How to integration EG edge computing gateway with the General Electric PLC
Today, let’s talk about how to integrate with Xinjie PLC.
Compatible PLC: Xinjie XD Series
1. Подключение оборудования
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. Параметры связи с ПЛК
2.1. Serial Port Parameter Settings
3. Настройки шлюза
3.1. Настройки подключения ПЛК
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:
Протокол: Select Modbus RTU
Последовательный порт: If connected to A1/B1, select RS485-1
Скорость передачи данных: 19200
Биты данных: 8
Стоп-биты: 1
Паритет: Even
Таймаут связи: 2000
Series: XD
ID станции: 1
Format: ABCD
3.2. Конфигурация точки данных
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. Тестирование
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!
