Touch-screen PLC

Micromax Sensors and Automation has announced Unitronics’ Vision350, which incorporates all colour advantages into a compact all-in-one PLC/HMI device.

This power PLC and enhanced HMI is equipped with a colour touch screen, an improved processor and diverse I/O options.

Adaptable to most TCP/IP/serial protocols, it offers communication features, such as ethernet connection via TCP/IP, GSM/SMS/GPRS, Modbus, CANopen and UniCAN and also includes free remote access utilities.

On the surface, the device’s fully functioning HMI features a 3.5" colour touch-screen display, capable of supporting 3 MB of application memory for images and 512 K for fonts, allowing about 250 images and 1024 displays per application.

Five programmable keys allow customisation of function and layout (eg, keys could be labelled as arrow keys using a supplied keypad slide). Enhanced programming features include trending, built-in alarm screens and easy HMI language support.

This high-speed PLC allows for 1 MB of logic memory and a scan time of 15 µs per 1 K of typical application. It also offers up to 38 onboard digital and analog I/Os that can expand up to 166 and includes digital and analog I/Os, temperature measurement and load cell inputs.

An internal 120 KB database enables data logging and supports complete recipe programs.
