Summary
This driver provides extensive process monitoring capabilities for flow systems, including:
- Real-time flow, pressure, temperature, and energy measurements
- Calculated properties like density, viscosity, compressibility
-
Statistical tracking (min/max/average)
- Totalization and event timing
- System diagnostics via fault flags and timestamps
👉 Practical takeaway:
- This is a high-data-density process driver
- Best used in flow / energy monitoring applications
- Requires careful tag setup (especially for string and real values)
- Limited write capability — mostly monitoring-focused with selective control/reset functions
