February 12, 2009 — Unitronics' updated Vision350 incorporates all-color advantages into a compact all-in-one PLC/HMI device. Color displays are becoming common in today's automation. They enable machine builders to show more details on the operator panels, to display vivid, attention-grabbing alarms, and, in general, to brighten up their systems. This power PLC and enhanced HMI is equipped with a color touchscreen, 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 & UniCAN, and also includes free remote access utilities.On the surface, the Vision350’s fully functioning HMI features a 3.5" color touchscreen display, capable of supporting 3MB of application memory for images, and 512K for fonts, allowing about 250 images and 1024 displays per application. Five programmable keys allow customization of function and layout (e.g. keys could be labeled 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 15µsec per 1K 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. Internal 120KB database enables datalogging 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. This new and improved combination of features enables engineers and systems designers to benefit from a powerful upgraded PLC and color touchscreen HMI within a bare minimum of budget, cabinet space, and wiring. About Vision Series OPLCs and VisiLogic SoftwareA Vision Series controller is a compact PLC with snap-in I/Os and a Graphic/Touch/Color Operator Interface. Vision’s integral HMI panel contains a graphics-ready LCD, function keyboard and/or touchscreen. This enables you to use graphic images and bar graphs to represent real-time variable data, create and show text instructions, and to display actual run-time system data. The operator uses the keyboard to enter or modify system data. Vision’s snap-in I/Os offer D/A inputs including HSC/shaft-encoders/frequency measurers, and relay/transistor outputs including PWM. Some models also offer direct temperature measurement, for the process industry. Communication options include TCP/IP Ethernet, GPRS/GSM and SMS, Web Server and E-mails, MODBUS and CANbus.
