Today, let’s talk about how to interface the EG edge gateway with Keyence KV-7500 series PLCs via the KV TCPprotocol.
The article we discussed before:
How to integration EG edge computing gateway with General Electric PLC
How to integration with Xinjie PLC via Modbus RTU protocol
How to interface with Keyence KV-8000 series PLCs via the MC-3E protocol
Compatible PLC: KV-7500 Series
1. Hardware Connection
The KV TCP protocol utilizes Ethernet communication. Therefore, simply ensure the gateway’s LAN port and the Keyence PLC’s IP address are within the same subnet.
| EG8200Mini（LAN） | KV-7500 | |
| IP address | 192.168.0.88 | 192.168.0.10 |
2. PLC Communication Parameters
IP:192.168.0.10
Port: 8501
3. Gateway Configuration
3.1. PLC Connection Settings
Drag a Keyence node from the left panel, double-click to open the settings page, and configure as follows based on the PLC’s communication parameters:
Protocol: KV TCP
Network Port: Connected to the gateway’s LAN port
Address: 192.168.0.10
Port: 8501
Connection Timeout: 2000
Communication Timeout: 2000
Keepalive Time: 60000
Station ID: 0
Do not use station ID
3.2. Data Point Configuration
Enter the data points to be read into the parameter list of the Keyence 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 DM490 and DM492. 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. Testing
Click Deploy and observe that a data point is printed every 2 seconds. Verify that the data point name and corresponding value are returned—communication is successful!
