This controller is a perfect fit for the food industry- with its IP66 rating, this unit is ideal wherever spray/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 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 1000m 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, 12.1”,800X600 pixel SVGA color touch screen displays data, color trend graphs, and attention-grabbing alarm screens. Display options are almost endless, with more than 1000 user-designed screens, and up to 500 images per application. Internal memory holds 2MB of application logic, plus 1MB for fonts and 32MB for images.
Communication options include TCP/IP 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 such as packaging machines.

Special Features

  • Flexible PID: Up to 20 built-in PID loops, including internal auto-tune, ramp-soak programmer and bumpless transfer. Use Vision’s PID loops to economically and efficiently combine accurate process control with the flexibility of a PLC.
  • Data Tables: Use Vision’s smart data tables to log dynamic data and to store production recipes. 120K for recipes parameters, datalogs, etc. and 192K for read-only data, ingredient names, etc.
  • Easy Scrolling between Recipes: Simply scroll between pre-programmed recipes or menus, using the panel’s arrow keys. This enables you to choose and activate a desired task via the HMI - immediately, on-site.
  • Image Library: Easily design your graphic displays using the Vision’s extensive image library.
  • Time-based Control: Do you need a specific task to be performed at a specific time and date? Simply mark the hour, date or weekday in the PLC software—and you have created time-based control in 3 clicks.
  • Information mode (touchscreen): Press the touchscreen for a few seconds to enter the PLC’s Information Mode, providing you with powerful diagnostic capabilities.
  • Shaft-encoder Inputs: Use the controller’s integral 10kHz inputs as high-speed counters, frequency measurers, or to directly connect to shaft-encoders.
  • PWM Outputs: Control stepper motors or PID-based applications, via PWM, with the M90/91’s onboard PWM outputs (model-dependent).
  • Virtual Keypad: Application requires data entry? The Vision's virtual keypad pops up automatically.
