“SHEF Fixed” is a special version of the SHEF format where numbers are fixed to seven decimal
points.
SSP Format
“SSP” is a binary format following the specifications of the Sutron Standard Protocol, which is
useful when transmitting to XConnect or Tempest master stations.
If you are interested in knowing more about the low-level details of the protocol, please contact
Sutron Customer Service.
Text Format
The Text format is an ASCII, human readable format intended to convey the current status of the
sensors, quality, and alarm state. It is similar in format to the “SHOW” command, and is
intended for alarm messages. It’s also the default format for SMS Alarm messages when
SMSAlarmsEnable is set to “Yes”. Sensor readings are separated by <CRLF>, while fields in the
sensor data is separated with a space.
An example of a Text format message:
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.
