Introduction
A mid-sized automotive parts manufacturer struggled with frequent production line stoppages. Their legacy HMIs, over a decade old, caused slow response times and data loss. The plant needed a modern, reliable operator interface to restore uptime and improve data visibility. The Mitsubishi GT1455-QTBDE from the GOT1000 series emerged as the ideal solution, offering a compact 5.7-inch touchscreen with robust connectivity.
Customer Challenge
The customer operated three assembly lines for engine components. Each line relied on outdated monochrome HMIs that often froze during high-speed production. This led to an average of 45 minutes of unplanned downtime per shift, costing the plant over $120,000 annually in lost output. Additionally, the old units lacked Ethernet, forcing operators to manually record production data, which introduced errors and delayed decision-making. The maintenance team spent hours troubleshooting intermittent communication failures, further straining resources.
The Solution
SpareTechPLC recommended replacing all three HMIs with the Mitsubishi GT1455-QTBDE. This 5.7-inch diagonal TFT color display supports 65,536 colors, providing clear visualization of complex machine states. Its built-in Ethernet interface enabled seamless integration with the plant's existing PLC network, allowing real-time data logging and remote monitoring. The unit consumes only 8.40W (350mA at 24VDC) during normal operation, reducing energy costs compared to the older models. Installation took two days per line, with minimal disruption to production schedules.
Results and Benefits
After deployment, the plant reported a 30% reduction in unplanned downtime, saving approximately $36,000 per quarter. The GT1455-QTBDE's permissible instantaneous power failure time of within 5ms prevented data loss during brief voltage dips, a common issue in the facility. Operators now access production metrics instantly via the Ethernet connection, improving shift handovers and quality control. The maintenance team also benefits from the unit's noise immunity of 1000Vp-p, which eliminated false alarms caused by electrical interference.
Key Takeaways
This case demonstrates that upgrading to a modern HMI like the GT1455-QTBDE can deliver rapid ROI through reduced downtime and better data access. For plants with aging operator interfaces, the GOT1000 series offers a cost-effective path to Industry 4.0 readiness.
