In smart manufacturing facilities, Programmable Logic Controllers (PLCs) are essential for automated production. They monitor and control a wide range of equipment—such as robots, sensors, actuators, and more—across the factory floor. PLC smart gateways bridge PLCs with host systems or cloud platforms, enabling seamless data exchange and connectivity. This allows factories to achieve real-time production monitoring and management, with instant visibility into equipment status, alarm events, production data, and other critical information from anywhere.

WideIOT's PLC smart gateways support protocol parsing and data acquisition from major PLC brands, including Siemens, Mitsubishi, Omron, Schneider, Delta, and Inovance. Data is transmitted to local host systems or cloud platforms via 5G/4G/Wi-Fi/Ethernet, with encrypted transmission and edge computing capabilities to ensure data security and integrity. The gateways also enable remote control and remote maintenance of PLCs.

System Functions

Data Acquisition and Transmission – Collects PLC data and transmits it to host systems or cloud platforms (via 5G/4G/Wi-Fi/Ethernet), with visualization processing for convenient analysis and decision-making.

Fault Alerts and Notifications – Continuously monitors PLC operating status. When anomalies—such as parameter deviations—are detected, the system sends timely notifications to designated personnel via WeChat, SMS, or email for prompt resolution and maintenance.

Remote Monitoring and Control – Managers can view real-time equipment operating status and parameters through SCADA-style dashboards, and issue parameter adjustments or control commands remotely. Abnormal conditions can be quickly managed and resolved.

Data Security and Protection – The gateways incorporate robust security mechanisms and transmission protocols, including data encryption and identity authentication, to ensure secure data transmission and protect against leaks or cyberattacks.

Remote Maintenance with Program Upload/Download – In conjunction with the remote maintenance tunnel, the gateways enable remote PLC programming, debugging, and program upload/download from anywhere—reducing travel costs, improving maintenance efficiency, and lowering operational expenses.
