Output of measured values
For output of measured values, the device supplies measured values at one of the data
interfaces. Prerequisite for data output is that the device is in measurement mode. You
have two options for starting the measurement mode:
•
Start in SOPAS ET (

section)
•
Start via a telegram (see telegram listing no. 8014631 under
).
NOTE
After starting the measurement mode, the device needs some time to reach status 7
(“measurement”). That is why you should request the status of the device with the sRN
STIms telegram.
Then request measured data via telegram at the data interface from which you want to
receive measured data. This can be achieved in two ways:
•
The request of exactly one measured value with the sRN LMDscandata telegram –
the last measured scan is transmitted.
•
Continuous request of measured data with the sEN LMDscandata telegram –
measured data is transmitted until the output of measured values is stopped with
the sEN LMDscandata telegram.
