4.
If the option for initializing the carrier with a status code has been selected at the HMI, this is executed
now.
5. If the status code from the order data record corresponds to a „start condition“ from the t ransition table
of the HMI, the station’s PLC will start the function sequence of the CP application module Measuring. If
not, the carrier will be released by the stopper and transferred to the next station.
6. If the status code from the order data record corresponds to a “start condition” from the transition table
of the HMI, the PLC of the station will take the parameters assigned to the “start condition” from the
transition table. The parameters of the CP application module Measuring are: upper limit value and
lower limit value.
7. The station’s PLC starts the function sequence of the CP application module Measuring:
•
The signal lamp of the station is flashing orange as long as the function sequence has not been
finished yet.
•
The station records the measured values of the two distance sensors, calculates the actual
measured value of difference and emits it at the HMI device.
•
It checks if the actual measured value of difference is in the parametrized limit range between
upper and lower limit value.
It outputs the result of the evaluation as binary information at the HMI device and at the signal
lamp:
Bad:
If the actual measured value of difference is below the lower limit value or above the upper limit
value, then the front cover does not meet the quality standard. The signal lamp is flashing red and the
front cover will be treated as bad part in further order processing. The new status code corresponds
to the status code “final state NOK” in the transition table of the HMI.
Good:
If the actual measured value of difference is within the defined limit range, the front cover meets
the quality standard. The signal lamp is flashing green and the front cover will be treated as good
part in further order processing
. The new status code corresponds to the status code “final state
OK” in the transition table of the HMI.
8. The function sequence of the CP application module Measuring is finished.
Special case: The function sequence has been finished with an error. :
At the HMI, a window opens up. The error text is displayed in the window, and the system operator can
restart the function sequence of the CP application module Measuring, ignore or cancel it (further
information is provided in the operating instructions of the basic module) by pressing the buttons
“Repeat”, ”Ignore”, ”Cancel”.
9. Then the station’s PLC takes the status code “final state NOK resp. OK“ from the HMI’s transition table
and writes it with the RFID read-write head as the new status code on the transponder of the carrier.
10. If no carrier blockade has been recognized in front of the station, the carrier will be released by the
stopper and transferred to the next station.
