Sampling Intervals

250ms-5sec based on tag criticality. Critical alarms at 250ms, normal process at 1-5sec.

Deadband Filtering

Report only when value changes >1% of scale. Reduces notification traffic by 50-70%.

Auto-Reconnect

Exponential backoff on network interruption. Session restoration with full subscription recovery.

Modbus TCP Poll Scheduler

Priority	Poll Interval	Use Case	Examples
Critical	1 second	Alarms, safety, faults	VFD fault code, safety relay status
Normal	5-15 seconds	Process variables	Motor current, pump speed, tank level
Slow	30-60 seconds	Diagnostics, counters	Runtime hours, energy consumption

BACnet/IP Client Manager Building Automation

Object Reading

Read Analog Input/Output, Binary Input/Output, Multi-state Values. ReadProperty and ReadPropertyMultiple support.

COV Subscriptions

Subscribe to Change-of-Value notifications. Reduces network traffic vs. polling. Configurable lifetime renewal.

Write-Back

WriteProperty commands for setpoints, schedules, overrides. RBAC-controlled with audit logging.

                📡 BACnet Integration Examples
                Niagara JACE: Read zone temps (AI), damper positions (AO), occupancy sensors (BI), HVAC modes (MV)
WEBs Controllers: Monitor VAV airflow, discharge temps, CO2 levels across 50-200 zones
AHU Controllers: Track supply/return air temps, fan speeds, filter status, energy meters
Write-Back Use Cases: Adjust setpoints based on occupancy, override schedules, trigger alarms

            

Adaptive Polling Algorithm

                🧠 Pattern Learning

Classification: Static (StdDev <1%) vs Dynamic (StdDev >1%)
Frequency Adjustment: Reduce static tag polling by 50-75%
Change Detection: Resume fast polling when value changes >2%
Result: 30-50% reduction in network traffic on stable processes

            

Connection Health Monitoring

TCP Keepalive

60-second ping to all data sources. 3 missed probes → mark offline (180 sec detection).

Retry Logic

Exponential backoff: 5s → 10s → 20s → 40s → max 5 min. Retry indefinitely until restored.
