Large touchscreen HMI offers full PLC capability
PLC built into 12.1 in. HMI from Unitronics can support 24 loops and 1,000 I/O points.
The Vision1210 controller with integral HMI extends the size and capabilities of integrated units with a larger-than-ever 12.1 in., 65 K color-touchscreen. Unitronics says this controller is a perfect fit for the food industry since its IP66 rating protects it wherever spray and wipe down applications apply. A wide variety of on board I/O options can be added by simply snapping a module onto the back of the PLC.
With additional expansion modules allowing up to 1,000 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 m 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, and complete PLC cloning.
Systems integrators and end users can now rely on a single device since the Vision1210 can support 24 auto-tuned PID loops to control temperature, level, and pressure, while the 16-bit, 12.1 in., 800 x 600 pixel SVGA color touch screen displays data, color trend graphs, and attention-grabbing alarm screens. Display options are almost endless, with more than 1,024 user-designed screens, and up to 500 images per application. Internal memory holds 2 MB of application logic, plus 1 MB for fonts and 32 MB for images.
Communication options include TCP/IP Ethernet, cellular, and industrial protocols such as Modbus, DF1 slave, J1939, CANopen, and more. In addition, the system 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 such as packaging machines.
