Function & Feature Highlights

1. Dedicated P-NET Fieldbus Matching Design: Optimized built-in P-NET protocol communication stack, realize seamless data interconnection with all MAS series P-NET bus control modules and field monitoring equipment, become standard local operation terminal of P-NET industrial monitoring system
2. High-Resolution 256×64 Graphic LCD Display: Monochrome graphic dot matrix screen supports multi-line real-time industrial parameter simultaneous display, text alarm prompt, numerical curve trend simple drawing, clearly present complex process control system operating state data
3. Full-Function 42-Key Membrane Matrix Keyboard: Complete numeric input, menu navigation, parameter modification, equipment control shortcut keys integrated on front panel membrane key layer, on-site operators can complete all system operation work without external mouse or touch input device
4. Multi-Protocol Serial Communication Compatibility: Besides native P-NET bus support, built-in Modbus RTU and ASCII protocol conversion function, can be connected with third-party brand PLC, power monitoring instruments and sensor signal acquisition modules through RS485 bus to expand system compatibility
5. Built-In System Parameter Storage Memory: Non-volatile Flash memory chip stores user-modified operating parameters, alarm threshold values and communication protocol configuration parameters; stored data will not be lost after terminal power-off completely
6. Front Panel IP40 Dust-Proof Integrated Structure: Integrated one-piece front panel with membrane key layer and LCD screen embedded, sealed dust-proof edge rubber strip between front panel and cabinet mounting cutout, effectively prevent cabinet internal metal dust and debris entering terminal internal circuit components
7. Real-Time Fault Alarm Information Storage & Query: Automatically record all equipment fault alarm events with timestamp, store up to 200 historical fault records inside Flash memory; operators can enter dedicated fault log menu through membrane keys to view historical fault data for post-failure equipment maintenance analysis
