1. Ligação do 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:
| Omron PLC | ||
| IP Address | 192.168.250.4 | 192.168.250.10 |
2. Parâmetros de comunicação do PLC
2.1. Ethernet Parameter Settings
2.2. Variable Address
3. Definições da porta de entrada
3.1. Definições de ligação do 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
Endereço: Enter the PLC address (e.g., 192.168.250.10)
Porto: Enter the PLC connection port (e.g., 44818)
Tempo limite de ligação: 2000
Tempo limite de comunicação: 2000
Mode: TCP
SIot: 0
3.2. Configuração do ponto de dados
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.
Data points are typically provided by PLC engineers. Upon receiving the point list, fill in the data points according to the gateway’s required format. For specific correspondence, refer to:

This example reads data from addresses A_MES_Heart and A_MES_Bind_C. In the parameter list, enter the address/name/data type/data length in sequence. Data is read cyclically every 2 seconds, as shown in the figure:
3.3. Ensaios
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!
