Intuitive Pump Station Monitoring with a P&ID Process Diagram
A P&ID mimic shows the clean-water tank level filling and the pump impeller turning; with no separate SCADA server, a single HMI reads the PLC directly to visualize the site.
How this HMI works
It displays water level, flow rate, discharge pressure, and totalized flow in real time, and also monitors dual-pump alternating operation along with water quality and temperature. It connects directly to domestic PLCs such as the LS XGB over Modbus and LS XGT, so no SCADA server is required.
Key features
Animated P&ID mimic
Renders tank level, impeller rotation, pipe flow, and valve status graphically.
Multiple trends · totalization
Aggregates trend graphs for level, flow, and pressure along with totalized flow.
Dual-pump alternation
Displays P1/P2 alternating operation and automatic control status.
Intelligent alarms
Automatically detects overpressure, overtemperature, dry running, and communication loss, and keeps a history.
Water quality · temperature monitoring
Monitors water-quality items such as residual chlorine, turbidity, and pH.
No SCADA required
The HMI polls the PLC directly, reducing server build-out cost.

How it connects to equipment
Every EGNOX custom HMI commonly supports Wi-Fi and Ethernet networking, OTA over-the-air firmware updates (signature verification · rollback), remote screen viewing in a web browser, and multilingual operation (Korean/English). The communication register map is mapped to your equipment model during the screen design stage.
