With the arrival of the Industry 4.0 era, industrial automation and smart manufacturing have become important means for enterprises to enhance their competitiveness. In this process, the PLC (Programmable Logic Controller)—as the core control device in automated production—has seen its performance and data transmission reliability become especially critical.

However, many early-generation PLC devices relied primarily on serial communication, which creates compatibility issues with the Ethernet communication widely adopted in modern industry. To address this challenge, WideIOT offers PLC serial-to-Ethernet data acquisition gateways, serving as an important bridge connecting traditional PLC devices with modern industrial IoT platforms.

A PLC serial-to-Ethernet data acquisition gateway is an IoT device capable of converting serial communication from PLC equipment into Ethernet communication—enabling seamless integration between PLC devices and modern industrial IoT platforms. It not only supports protocol parsing and conversion for mainstream industrial PLC devices, but also collects PLC production data in real time and accurately, transmitting it quickly and reliably to host software or cloud platforms.

Features and Functions

Serial-to-Ethernet Conversion – Through a built-in protocol conversion module, the gateway converts serial data from PLC devices into Ethernet data, enabling communication with Ethernet-based host systems or cloud platforms—greatly improving data transmission efficiency and stability.

Multi-Protocol Support – Since PLC devices from Siemens, Mitsubishi, Omron, Schneider, Delta, Inovance, and other brands often use their own communication protocols, the gateway provides a rich protocol library—delivering technical support for parsing and data acquisition across multiple PLC protocols.

Flexible Connectivity Options – The gateway supports both serial-to-Ethernet communication and 5G/4G/Wi-Fi connectivity, enabling real-time communication with WideIOT Cloud, enterprise private clouds, and third-party cloud platforms such as Baidu Cloud, Alibaba Cloud, and Huawei Cloud.

Edge Computing – The gateway performs local preprocessing of raw data—including intelligent acquisition, data filtering, alarm calculation, change-triggered actions, formula-based computation, and grouping strategies—improving data transmission efficiency and security.

Remote Monitoring and Management – Through PCs or mobile devices, users can remotely monitor and manage PLCs and their subordinate control devices—accessing equipment operating parameters, fault alerts, and other information, and performing remote control and remote maintenance operations.
