Field instruments, PLCs, communication networks, and the HMI each play a distinct role.
PLC vs. RTU: When Each Is Used
Both execute local control logic, but they've historically served different roles in the water/wastewater industry.
Historian Data & Trending
A SCADA historian stores time-series data long-term, the foundation for trend-based troubleshooting.
Redundancy in SCADA Architecture
Redundant servers, networks, and power supplies keep monitoring and control available during a single-point failure.
