In the wave of industrial digitalization, 80% of manufacturing enterprises face the pain point of 'blind spots' in device data. As the core of industrial automation, PLC devices, how to make its massive data truly 'live' will directly determine the level of factory digitalization.
Lubangtong, with 15 years of deep cultivation in the field of device IoT, unveils the implementation path and value code of PLC device data acquisition for you.
Why is PLC Data Acquisition Considered the Cornerstone of Smart Factories?
PLCs, acting as the 'central nervous system' of industrial equipment, generate tens of thousands of operating parameters daily. However, in traditional factories, this data often lies dormant in local controllers, making it difficult to trace equipment operating status, relying on experience for fault response, and depending on intuition for energy consumption management.
Real-time networking of PLC data through data acquisition technology enables enterprises to build digital equipment platforms, achieving a transformation and upgrade from 'experience-driven' to 'data-driven.
Four Steps to Establish a Complete PLC Device Data Collection Link
1. Smart Gateway Establishes a "Data Bridge"
Robustel industrial gateways are designed to establish a seamless "data bridge" for industrial applications.
These gateways offer rapid device connection, typically within 5 minutes, through Ethernet and serial ports, and support a wide array of mainstream PLC protocols, including Siemens, Mitsubishi, and Omron. This broad compatibility extends to various industrial equipment such as PLC, CNC machines, and robots from numerous leading brands.
Furthermore, Robustel gateways are engineered to adapt to diverse device communication interfaces, ensuring flexibility in deployment across different industrial environments. They also support mainstream industrial protocols like Modbus, OPC UA, and S7.
2. Edge Computing Creates the "Most Powerful Brain"
Edge computing gateways, deployed at the device level, provide a unified management solution for diverse industrial equipment. This deployment facilitates real-time, millisecond-level analysis and early warning for critical device parameters.
Specifically, these gateways enable millisecond-level real-time data cleaning and standardization of data formats, ensuring data consistency and accuracy. They also perform critical parameter threshold judgment and multi-dimensional parameter anomaly analysis, allowing for proactive maintenance and operational optimization.
Moreover, data compression capabilities are integrated to reduce transmission bandwidth occupation, optimizing data transfer efficiency.
3. Secure Transmission Builds the "Data Artery"
To ensure secure data transmission from the workshop to the management platform, the system utilizes VPN and TLS dual encryption channels, providing comprehensive data protection. This end-to-end encryption safeguards data integrity throughout the transmission process.
Additionally, breakpoint resumption capabilities are implemented to maintain data integrity and reliability, ensuring that data transfer can be resumed without loss in case of interruptions.
Furthermore, multi-network redundancy, utilizing a hybrid of 4G/5G, wired, and WiFi connections, is employed to enhance network reliability and ensure continuous data flow.
4. Visualization Platform Achieves "Unified Screen Management"
Connecting to the Robustel device management platform enables real-time visualization of crucial operational data, including device utilization, energy consumption curves, alarm statistics, and work order services.
This platform facilitates comprehensive device digital management, providing a centralized hub for monitoring and control. Furthermore, it features a visualized data analysis dashboard, presenting insights through intuitive graphical representations for enhanced understanding and decision-making.
To integrate seamlessly with existing systems, the platform offers API interface connections to MES and ERP systems, streamlining data exchange and workflow automation.
