Cómo integrar la pasarela EG edge computing con General Electric PLC
Today, let’s talk about how to integration with Xinjie PLC.
Compatible PLC: Xinjie XD Series
1. Conexión de hardware
The Modbus RTU protocol utilizes serial communication. For this example, the PLC model XD3-16T employs RS485 communication. Simply connect the PLC’s 485 port A to the gateway’s A1, and the PLC’s 485 port B to the gateway’s B1.
2. Parámetros de comunicación PLC
2.1. Serial Port Parameter Settings
3. Configuración de la puerta de enlace
3.1. Configuración de la conexión del PLC
Drag a XinJE node from the left panel and double-click to open its settings page. Configure the following based on your PLC’s serial port parameters:
Protocolo: Select Modbus RTU
Serial Port: If connected to A1/B1, select RS485-1
Baud Rate: 19200
Data Bits: 8
Stop Bits: 1
Parity: Even
Tiempo de espera de comunicación: 2000
Series: XD
Identificación de la estación: 1
Format: ABCD
3.2. Configuración de los puntos de datos
Enter the data points to be read into the parameter list of the XinJE node. Once configured, the node will automatically read data from the PLC at the specified frequency.
Data points are typically provided by PLC engineers. After obtaining the point list, fill in the data points according to the gateway’s required format. For specific mapping details, refer to:

This example reads data from addresses M0 and D0. 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. Pruebas
Click Deploy and observe that a data point is printed every 2 seconds. The read data point results are: M0:true, D0:3. Communication successful!
