A network can be set in "comment state", which effects that the network is not
processed but displayed and handled like a comment.
On a currently selected network (cursor position 6) the default commands for copying,
cutting, inserting and deleting can be applied.
Note: The right mouse click (cursor position 6) being executed over a title, comment
or label will select this entry only instead of the whole network. So the execution of
the default commands will have no influence on the network itself.
To insert a network, use command Insert Network or drag it from the toolbox. A
network with all belonging elements can also be copied or moved by drag&drop
within the editor.
Notice the possibility to create "subnetworks" by inserting "branches".
RET network:
In online mode automatically an additional, empty network will be displayed below
the existing networks. Instead of a network number it is identified by "RET". It
represents the position at which the execution will return to the calling POU and
provides a possible halt position.
Assignment in FBD/LD/IL
Depending on the selected position in FBD or LD an assignment will be inserted
directly in front of the selected input (Cursor Position 2), directly after the selected
output (Cursor Position 4) or at the end of the network (Cursor Position 6). In an LD
network an assignment will be displayed as a coil. Alternatively drag the assignment
element from the toolbox or copy or move it by drag&drop within the editor view.
After insertion the text string "???" can be replaced by the name of the variable that is
to be assigned. For this via the
button you can use the Input Assistant.
In IL an assignment is programmed via LD and ST instructions. See in this context:
Modifiers and operators in IL.
Jump
Depending on the selected position in FBD or LD a jump will be inserted directly in
front of the selected input (Cursor Position 2), directly after the selected output (Cursor
Position 4) or at the end of the network (Cursor Position 6). Alternatively drag the jump
element from the toolbox or copy or move it by drag&drop within the editor.
After insertion the automatically entered "???" can be replaced by the label to which
the jump should be assigned.
In IL a jump is inserted via an JMP instruction. See in this context the description of the
operators and modifiers.
