Today, let’s talk about how to interface the EG edge gateway with Keyence KV-8000 series PLCs via the MC-3E protocol.
Compatible PLC: KV-8000 Series
1. Подключение оборудования
The MC-3E 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-8000 | |
| IP address | 192.168.1.100 | 192.168.1.1 |
2. Параметры связи с ПЛК
IP: 192.168.1.1
Порт: 5000
3. Настройки шлюза
3.1. Настройки подключения ПЛК
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:
Протокол: MC-3E
Network Port: Connected to the gateway’s LAN port
Адрес: 192.168.1.1
Порт: 5000
Таймаут соединения: 2000
Таймаут связи: 2000
Station ID: 0
Network ID: 0
Binary: √
3.2. Конфигурация точки данных
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. Upon receiving the point list, fill in the data points according to the gateway’s required format. For specific correspondence, refer to:

This example reads data from multiple addresses such as DM00500 and DM00722. In the parameter list, enter each entry in the following order: Address/Name/Data Type/Data Length. The data is read cyclically every 2 seconds, as shown in the diagram:
3.3. Тестирование
Click Deploy and observe that a data point is printed every 2 seconds. Verify that the returned data point name and corresponding value appear—communication is successful!
