Supply Chain Resilience
Mapping tier-2 and tier-3 supplier dependencies for risk mitigation. Stop relying on vendor promises and implement tested shop-floor architectures.
Phase 1: Environment Audit
Before any hardware or software is purchased, a strict environmental audit is required. Legacy systems (pre-2010 PLCs) often lack the CPU cycles to handle encrypted MQTT payloads.
Audit Checklist
- Network Topology (Purdue Model adherence)
- Existing SCADA polling rates
- Physical environment constraints (Thermal/Vibration)
Phase 2: Data Modeling
Ensure that all data points are contextualized. A boolean value of true means nothing if the historian doesn't record which machine state triggered it. Adopting a Unified Namespace (UNS) is non-negotiable for scale.
Common Protocol Implementations
| Layer | Recommended Standard | Avoid |
|---|---|---|
| Edge Telemetry | MQTT Sparkplug B | Custom REST APIs |
| Machine Control | OPC UA | Proprietary serial |
| Historian | Time-Series DB (e.g. Influx) | Relational SQL |
FAQ
- Can we skip the edge layer and go direct to cloud?
- Only if your process can tolerate >200ms latency. For high-speed sortation or CNC monitoring, an edge layer is mandatory to prevent buffer overflows.
