Unitronics Vision280 Overview

Vision280™ : PLC with Touchscreen Graphic HMI & Snap-in I/O Modules

The Vision280™ is a powerful PLC with a built-in HMI Operator Panel, comprising a 4.7” graphic touchscreen display and a customizable keyboard. On-board I/Os can be added by simply snapping a module onto the back of the PLC; Snap-in I/O Modules come in several configurations. I/O Expansion modules enable integrating up to 171 I/Os per Vision PLC.

The Vision280™offers a rich range of embedded features such as multiple auto-tuned PID loops, internal 120K structured database and loadcell support. Communication options include TCP/IP, Ethernet, GSM/SMS, MODBUS, CANbus networking, function blocks that enable Vision to communicate with devices using proprietary COM protocols, plus remote access and data export software utilities.

1000K-Ladder code application memory enables the Vision280™ to run complex control and automation tasks.
The touchscreen HMI enables the display of ‘touchable’ images and text according to real-time conditions—for on-line operation and diagnostics. It can also display graphs according to historical values—to reflect trends of recorded data. Display options are almost endless with up to 255 user-designed screens, and up to 24 HMI variables per screen.

The Vision PLC/Graphic HMI series introduces an unbeatable price-performance ratio, enabling users to enjoy the advanced features of both the operator panel and the PLC, while maintaining low budget, reduced programming time and minimum wiring.
