Mitsubishi Electric has expanded its GOT2000 series of Human-Machine Interfaces (HMI) with two new widescreen versions. The ability to display additional information gives users of the new GT21 and GT25 widescreen HMIs the opportunity to improve machine operability and the potential to increase productivity. Other valuable features include the VCN server, two separate Ethernet ports and a built-in sound output interface that can be used for spoken warnings or information.
The GT21 is a 7" widescreen Graphical Operator Terminal (GOT) with WVGA resolution and on-board Ethernet, CC-Link IE Field Basic, RS-232 and RS-422/485 connectivity. The GT25 is available in both 7" WVGA and 10" WXGA and adds a second Ethernet port for greater flexibility, as well as support for wireless LAN connectivity.
The GT25 model's second Ethernet port allows users to physically separate the connections to the information system and control system networks. The ability to set different IP addresses for each network helps to increase security.
The GT25 also offers an audio output interface, with built-in speaker and amplifier. This allows the HMI to not only emit an audible alarm or warning signal, but also play back spoken warning messages or operator instructions. In addition to the information displayed on the screen, spoken operator instructions can be an important tool in increasing productivity.
Remote monitoring and additional features
Along with all the standard features of the existing GT21 and GT25 series, the new GOT2000 widescreen HMIs offer remote monitoring capabilities with the VNC server function. By connecting to the GOT remotely from a PC or tablet, users can monitor and control production and connect to system devices. Additional features on both new GOT models include GOT Drive, which allows servo system start-up, setup and maintenance to be performed directly via the GOT. Stylish and compact, with a narrow bezel, both GOT models are also future-proof in terms of design.
