Register Discovery

Modbus TCP Polling Grid

Select a device profile to inspect its independent FC03 holding-register grid. Changed rows receive a brief soft glow. Checked rows are monitored priority variables.

NORMAL

Incinerator CEMS is operating normally. All emissions (SO2, NOx, CO) are well below their respective limits for the past hour. Data quality is high with fresh samples and analyzer OK.

Highest utilization: NOx · 53.3%

Confidence: high
