10.2.4 Read scan data
The measured value output is started using this message. It is a prerequisite for this action
that the LMS is in the “Measurement” status. For this purpose the measurement mode
must be started, there are two ways you can undertake this action:
•
start via SOPAS ET

•
start via message (see section 10.2.1 “Start measurement” on page 77 )
Single or continuous measured value output
There are two ways of requesting measured value output (see section 3.7.3 “Measured
value output” on page 27 ):
•
Exactly one measured value message can be requested using the sRN LMDscandata
message — the last scan measured is transferred.
•
Measured data can be continuously requested using the sEN LMDscandata message —
measured data are then transferred until the measured value output is stopped using
the
sEN LMDscandata message.
