The settings of Serial Communications Unit are given in the following table.
The number from the barcode reader is separated into individual characters and bit strings for the char-
acter codes are stored in RecvDat[]. One element of the RecvDat[] array corresponds to one character
from the barcode. First, the AryToString instruction is used to convert the data to a text string
(RecvStringDat). Then, the STRING_TO_ULINT instruction is used to convert the data to an ULINT
integer (Code).
