1. Conexión de hardware

Compatible PLC: NX7

The Fins protocol utilizes Ethernet communication. Therefore, it is only necessary to ensure that the LAN port IP address of the gateway and the IP address of the Omron PLC are within the same subnet (Note: In special cases, they may not be on the same subnet, requiring route configuration; consult technical support for details). The IP address allocation for this example is as follows:

EG8200Mini

Omron PLC
IP Address 192.168.250.4 192.168.250.10

3. Configuración de la puerta de enlace

3.1. Configuración de la conexión del PLC

Drag an Omron node from the left panel and double-click to open the settings page. Configure the following based on the PLC’s serial port parameters:

Protocolo: Select Fins

Dirección: Enter the PLC address (e.g., 192.168.250.10)

Puerto: Enter the PLC connection port (e.g., 44818)

Tiempo de espera de la conexión: 2000

Tiempo de espera de comunicación: 2000

Mode: TCP

SIot: 0

3.2. Configuración de los puntos de datos

Enter the data points to be read into the parameter list of the Omron node. Once configured, the PLC data will be automatically retrieved at the specified frequency.

Los puntos de datos suelen proporcionarlos los ingenieros de PLC. Una vez recibida la lista de puntos, rellene los puntos de datos de acuerdo con el formato requerido por la pasarela. Para obtener correspondencia específica, consulte:

3.3. Pruebas

Click Deploy and observe that a data point is printed every 2 seconds. The read data point results are: D100: false, D102: 99. Communication successful!
