Last week, we created few articles focus on the CNC gateway integration with CNC machines. In this tutorial, we will focus on EG series edge computing gateway with PLCs. We hope this proves helpful.
Today, let’s talk about how to integration with General Electric PLC.
1. Hardware Connection
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 Communication Parameters
Provided by the PLC engineer.
3. Gateway Configuration
3.1. PLC Connection Settings
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
Address: Enter the PLC address (e.g., 192.168.0.59)
Port: Enter the PLC connection port (e.g., 18245)
Connection Timeout: 2000
Communication Timeout: 2000
3.2. Data Point Configuration
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.
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 mapping details, refer to:

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
Click Deploy. Observe that data is printed every 2 seconds. The read data point results are: { R1: 111, R3: 222.14 }. Communication successful!
