Automatic controller identification and parameter display: The unit automatically identifies the connected controller and shows its type, model and relevant parameter data, helping reduce setup time and minimize configuration errors. Largescreen multifunction LCD: A wide display presents all operational data and system status in digital, graphic and textual formats for quick, ataglance monitoring. Six navigation function keys: Direct, convenient, and rapid operation with dedicated keys that streamline common tasks and navigation. Realtime energy statistics recording: Continuously captures energy usage data for monitoring, analysis and optimization. Use scenarios Industrial control panel or cabinet: When installing or maintaining automation equipment, the system automatically detects the controller, presents its model and parameters, and allows technicians to navigate settings quickly with the six keys, reducing downtime and ensuring accurate configuration. Facility or datacenter energy management: Use the device to monitor realtime energy consumption of connected controllers and systems, with the large LCD providing a clear overview and the energy statistics feature supporting analysis and efficiency improvements. Laboratory test bench or RD setup: Researchers can monitor system status, controller parameters and operational data in multiple formats on a single display, while using the navigation keys to perform quick checks and adjustments during experiments.
