDP client support and built-in FINS simulator servers for local and PC-to-PC validation.

Features

• Omron FINS TCP client
• Omron FINS UDP client
• FINS TCP simulator server
• FINS UDP simulator server
• Memory area read/write support boundary
• Word read/write diagnostics
• Repeated handshake validation flow
• Timeout and retry support for UDP
• Integration with IPlcClient

Supported simulator test modes

The SampleSmart PLC Protocol page supports:

FinsTcp ↔ FinsTcp
FinsUdp ↔ FinsUdp

The server and client modes must match. A SimulatorTcp, McTcp, or McUdp server cannot be used with a FinsTcp or FinsUdp client.

1PC test

Use this flow for local validation.

Mode: FinsTcp or FinsUdp
Host: 127.0.0.1
Port: 55000
Start Server
Use Client
Connect
Write Words
Read Words
Run Handshake

2PC test

Server PC:

Mode: FinsTcp or FinsUdp
Host: 0.0.0.0
Port: 55000
Start Server

Client PC:

Mode: same as server
Host: server PC IP
Port: 55000
Use Client
Connect
Read/Write or Handshake

Firewall requirement for PC-to-PC tests

Open the inbound port on the server PC.

For TCP:

New-NetFirewallRule -DisplayName "Dreamine PLC FINS TCP 55000" -Direction Inbound -Protocol TCP -LocalPort 55000 -Action Allow

For UDP:

New-NetFirewallRule -DisplayName "Dreamine PLC FINS UDP 55000" -Direction Inbound -Protocol UDP -LocalPort 55000 -Action Allow

Run PowerShell as Administrator. Without these rules, local 1PC tests may pass while 2PC tests fail.

Physical PLC test notice

FINS support is currently validated with the built-in simulator. Physical Omron PLC integration must still be tested.

Before connecting to a real Omron PLC, verify:

• PLC model and Ethernet module support
• FINS TCP/UDP setting
• Port number, commonly configured as 9600 in many FINS environments
• Source and destination node settings
• Network number
• Unit address
• Memory area mapping
• PLC Ethernet module routing settings
• Safe polling interval

FINS/TCP may require device-specific handshake or node configuration. Simulator success does not guarantee physical PLC compatibility without field testing.

Polling and write safety

Do not use 1ms polling against a physical PLC.

Recommended physical PLC values:

• Monitoring: 100ms to 500ms
• UI display refresh: 250ms to 1000ms
• Write: event-driven only
• Handshake stress test: simulator only unless explicitly approved for a real machine

Vendor runtime policy

This package does not include Omron CX-Compolet, SYSMAC Gateway, or any Omron runtime DLL.

This package implements FINS TCP/UDP communication directly. CX-Compolet integration, if needed, must remain in a separate adapter package without redistributing vendor DLLs.

Validation status

Validated:

• 1PC FINS TCP read/write and handshake
• 1PC FINS UDP read/write and handshake
• 2PC FINS TCP read/write and handshake
• 2PC FINS UDP read/write and handshake
• WPF monitor integration

Pending:

• Physical Omron PLC validation
