A large food plant producing bakery product (export company), had demand for the automatic product registration system. This system intended to be a part of the complex product tracking system along the production line.
Packing machine is the last element of the production line. The number of packaging cycles during one shift is univocal and objective index of the product manufactured.
To compare production plan and actual product volume produced, it was necessary to have an objective (not depending on staff) product registration system, with reporting and long-term (3 monthes) report storage functions.
Packing machine control panel, with::
Packing machine operation data were collected “manually” – by viewing counter value on the HMI panel.
The reading had to be read promptly, because PLC program stored only one current pack counter (for the last completed batch of certain recipe, before recipe change). This made registration process inconvenient and unreliable.
it was possible, however, to re-program HMI panel to have more entries for pack counters, but this would solve the task only by half – the operator still would go and read manually this data and then manually transfer it into accounting system. HMI panel itself can not help in organizing required data and integrating with enterprise IT system.
So an ideal thing for this project was some task – oriented solution, which would allow to automatically read and register production counters from PLC program and send them to management level.
Intrinsic features of WebHMI leveraged fast and easy solution for the task of logging and reporting packing machine operation:
WebHMI’s features leveraged quick and efficient solution of the task – to provide objective (“human-factor” free) product quantity registration reports and show them in handy format on any computer in LAN:
