In case of defined situations (e.g. a sequence error or a not-finished product) the request for stop of a conveyor of a production line is sent to the conveyor controller. It is a software module, which is running on a computer connected to a conveyor PLC with a serial line or via Ethernet network.

The conveyor can be stopped in these cases:

  1. Sequence error
  2. Not-completed product
  3. NOK result of any operation
  4. Timeout for the cockpit on workstation expired (the product was not finished on a station within the time limit)
  5. Timeout for the inactivity on workstation expired (no action taken on a station within the time limit while the product was not finished)
  6. Cockpit is sent to rework:
    1. When scanned a barcode “Send to rework”
    2. Automatically when NOK result of any operation
