12.13.30 Insert Branch
Symbol:
Shortcut: <Ctrl> + <V>
This command (category 'FBD / LD / IL') branches the current execution line within a
network in FBD/LD.
The current line will be split into two "subnetworks": An additional line will be drawn
"below" the existing one. In online mode the two subnetworks after a branching point
will be executed one after the other from up to down.
If you drag the "branch" element from the toolbox or another position within the
network, you will get indicated all possible insert positions by grey position markers.
A branch can be inserted at the input connectors of boxes which are not positioned in
a subnetwork, at the output connectors (cursor position 4) of a box if that is not
connected (also indirectly) to the input of another box within a subnetwork, at the
connector between contacts and coils (cursor position 10), or at a contact (cursor
position 8). A branch cannot be inserted inside of "OR"ed contacts groups and inside of
multiple assignment groups.
Each subnetwork gets an own "marker", an upstanding rectangle symbol, which serves
as a possible cursor position (11) for selecting the subnetwork.
Abb. 118 Subnetwork markers in FBD network
Each subnetwork can get another branching, thus multiple branches and thus a widely
ramified construction of "subnetworks" is possible within the main network. For
adding branches to branches see the commands: Insert Branch above and Insert
Branch below.
For general information on branches see Branches in FBD/LD/IL.
The command is not available in IL editor. Networks with branch elements cannot be
converted to IL.
Note: Concerning the display options for the components of a LD / FBD network
notice the settings in the 'FBD/LD and IL editor Options'.
