The HMI can access PLC variables directly, avoiding the cumbersome tables of variables that are often needed when separate devices are used.
Moeller Electric's easyHMI MFD4 is a 5.7in multifunction display unit with built-in PLC functionality and support for the easySoft-CoDeSys programming system.
Combining the HMI and PLC functions in a single unit saves money and space and simplifies programming, as the HMI can access PLC variables directly, avoiding the cumbersome tables of variables that are often needed when separate devices are used.
Designed for use in demanding of industrial applications, the MFD4 has a full-colour touch screen that is protected to IP65.
The 320 x 240 pixel resolution of the screen facilitates the display of high-quality graphics and text.
Straightforward integration with almost any type of automation system is assured by Ethernet, CANopen and RS232 connectivity.
The Ethernet interface allows FTP access to the MFD4 file system, offering a convenient on-line method of exchanging recipes, status information and similar data with the unit.
In addition, the Ethernet connectivity gives access to the unit's integral web server, allowing its screen display to be mirrored at remote locations using any standard internet browser.
The CANopen interface allows motor starters to be controlled directly via the Moeller Electric SmartWire panel wiring system.
In addition, CANopen permits straightforward and cost-effective connections to remote I/O modules and variable speed drives.
Based on Windows CE, the MFD4 multifunction display unit from Moeller Electric has 64Mbyte of onboard SRAM, 2Mbyte of Flash for data and program memory, 6Mbyte of display memory and an integrated real-time clock.
Standard Multimedia memory cards are also supported and can be used as a convenient way of transferring or archiving programs and data.
