How is the process interlock with barcode scanner done with CFX about cfx HOT 1 OPEN

If your device is internally capable of reading the barcode/identifier of a production unit (via a barcode scanner or RFID reader), then prior to processing, you would 1) Read the unit barode. 2) Send a CFX request to an upper level software system (like MES) using CFX.InformationSystem.UnitValidation.ValidateUnits 3) Receive back the response. If ok, continue to process the unit as usual. If not ok, prevent processing and allow operator to correct then try again.

If your device cannot read a barcode, you can acquire the barcode either from Hermes, or from a CFX compliant barcode reader by subscribing to the CFX.Sensor.Identification.IdentifiersRead. message or by making an IdentifyUnitsRequest/Response call to the CFX scanner. Then you would make the ValidateUnits message as described above.
