What Is SCADA? Supervisory Control Without Replacing the PLC
SCADA sits above PLCs and RTUs: it acquires field data, alarms operators, and issues supervisory commands across plants and remote assets—without replacing local deterministic control.



The PP845A 3BSE042235R2 is a space-saving human-machine interface device configured to deliver real-time process monitoring and machine-level control across industrial automation systems. Operating as a high-performance Panel 800 Operator HMI, this terminal features an integrated color liquid crystal touch display designed for displaying graphical objects, structural plant text, and dynamic system variables. The underlying hardware platform utilizes updated processor and power electronics to interpret operator inputs and manage fieldbus interactions. Engineered specifically for seamless operation inside the ABB Control Network and alongside AC 800M controllers, the PP845A 3BSE042235R2 supports integrated controller-level alarm handling and remains compatible with multiple third-party PLCs through an embedded driver library.
