SMSAlarmsEnable
When SMSAlarmsEnable is “Yes” and SMSTxList has a phone number in it, the 8310 shall also
send alarm messages via SMS. The SMS message is human readable, and includes the station
name so the user does not need to know the station identified by the phone number. The time
is also included to account for the delays in delivery. The date is not included as the delays are
expected to be short. The alarm transmissions format of what sensor data gets sent is based on
whether the user set AlarmData to “All Sensors”, or “Single Sensor”.
An example of the Text format used for SMS alarm messages:
RTU01 12:22<cr><lf>
STAGE 4.55 G H+R+<cr><lf>
RAIN 2.0 G OK<cr><lf>
The message begins with the station’s name (“RTU01”) and the current time in HH:MM (12:22)
format followed by a list of sensor readings containing the name of the sensor (“STAGE”), the
value (“4.55”), the quality (“G”), and the alarm status (“H+R+”).
In the above example "H+R+" indicates that STAGE is experiencing a high limit and high rate of
change alarm, while the “OK” status for RAIN indicates that it is within expected limits.
Quality codes:
G: Good quality
B: Bad quality
U: Undefined quality
Alarm codes:
H: High limit exceeded
L: Low limit exceeded
R: High Rate of change
OK: Normal
A “+” after a code indicates that the sensor has just entered that state, while a “-“ after a code indicates
that the sensor has just exited that state.
CAUTION: SMS alarm transmissions is limited to 160 bytes of data. Users will have to limit their
data sent per transmission or else the SMS message may not be able to contain it all.

by the user using SMS, the command line, or by ringing the cell modem
(CSDShoulderTap=Yes), then it should send an “STAP failed (could not connect)” SMS
