ASCII Configuration – ASCII Parsing
Click the
ASCII Parsing (Optional)
button at the bottom of the ACII Configuration page to access the
ASCII Parsing Configuration page for this device.
1)
Max Number of Fields:
This indicates the max number of values the ASCII data can be parsed
into (up to 50 values per message).
2)
Min Number of Fields:
This indicates the min number of values the ASCII data can be parsed
into (up to 50 values per message). If the min number isn’t met, then it will be flagged an error.
3)
Parsing Delimiter:
This option is used if the fields of the ASCII message are separated by a single
Delimiter, such as a “,” character. If a single Delimiter does not separate the fields, select this
field to be UNUSED and then use the character length fields below to parse the message.
4)
Start Location & Length:
a.
If a Parsing Delimiter is used, the
Start Location
will be the first character of the data
between the Delimiters. The
Length
will be the number of characters from the Start
Location to form the value. If the
Length
is 0, the gateway will read the entire parsed
message from the
Start Location
to the next delimiter.
b.
If the Parsing Delimiter is unused, then the
Start Location
will be the first character of
the entire message received. The
Length
will be the number of characters from the Start
Location to form the value. If the
Length
is 0, the gateway will read the entire parsed
message from the
Start Location
to the end of the ASCII message.
5)
Data Type:
Select the data type of the parsed value.
6)
Internal Tag Name:
Enter a name to reference this tag within the gateway. This value is used on
the display page and the mapping page.
