The LASTVAL Command
If the value in the report changes to ////, you can check the
measurement's value with the LASTVAL command. Give the
command in the terminal connection. When you use the raw
parameter, the measured value before any validation and the status
produced during validation are shown. When you use the
corresponding signal name, the validated value is shown.
LASTVAL [Measurement] [raw | Signal name]
where
Measurement = The name of the measurement as it is defined
in the MAWS setup file.
raw = The parameter that gives the status and the
value of the measurement before validation.
Signal name = The parameter that gives the validated value o
the measurement.
Example:
The measurement TAMeasQMH101_1 is defined in the setup file.
The command with the raw parameter produces the following
response:
/ > LASTVAL TAMeasQMH101_1 raw
Status:1 Value:20.490570
where
Status:1 = The value is valid.
Value:20.490570 = The raw value for the temperature
measurement is 20.49xxxx
When the value in the report changes to ////, you can check the value.
In the following case the probe is not connected:
/ > LASTVAL TAMeasQMH101_1 raw
Status:2 Value:-238.285549
where
Status:2 = The value is invalid.
Value:
-238.285549
= The raw value for the temperature
measurement is -238.285549, which means
the probe is not connected.
