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.

Integrating critical machine visualization and control functionalities into automated environments, the GT2105-QMBDS serves as a reliable operator terminal within the Mitsubishi Electric GOT2000 Series. This compact human-machine interface (HMI) features a 5.7-inch monochrome TFT display designed to optimize operational visibility while minimizing panel space footprint. It acts as a primary interface point for monitoring real-time system parameters, diagnostic alarms, and process status directly on the factory floor.
Engineered for seamless industrial communications, the unit supports connection to automated PLCs, variable frequency drives, and other smart devices via built-in serial and Ethernet ports. The integrated SD memory card slot and USB interface allow for convenient project maintenance, system OS updates, and CSV logging without requiring dedicated programming hardware at the machine site.
