ASCII Configuration – ASCII Parsing Examples
Example #1 - Parsing a message using the Parsing Delimiter option:
In this example, we are separating the fields in the string “12.25,SP100,temp setpoint” by a comma
delimiter. The first value is being parsed into a float data type, while the second and third values are
being parsed into a string data type. Since the Min Number of Fields is 3, all 3 fields must be present for
the message to be considered valid and processed. The output is seen below:
Example #2 - Parsing a message without the Parsing Delimiter option:
In this example, we are separating the fields in the string “12.25,SP100,temp setpoint” using the start
and length fields. The first value is being parsed from the 1
st
character for a length of 5 and stored into a
float data type. The second value is being parsed from the 7
th
character of the entire ASCII message for a
length of 5 characters and stored into a string data type. The third value is being parsed starting from
the 13
th
character for the rest of the remaining characters and stored into a string. The fourth value
contains the entire ASCII message and is stored into a string. Only the first field needs to be present for
the data to be considered valid and will be processed. If less than field 1 is present, the message will not
be parsed and will be flagged an error. The output is seen below:
