Programmable Logic Controllers (PLCs) are one of the core devices in industrial automation and are the key application that enables factories to operate in an automated manner. A PLC typically consists of multiple internal modules specifically designed for operations such as logic control, sequence control, timing control, and counting control. For example, through IO interfaces, sensors are connected to monitor various variable signals, and output commands can be issued according to the program to drive the operation of various actuators.

In addition, PLCs can exchange data with other devices through various communication protocols, enabling remote monitoring and control, and can detect and alert system faults. In this regard, data acquisition gateways connected to a wide range of PLCs enable protocol parsing and data acquisition for Siemens, Mitsubishi, Omron, Schneider, Delta, Inovance, and other PLCs, providing a comprehensive and reliable data source for the data management platform and ensuring the efficient and safe execution of related work. 1. Equipment Monitoring and Online Management
By connecting to controller PLCs, the gateway can collect equipment operating status and process parameters in real time and connect them to workshop data dashboards or MES systems, thereby providing insight into equipment OEE and status parameters and enabling rational arrangement of production tasks.

2. Output Counting and Quality Monitoring
By installing additional sensors and collecting internal counting data from the PLC, data such as equipment output and quality can be collected and summarized into data reports, thereby providing insight into daily, monthly, and annual output, single-day production efficiency, product pass rate, and other information.

3. Fault Alarms and Remote Maintenance
Alarm thresholds can be set to enable automatic alarms via WeChat, SMS, email, and other methods, and operations such as remote programming and debugging and remote program upload/download for PLCs can be performed, effectively improving work efficiency and management levels.
