Today, let’s talk about how to interface the EG edge gateway with Keyence KV-7500 series PLCs via the KV TCPprotocol.
Статья, о которой мы говорили ранее:
Как интегрировать шлюз пограничных вычислений EG с General Electric PLC
Как интегрироваться с ПЛК Xinjie по протоколу Modbus RTU
Как взаимодействовать с ПЛК Keyence серии KV-8000 по протоколу MC-3E
Compatible PLC: KV-7500 Series
1. Подключение оборудования
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. Параметры связи с ПЛК
IP:192.168.0.10
Порт: 8501
3. Конфигурация 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: KV TCP
Network Port: Connected to the gateway’s LAN port
Адрес: 192.168.0.10
Порт: 8501
Таймаут соединения: 2000
Таймаут связи: 2000
Время ожидания: 60000
Station ID: 0
Do not use station ID
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. 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. Тестирование
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!
