PLC + HMI in One Unit: Full Functionality

Industrial control processes can enjoy full PLC functionality with a larger color touch screen

With its IP66, NEMA4X rating, this unit is ideal wherever spray/wipe-down applications apply. A wide variety of onboard I/O options can be added by simply snapping a module onto the back of the programmable logic controller (PLC). With additional expansion modules allowing up to 1024 I/O, these configurations include digital and analog inputs and outputs, high-speed I/O, PT100/Thermocouple capabilities, and weight measurement. They can be mounted locally or remotely, up to 1,000 meters from the controller.

This power-PLC is equipped with a built-in USB programming port, recipe capabilities, Micro SD card memory storage for data logging and back up, complete PLC cloning and more.

Systems integrators can now rely on a single device. The Vision1210 can support 24 auto-tuned PID loops to control temperature, level and pressure, while the 16-bit, 12-in. 800-by-600 pixel SVGA color touch screen displays data, color trend graphs, and attention-grabbing alarm screens. Display options are almost endless, with more than 1,000 user-designed screens, and up to 500 images per application. The internal memory holds 2MB of application logic, plus 1MB for fonts and 32MB for images.

Communication options include Ethernet, cellular and industrial protocols such as MODBUS, DF1 slave, J1939, CANopen and more. In addition, the Vision1210 can be taught to communicate via almost any device-based protocol. The controller is also capable of time-based and immediate interrupts, making it a natural for rapid response applications.

Unitronics’ free VisiLogic software provides one user-friendly environment for hardware configuration, modular Ladder application development and HMI design, including a color library of industrial images. The brand also offers free technical support for all of its products.

The Vision1210 reduces overall system costs by minimizing hardware requirements, saving cabinet space and exempting the user from setting up Panel-PLC communication.
