Time：2025-08-20 17:44:46

With the increasing application of Programmable Logic Controllers (PLCs) in industrial automation scenarios, more and more devices can realize remote monitoring and intelligent management, enabling the query and control of devices on smart IoT platforms such as mobile phones and computers. Beckhoff PLC is a type of PLC brand and is used in many factories.

In this regard, Wutong Bolian provides a solution for Beckhoff PLC data acquisition, and transmits the data to the cloud SCADA platform through the MQTT protocol, realizing the SCADA monitoring and efficient management of the production site. This solution is implemented through an industrial intelligent gateway, which is equipped with a variety of IoT communication interfaces, such as Ethernet, RS485, RS232, etc. It can connect to and collect data from Beckhoff PLC, and transmit the data to the cloud SCADA platform via 5G/4G for subsequent data analysis and application.

Implemented Functions

1. It can read and write data from PLCs and production equipment of different brands and types, collect various signals from the industrial site, so as to monitor and control the industrial site.

2. It can present industrial site information in the form of graphics and pictures to facilitate the monitoring of the control process; it can also directly issue instructions to the controller PLC to realize remote control and start-stop operations.

3. It can alarm for emergency working conditions in the production process (such as equipment alarms, environmental abnormalities, etc.), and promptly notify relevant personnel through various means such as software interfaces, emails, short messages, WeChat, and sound and light alarms.

4. It can count and calculate the equipment operation status, real-time data, historical data, fault information and energy consumption data, and generate visual reports for reference by production, management and maintenance personnel.

5. It can provide data for other application software and also receive data, thereby integrating different systems, such as MES systems and ERP systems.

6. It can remotely monitor equipment status and process information on multiple terminals such as mobile phones and computers at the same time, improving management level and work efficiency.
