APPENDIX A
AWS330 CONFIGURATION
Vaisala Automatic Weather Station AWS330 is preconfigured, and there
is no need to make any configuration changes to take Observation
Display software into use.
Report Format
The report format used for communication between Observation Display
and the weather station is called SMSAWS. Lizard Setup Software
provides automated tools for generating reports in the correct format. On
some Lizard versions, you have to use the MetMan message template,
which is identical with SMSAWS format.
The following is an example of the SMSAWS report format:
(S:Station01;D:040607;T:182035;TA:61.12,0;RH:76.40;;DP:21.12;PA:1
008.42;PAA1:1007.35;PAX1:1008.23;PAM1:1005.90)
The format consists of elements having the following structure:
(S:STATIONID;D:YYMMDD;T:HHMMSS;TAG:value;TAG:value; ….
TAG:value)
- Left parenthesis marks the first character in the message.
- Right parenthesis marks the last character.
- Message body consists of pairs of variable identifiers (tags) and
values.
- There is a semicolon (;) between the (tag,value) pairs.
- There is no semicolon between the last (tag,value) pair and the closing
right parenthesis.
- Colon (:) separates tag and its value.
- First three (tag,value) pairs must contain station identifier, date, and
time.
- Remaining (tag,value) pairs may contain any variables in any order.
- Message may not contain the same tag twice.
- Tag "S" is reserved for station identifier.
