Figure 109: Create a static NV manually.
3.
Enter a data point name and a programmatic name. The programmatic name is the
name of the static NV which is being created.
4.
Select a resource file. To create a SNVT, let the STANDARD resource file be
selected.
5.
Select a SNVT and a direction. If a non-standard resource file has been selected,
choose from one of the UNVTs.
6.
Choose a functional block, where this static NV shall be located in.
7.
Click
Create Static NV
. The static NV is created and appears in the data point list.
8.
Note, that the static interface of the L-Proxy will change as soon as static NVs are
added or modified in the data point manager. This change is reflected in a new model
number, which the L-Proxy will receive after the configuration download (see Section
6.5.2). Also note that the manually created static NVs are not bound automatically by
the L-Proxy Configurator. They simply appear on the device and need to be bound in
the network management tool.
7.9.10 Create External NVs
External NVs are not actually allocated NVs on the L-Proxy. Instead, the L-Proxy uses
polling to read data from and explicit updates to write data to external NVs. Since external
NVs do not affect the static NV interface of the L-Proxy, they can be used to extend an L-
Proxy’s interface configuration at run-time, where no LNS with dynamic NVs is available.
