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.

Designed for mobile operation and direct machine-side control, the GT1155HS-QSBD serves as a rugged, handheld human-machine interface (HMI) within the Mitsubishi Electric GOT1000 platform. This "Handy" series operator terminal integrates physical tactile controls and high-reliability safety features directly into the portable housing, making it optimal for manual machine setups, teaching operations, and local debugging tasks.
The unit features a bright 5.7-inch STN color display with a QVGA resolution of 320 x 240 pixels. To ensure safe operation in manual mode, the device incorporates physical operator controls, including six application switches, a key-operated selector switch, and a three-position grip switch (enabling/deadman switch). Equipped with multi-channel serial connectivity and storage expandability via CompactFlash, this terminal interfaces seamlessly with MELSEC PLCs and other industrial controllers.
