The newest POU is inserted at the selected position:
• If an input is selected (Cursor Position 2), then the POU is inserted in front of this
input. The first input of this POU is linked to the branch on the left of the selected
input. The output of the new POU is linked to the selected input.
• If an output is selected (Cursor Position 4), then the POU is inserted after this
output. The first input of the POU is connected with the selected output. The
output of the new POU is linked to the branch with which the selected output was
linked.
• If a POU, a function, or a function block is selected (Cursor Position 3), then the old
element will be replaced by the new POU.
• As far as possible, the branches will be connected the same way as they were
before the replacement. If the old element had more inputs than the new one,
then the unattachable branches will be deleted. The same holds true for the
outputs.
• If a jump or a return is selected, then the POU will be inserted before this jump or
return. The first input of the POU is connected with the branch to the left of the
selected element. The output of the POU is linked to the branch to the right of the
selected element.
• If the last cursor position of a network is selected (Cursor Position 6), then the POU
will be inserted following the last element. The first input of the POU is linked to
the branch to the left of the selected position.
• All POU inputs that could not be linked will receive the text "???". This text must be
clicked and changed into the desired constant or variable.
• If there is a branch to the right of an inserted POU, then the branch will be
assigned to the first POU output. Otherwise the outputs remain unassigned.
