Integrated PLC and HMI

Unitronics’ Vision350 incorporates all colour advantages into a compact all-in-one PLC/HMI device. Colour displays are becoming common in today’s automation. They enable machine builders to show more details on the operator panels and to display vivid, attention-grabbing alarms.

This PLC and enhanced HMI is equipped with a 3.5" colour touch screen, an improved processor and diverse I/O options. Adaptable to most TCP/IP/serial protocols, the Vision350 offers ethernet connection via TCP/IP, GSM/SMS/GPRS, Modbus, CANopen and UniCAN, and also includes remote access utilities.

The Vision350’s HMI is capable of supporting 3 MB of application memory for images and 512 KB 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 complex recipe programs. At 24 PID loops with auto-tune, plus onboard thermocouple and PT100 inputs, the Vision350 incorporates a full-function temperature controller.
