If "ERRCODE" <> DW#16#0000 0000" following an FB call, you will need to call the FB again
with "RESET = TRUE" to reset the error information in the FB.
Note
Acknowledging the error of the optical reader
By calling the FB with "RESET = TRUE", you only acknowledge error displays of the FB. To
acknowledge errors of the optical reader (e.g. "Transmit error"), you must set the "RES" bit of
the control byte.
