6.2.1. The four operating modes
Operating mode M1
Measured value recording is inactive. “OFF” is shown in the second measured
value row. The STOP symbol is shown.
In this operating mode (data logger delivery state), the power consumption is
minimal because measured values cannot be requested or shown.
Operating mode M2
Measured value detection is active. The measured values which have been con-
figured in the SmartGraph software are shown in all three measured value rows
at the selected sensing rate.
In this operating mode, data recording is inactive; the displayed measured
values are not saved in the memory. The display for measured value recording
thus shows STOP (no data recording).
Operating mode M3
Measured value detection and data recording are active. The measured values
which have been configured in the SmartGraph software are shown in all three
measured value rows at the selected sensing rate.
Additionally, in this operating mode, up to twenty measuring channels, which can
be selected in the SmartGraph software, are stored in the measured value memory.
The display for measured value recording thus shows REC (data recording).
Operating mode M4
Measured value detection and data recording are active; but measured value
display is inactive.

Measured values are not shown in any of the three measured value rows. Still,
in this operating mode, up to twenty measuring channels, which can be selected
in the SmartGraph software, are stored in the measured value memory. The
display for measured value recording thus shows REC (data recording).
6.2.2. Network function (M51)
Requirements for connecting over a IPv4 network.
To automatically identify the IP configuration of a data logger (which has received
an IP address in the IP network via DHCP for example), it is necessary that UDP
broadcasts are allowed through the network.
b
Note: Based on their concept, UDP broadcasts do not operate
through a router (NAT), but instead only within its own network. If
the data logger is outside of the network, using fixed IP addresses through a
system administrator is highly recommended.
Connect to the network
If the data logger is connected to a local network and the network function is ac-
tivated, then software configuration and data reading from the data logger can
be carried out over the network.
A signal which is broadcast from the data logger over UDP allows the SmartGraph
software to automatically find the measuring device in the local network.
The first time that the data logger is connected to the network (add network
device), it may be necessary to adjust the data logger's network settings to the
configuration of the available network in the SmartGraph software. The factory
preset is DHCP.
Further information about the network function is provided in the
software manual which you can open from the help function
of the SmartGraph software.
With the professional version of the SmartGraph software, it is also possible to
retrieve and log current and saved measured values of the data logger in ad-
justable request intervals over the network.
Use in network mode
For continuous use of the network card, the data logger must be mounted on
a wall. There must be a free air convection within a gap of a half metre and the
zone must not be interrupted by external sources of convection (fans, lighting
etc.).
Power supply in network mode
Using the network card, which is built into the data logger, raises the power con-
sumption of the measuring device.
When the device is running on batteries alone and not connected to an external
power supply, it automatically deactivates the network function after 12 minutes
pass without communicating with the network. In this case, the network function
must be restarted by an external power supply either manually or automatically.
b
When using the data logger in LAN mode, the power should thus
be supplied by the USB power supply.
In the optionally available PoE design, the data logger can have its power
supplied directly over the network connection.
