Today, let’s talk about how to interface the EG edge gateway with AB PLC via PCCC protocol.
The article we discussed before:

1. Hardware Connection
Compatible PLC: AB SLC 5/05
The PCCC protocol utilizes Ethernet communication. Therefore, simply ensure the gateway’s LAN port and the AB PLC’s IP address are within the same subnet.
2. PLC Communication Parameters

3. Gateway Settings
3.1. PLC Connection Settings
Drag an AllenBradley node from the left panel, double-click to open the settings page, and configure as follows based on the PLC’s network port parameters:
Protocol: Select PCCC
Address: Enter the PLC address (e.g., 192.168.0.59)
Port: Enter the PLC connection port (e.g., 44818)
Connection Timeout: 2000
Communication Timeout: 2000
3.2. Data Point Configuration
Enter the data points to be read into the parameter list of the Allen-Bradley 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 address F8:1. In the parameter list, enter the address/name/data type/data length sequentially. The data is read cyclically every 2 seconds, as shown in the figure:
3.3. Testing
Connect to the debugging node, click Deploy, and observe that a data point is printed every 2 seconds. The read data point result is:
{F8:1:42669}. Communication successful!
