You might need to adjust the TCP/IP configuration of the Ethernet interface so that a
connected PC (client) can communicate with the device via Ethernet.
NOTE
If you change the parameters of the Ethernet interface via the Ethernet interface, you
must first save the data permanently to non-volatile memory and then restart the
device.
3.5.3
Output of measured values
A fundamental distinction must be made between continuous and triggered output of
measured values.
NOTICE
A permanent measurement (with or without output of measured values) reduces the
service life of the laser diode and thus the device.
There are 3 possible ways to extend the service life of the laser diode:
1
Disconnect the device from the voltage.
2
Use software trigger options for laser control with the
sMN LMCstandby
telegram command
(hexadecimal:
734D4E204C4D437374616E646279
). Do not
reactivate the laser until immediately before sending the request for measured val‐
ues with the Start Measurement telegram
sMN LMCstartmeas
(hexadecimal:
734D4E204C4D4373746172746D656173
, login on device not necessary).
3
Use hardware trigger options for laser control.
3.5.3.1
Continuous output of measured values
With continuous output of measured values, once the device has received an
sEN
LMDscandata 1
telegram (hexadecimal:
73454E204C4D447363616E646174612001
)
requesting measured values, measured value telegrams are sent until the output of
measured values is terminated by the stop telegram
sEN LMDscandata 0
(hexadeci‐
mal:
73454E204C4D447363616E646174612000
). When the output of measured values
stops, the motor continues to turn normally, the laser diode remains switched on, and
measurement data continues to be generated and processed inside the device. Laser
control must be set to “free-running”.
