NHP has introduced three new high function touch screen terminals to the ESA product line, the VT575, VT585 and VT595. These products feature 7.5", 10.4" and 12.1" displays at a resolution of 640x480 up to 800x600.

With a large project memory capacity of 7MB, users have considerable space for applications and graphic images. Recipe data is stored in flash memory thus ensuring valuable process data is not lost due to faulty or discharged batteries. Multiple processors, one for the display and one for communications, allow high-speed operation. Sophisticated graphic objects like potentiometers, sliders and dials are available.

The terminals contain two serial ports allowing simultaneous communication to different front-end devices. In this mode of operation, the panel may be configured to communicate with dual PLCs of the same brand or as a gateway between different PLC brands or devices. The option of integrated 10/100 Ethernet offers connectivity to the latest industrial devices and corporate LANs. Profibus DP and CANOpen fieldbus networks are also supported.

Programming the new panels is achieved with the latest version of VTWIN. The Windows based software is intuitive, easy to use and includes a graphics editor for developing professional looking screens with a minimum of fuss. VTWIN is used to program the entire range of ESA terminals from the low-end text based panels to the high-end graphics based touch panels.
