Case example (conceptual) An industrial site uses Modbus TCP to monitor 1,000 registers across many devices. Traditional cyclic polling every second overwhelms the network and yields stale data for critical variables. Introducing a “poll key” layer: each register is tagged with a policy (critical: 1 s, normal: 10 s, event-driven: subscribe). An edge gateway performs fast scans of physical devices at a conservative rate, caches values, and pushes updates for event-driven tags over MQTT to the SCADA master. The master polls the gateway cache per-policy instead of polling each device directly. Result: network load drops, critical data latency improves, and the system scales without replacing field devices. License Type Price (USD) Single-User Multi-User $119
