Following our CNC machine integration guides, we are launching a new tutorial series for the EG Edge Gateway.
This session covers the step-by-step process of interfacing with General Electric PLCs via SRTP protocol. Whether you are handling data acquisition or edge control, this guide has you covered.
1. Hardwareverbinding
The SRTP protocol communicates via Ethernet ports. Therefore, simply ensure the gateway’s LAN port and GE-General Electric PLC share the same subnet.
2. PLC-communicatieparameters
Provided by the PLC engineer.
3. Gateway Configuration
3.1. PLC-verbindingsinstellingen
Drag a GE node from the left pane, double-click to open the settings page, and configure as follows based on the PLC’s serial port parameters:
Protocol: Select SRTP
Adres: Enter the PLC address (e.g., 192.168.0.59)
Haven: Enter the PLC connection port (e.g., 18245)
Time-out verbinding: 2000
Time-out communicatie: 2000
3.2. Configuratie gegevenspunt
Enter the data points to be read into the parameter list of the GE node. Once configured, the PLC data will be automatically retrieved at the specified frequency.
Datapunten worden meestal geleverd door PLC-engineers. Na ontvangst van de puntenlijst vult u de gegevenspunten in volgens het vereiste formaat van de gateway. Raadpleeg voor specifieke details over de toewijzing:

This example reads data from addresses R1 and R3. 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
Klik Implementeren. Observe that data is printed every 2 seconds. The read data point results are: { R1: 111, R3: 222.14 }. Communication successful!
