The rise of robotics and the core support of industrial automation - how PLC/DCS modules enable intelligent manufacturing

February 08, 2025

As the global manufacturing industry accelerates its transformation towards intelligence and flexibility, industrial robots have become the core productivity of modern factories. From the robot dance performance at the 2025 Spring Festival Gala to the welding robot arm in the automobile factory, from the AGV cart in logistics warehousing to the collaborative robot in the medical field, the widespread application of robotics is inseparable from the support of the underlying control technology of industrial automation. As a core component supplier in the field of industrial automation, SWAN ELECTRIC CO., Ltd (official website: www.abplccenter.com) provides key technical support for the precise control, efficient coordination and stable operation of the robot system through high-performance PLC (programmable logic controller) and DCS (distributed control system) modules. ※PLC/DCS: The "brain" and "nervous system" of the robot system Robots are not isolated devices. Their action execution, signal processing and environmental perception all rely on industrial automation control systems. PLC: The core of precise control of robot movements Application scenarios: In automobile manufacturing, welding robots need to complete complex trajectory movements with millimeter-level accuracy; in the electronics industry, assembly robots need to quickly respond to sensor signals and adjust action parameters. Product support: AB ControlLogix series and CompactLogix series PLC can drive multiple servo motors at the same time with high-speed computing capabilities (supporting nanosecond instruction cycles) and multi-axis linkage control functions to ensure the accuracy and real-time performance of robot joint movements. In addition, its modular design supports flexible expansion of I/O interfaces and adapts to sensors and actuators of robots of different brands. DCS: "Command Center" for Multi-Robot Collaboration Application scenarios: In smart factories, dozens of robots need to collaborate to complete material handling, processing and inspection tasks, and the system needs to monitor the global status in real time and dynamically adjust task allocation. Product support: ABB DCS-AC500 series distributed control systems achieve multi-node communication through high-speed industrial Ethernet (supporting Profinet and EtherCAT protocols), and can centrally manage the operating data of hundreds of devices. For example, in the Spring Festival Gala robot performance, the DCS system can coordinate the synchronous actions of multiple robots to avoid queue dislocation caused by signal delay, which is a typical application extension of your company's DCS module in the field of stage automation. ※The technical advantages of our products and the adaptability of robot scenes High reliability and anti-interference ability Electromagnetic interference, vibration and temperature and humidity changes in industrial environments may affect the stability of robots.
