Unitronics' Vision430 device features a 4.3" built-in color touchscreen that brings added value to any application that requires a compact PLC controller with onboard I/Os. The touchscreen and five function keys are housed in a flat fascia with an IP66/IP65/NEMA4X rating-a fine fit for the food and pharmaceutical industries.
Each model offers an onboard I/O configuration that can include digital, high-speed, and analog I/Os, including PT100/Thermocouple and weight/pressure measurement. Expansion modules enable local and remote I/O at distances of up to 1000 meters, making the new product a cost-effective solution for applications up to 512 I/Os.
Power features include 24 auto-tuned PID loops to control temperature, level, and pressure. Time-based and immediate interrupt support make device a natural for 'rapid response' applications such as packaging machines.
Built-in recipe capabilities are supported by Data Tables, which store the parameters required to control a specific process. Data Tables also enable the controller to store data logs to micro-SD card. The micro-SD card also stores application back-ups, and allows complete PLC cloning.
Communication options include Ethernet, cellular, and industrial protocols such as MODBUS, DF1 slave, BACnet, J1939, CANopen and more. In addition, the 'Protocol' utility allows Vision430 to communicate via almost any ASCII protocol. The unit can be directly accessed via mini-USB programming port, and remotely accessed using GPRS/GSM/CDMA and other IP networks for data acquisition and program download. Another major benefit is the ability to notify supervisors of critical information via e-mail and SMS, enabling real-time remote management.
The machine operator communicates directly with the application via the resistive analog touchscreen-or remotely, via the free Remote Operator utility-which displays data, color trend graphs, and attention-grabbing alarm screens. Display options are almost endless, with more than 1024 user-designed screens supported by 12 MB of memory for images and 1MB for fonts.
OEMs and machine builders profit from intuitive, all-in-one VisiLogic software that enables rapid hardware configuration, PLC, and HMI application programming. VisiLogic includes a full library of Drag & Drop function blocks for complex automation control tasks, such as PID, and a rich, free color library of industrial images.
