Automatically identifies the connected controller and displays its type, model and relevant parameter data, reducing setup time and ensuring accurate configuration. Largescreen multifunction LCD displays all operational data and system working status in digital, graphic and textual formats for clear monitoring and quick interpretation. Six navigation function keys provide direct, convenient and rapid operation for common tasks. Realtime energy statistics are recorded for ongoing analysis and performance tracking. Use scenarios Factory automation: technicians can quickly identify the active controller, verify type and model, and review parameter data during commissioning or troubleshooting, while observed system status is readily visible on the large screen. Building energy management: realtime energy statistics are captured for monitoring usage, informing efficiency improvements and generating reports. Maintenance and development labs: engineers navigate functions with six keys and view data in multiple formats to test, compare, and validate controller configurations efficiently.
