MITSUBISHI ELECTRIC GT25 Human Computer Interface Application Guide

Check communication parameters (baud rate, data bits, station number) and test the loop for cable breakage and protocol setting errors during communication timeout with PLC.

Slow screen switching, approaching full memory or complex scripts, reducing the number of objects per page, optimizing script loops.

5.3 System Starter Advanced Applications

Module fault diagnosis: When the PLC reports "SP.UNIT ERROR", check the detailed error of the specific intelligent module through the system starter (such as AD module disconnection).

Backup and recovery: Directly backup PLC programs through USB flash drive (with PLC support), without the need for a PC.

Ladder diagram monitoring: In conjunction with GOT's "Ladder Monitor" function (requiring additional authorization), PLC ladder diagrams can be monitored online on HMI, greatly improving on-site troubleshooting efficiency.

5.4 Remote Maintenance Plan

By using GOT Mobile and VPN routers, engineers can connect to the factory HMI at home, view alarm records, and upload new screens.

For multiple sites, Mitsubishi's "GOT Remote Service" cloud platform (GT27 or specific version required) can be used to achieve secure remote penetration.

Typical Industry Application Cases

6.1 Packaging Machinery (Pillow Packaging Machine)

Requirements: Multi temperature zone control, servo cutting, production counting, formula management.

Configuration: GT25 (8.4 inches)+FX5U PLC+MR-JE servo.

Highlight: Use formula function to store set values for different packaging specifications; Debugging servo trimming curve through GOT Drive; The MES interface uploads the production output to the workshop database.

6.2 Peripheral equipment of injection molding machine (robotic arm, mold temperature machine)

Requirement: Real time display of robotic arm position and alarm information, supporting remote diagnosis.

Configuration: GT25 (12.1 inches)+Q series PLC+Ethernet.

Highlight: The system starter quickly locates PLC communication faults; GOT Mobile allows supervisors to view the operational efficiency of robotic arms in the office.

6.3 Small scale water treatment control system

Requirement: Monitor pumps, valves, liquid levels, and flow rates, and store data in SQL Server.

Configuration: GT25+FX3U PLC+serial port instrument.

Highlight: GT25 can simultaneously read PLC and serial instrument data, and directly write them into the database through MES interface without the need for an upper computer.

Selection suggestions and accessory selection

Display size: When displaying complex trend charts or large amounts of data, select 12.1 inches (VGA 640 × 480); When high-resolution display of fine graphics is required, choose 8.4-inch SVGA (800 × 600).

Storage Expansion: Standard projects typically have less than 20MB, with 80MB of RAM sufficient; If you need to record data logs (CSV) for a long time, it is recommended to use a USB flash drive.

Wireless requirements: Choose the GT25 WLAN model or order a wireless communication unit (GT25 WiFi).

Environmental adaptability: For high temperature or strong vibration environments, the GT25 oil proof type or equipped with a cooling fan can be selected.

Accessories

USB protective cover (prevents dust from entering)

Installation bracket and sealing gasket (required for IP67F)

Connecting cable (GT25-C * * * series)

Future Upgrades and Compatibility

GT25 is fully compatible with GOT2000 series engineering files and extension modules. When upgrading from old GOT1000 models (such as GT16, GT15), the engineering conversion tool of GT Works3 can be used, but it should be noted that some objects (such as old alarm lists) may need to be manually adjusted. For applications planning to use new generation networks such as CC Link IE TSN, it is recommended to choose the GT27 series.
