Feature rich mid-range HMI
14 August 2012
The GT14, a new 5.7in HMI from Mitsubishi, is available in both monochrome and colour versions providing a screen resolution of 320x240 pixels and including a variety of features designed to offer increased flexibility and capability to control systems.
The colour version includes a TFT screen displaying 65,536 colours for enhanced clarity instead of the 256 colours more typical at this price-point. The monochrome version employs an STN screen offering 16 grey scales. Both products include features such as long-life LED backlighting, analogue touch functions, front-face USB port, an SD card slot, IP67f front panel sealing, and the option of Ethernet communications.
A key feature of the GT14 is said to be its communications options. RS232 and RS422/485 ports are included as standard, with Ethernet available as an option. The HMI also includes an ‘FA Transparent’ function that enables a connected PC to link directly through to Mitsubishi Electric FA products such as PLCs, inverters and servo drives.
USB ports enable simple transfer of operating system and project data, as well as allowing the connection of a keyboard and mouse. In addition to the traditional USB port on the rear of the terminal, the GT14 also features a USB port on the front face, making it easier to transfer data to and from the terminal without having to open up the panel. The front port is protected by a cover which maintains the IP67f protection. An SD card slot completes the communications possibilities, enabling standard SD cards to be used for logging and backup/restore functions for PLC programs and parameters.
The HMI allows for data logging from remotely connected devices such as PLCs and temperature controllers, with the built-in RAM able to store up to 2,000 data points. Data can then be stored or transferred on SD card or USB memory devices
