Processing of receive data
The data stored in RecvDat[] is a bit string consisting of character codes that correspond to the individ-
ual character values of the bar code. One array element of RecvDat[] corresponds to one bar code
character. First, the characters are converted to the character string RecvStringDat by using the Ary-
ToString instruction. Next, RecvStringDat is converted to the ULINT integer code by using the
STRING_TO_ULINT instruction.
