FW-CW Firmware for Checkweighing

FM-CW Firmware Weight Tolerance Checking
FM-CW Firmware Weight Tolerance Checking

Special firmware for OEM systems for industrial automation.

Weight control through the static or dynamic weighing of pre-packaged products on a conveyor belt. Increased processing of the number of packages per minute by the advanced firmware and filter functions. Fully programmable receipt print layouts.

This firmware applies to our weight indicators of the types HP(R)-Ultra, VPI-U, HPR-TouchHP-Touch and VPI-U-Advanced.

FW-CW Firmware for Checkweighing

Weight control through the static or dynamic weighing of pre-packaged products on a conveyor belt

Properties / functions

  • static or dynamic weighing, with management of pack detection photo cell
  • dynamic weighing with two START/STOP photo cells
  • static or dynamic weighing without photo cell (for Pick and Place lines)
  • tolerance check:
    – by target, through articles database, with setting of 3 tolerance thresholds, for the physical division of the packs into 7 different groups
    – by programmable weight thresholds (min/max), with articles dabatase
    – by weight thresholds (min/max), through a quickly entry.
  • calculation and printing of the statistics and of the standard deviation of the executed weighs
  • static or dynamic autozero function of the belt (up to 2% of the flow) after a programmable number of weighs
  • advanced management of bar codes, with the possibility of storing, processing, and printing 5 different codes
  • automatic printing/clearing of the partial total after a programmable number of weighs
  • printing with each executed weigh and eventual automatic storage into the alibi memory
  • completely programmable printouts, for compatibility with any ASCII printer manageable through the serial port
  • database of 1000 articles with alphanumeric description, target and programmable tolerance thresholds
    setting the density coefficient, for every article, for weighing in ml
  • programmable preset tare and activation delay of the expeller for each article
  • management of belt speed through analog output, with programmable value for articles
  • article selection through reading of bar code

I/O-functions

  • cycle activation, RESTART / RESET cycle and START / STOP weigh through external inputs
  • management, through a cadence photo cell, of the cadence belt, for optimising the number of packs per minute weighed by the instrument
  • management of the automatic expulsion or stopping of the belts for manual expulsion or weight correction
  • programmable alarm activation time and tolerance indication; possibility of connection to control light
  • activation of the line second speed through an external input, with automatic recalculation of the weighing time (only for weighing with two photo cells)
  • analog output (optional) proportional to the weight or managing the belt speed, with programmable values for each article
  • serial communication protocol for programming recipes, products and cycle management
  • serial communication protocol for programming the articles and managing the cycle
  • external Profibus interface (optional), for programming the articles and cycle management
  • bluetooth connection (optional) for programming recipes, products and cycle management
