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
PROJECT TREE,
LMS…, P
ARAMETER,
B
ASIC PARAMETERS,
area M
EASUREMENT.
• 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.
