Measured value output
For the measured value output, the LMS1xx supplies measured values to one of the
interfaces. It is prerequisite for this data output that the LMS1xx is in the measurement
mode. There are two ways you can start the measurement mode:
start via SOPAS ET
P
ROJECT
TREE
, LMS…, P
ARAMETER

EASUREMENT
start via telegram
Recommendation
After the measurement mode is started the LMS1xx needs a little time to reach the status
“Ready for measurement”. You should therefore query the status of the LMS1xx using the
sRN STlms
telegram.
Then request measured data by using a telegram on the interface from which you want to
receive measured data. There are two possible ways of doing this:
Exactly one measured value telegram can be requested using the
sRN LMDscandata
telegram — the last scan measured is transferred.
Measured data can be continuously requested using the
sEN LMDscandata
telegram —
measured data are then transferred until the measured value output is stopped using
the
sEN LMDscandata
telegram.
