Mitsubishi GOT2000 HMI: How to Choose GT21, GT23, GT25 or GT27
By AB Automation Team3 min read
The human-machine interface (HMI) is the part of your machine operators touch every day. A well-designed HMI cuts setup time, reduces mistakes and makes troubleshooting faster. Mitsubishi Electric's GOT2000 HMI series is designed to work seamlessly with MELSEC PLCs, MELSERVO servos and FR-series drives, and it is configured with GT Designer3 software.
The GOT2000 models at a glance
| Model | Class | Typical use |
|---|---|---|
| GT21 | Compact, basic | Small machines and stand-alone equipment needing a simple, low-cost operator panel. |
| GT23 | Standard | General machines needing reliable touch control at an economical price. |
| GT25 | Advanced | Most production machines: more interfaces, more memory and wider screen sizes. |
| GT27 | High-end | Multi-touch gestures, high-resolution screens, video and advanced data functions. |
There are also handheld GOT models for teaching and setup, and the GOC series that combines an HMI and a controller in one unit, which we use in our boiler energy-saving system.
Features that save engineering and maintenance time
- FA transparent function: connect your laptop to the GOT and program or monitor the PLC, servo or drive through it, without opening the panel.
- Sequence program monitor: view the PLC ladder on the HMI itself, so maintenance staff can trace why an output is not turning on.
- Alarm history and logging: store alarms and process data with time stamps for root-cause analysis.
- Recipe functions: store product settings for quick changeovers on packaging and textile machines.
- Remote access: with the right options, view and operate screens from a PC or mobile for support.
- Multi-language screens: switch between English, Hindi, Gujarati and other languages for different operators.
How to choose the right model
- Screen size: count how much information must be visible at once. Small machines may manage with 4.3″ or 5.7″; complex lines usually need 8.4″ to 15″.
- Connections: list every device the HMI must talk to (PLC, drives, barcode reader, printer, SCADA). Higher models have more ports and options.
- Data needs: logging, recipes and reports need memory and an SD card; check before you choose an entry model.
- Environment: washdown, dust or direct sunlight affect front-panel rating and brightness requirements.
HMI screen design tips
- Keep a consistent layout: navigation in the same place on every screen, alarms always one touch away.
- Use colour for meaning only (red = fault, green = running, yellow = warning) and keep backgrounds neutral.
- Write alarm messages that say what to do, for example "Guard door 2 open: close door and press Reset", not just "Alarm 12".
- Protect setup and parameter screens with password levels for operator, supervisor and engineer.
- Show the machine state clearly: auto, manual, stopped, faulted.
Replacing an old GOT1000 or third-party HMI
GOT2000 can convert many GOT1000 projects with GT Designer3, and mounting dimensions are often compatible. When replacing another brand, we redraw the screens and usually improve them at the same time, adding alarm help text and diagnostics that the original lacked.
