Low cost graphic operator interfaces

December 2011 Operator Interfaces, Switches & Relays

Pro-face has introduced low cost HMI Ethernet graphic operator interfaces to its GP4100 series. The new models feature full graphic and touch operation capability and are equipped with 85 mm, 16-greyscale and high-resolution 200x80 pixel displays and USB interfaces.

The series offer high quality screens with expanded support of Windows images and Bitmap fonts can be made even on a small HMI display. Two types of three-colour LED backlights, green, orange and red or white, pink and red can provide operators with easy to see operational status.

There are three types of communication models, RS232C, RS422 and RS485, with selectable isolation for the choice of controller and application requirements. Useful new functions such as scrolling display of alarm messages, history logging of alarms, recipe functions and clock synchronisation with controller data, support the HMI.

Two USB interfaces, Type A and mini-B are standard, as well as support for data transfer from a PC via the mini-B port. Support for a USB memory data transfer via the Type A interface does not require a setup engineer to take a PC to the factory floor to update its programs. The Type A interface can be used to connect various devices, such as a USB code reader and serial communication device via a USB-SIO conversion cable.

GP4100 Series is supported by new GP-Pro EX Ver. 2.6 editor software. A limited edition of the software can be tested using the free download service from the Pro-face web site.
