Come integrare il gateway di edge computing EG con General Electric PLC
Today, let’s talk about how to integration with Xinjie PLC.
Compatible PLC: Xinjie XD Series
1. Connessione 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. Parametri di comunicazione del PLC
2.1. Serial Port Parameter Settings
3. Gateway Settings
3.1. Impostazioni di connessione 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:
Protocollo: Select Modbus RTU
Serial Port: If connected to A1/B1, select RS485-1
Baud Rate: 19200
Data Bits: 8
Stop Bits: 1
Parity: Even
Timeout di comunicazione: 2000
Series: XD
ID stazione: 1
Format: ABCD
3.2. Configurazione del punto dati
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.
I punti dati sono in genere forniti dai tecnici dei PLC. Dopo aver ottenuto l'elenco dei punti, compilare i punti dati secondo il formato richiesto dal gateway. Per dettagli specifici sulla mappatura, consultare:

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. Test
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!
