Third-party device parameters

Third-party device parameters
Only valid for partners that are not configured in the STEP 7 project.
● Network node type third-party device / Network node type third-party device (red.)
Configure the network node type of the third-party device that is accessible via a
connection or via two redundant connection paths:
– Master station
– Node station
– Station

This is the bundled transfer of events according to data types typical for DNP3. First
the existing binary events are sent, then all analog values and finally all counted value
changes. This makes the frames somewhat more compact and transmission more
efficient.
Events are transferred strictly chronologically. The optimizing effect of grouping into
blocks of the same data type as described in the DNP3 specification (see above) is
lost.
This form is primarily intended for control systems that archive events strictly
chronologically.
(Master)
For modules that act as a node station, the following applies:
The interface in the direction of the master station is configured as a "node station".
The interface in the direction of the lower-level network is configured as a "Master
station".
