Adding More
Rails
Each island is graphically displayed as one or more segments on DIN rails. The first
segment is called the primary segment. Every island must, at a minimum, have a
primary segment. Additional extension segments are optional. An island can support
up to six extension segments.
The Advantys configuration software uses a convention where each segment in an
island appears on its own rail. (The software actually refers to the segments as rails.)
This may be different from the actual physical island, where multiple segments may
be installed on separate DIN rails or on the same rail.
Here is an example of an island with a primary segment and two extension
segments:
To add an extension rail to a logical island, place an STB XBE 1000 EOS module at
the end of the last segment, then select an STB XBE 1200 BOS module from the
Accessories group in the catalog browser. A new rail with a BOS module on it will
automatically appear in the island editor. A cable will connect the BOS module to the
previous EOS module.
