yes i could do that although i will end up with hundrededs of networks with only 1 rung on each.

I dont think this is the way to go if it can be avoided.

There are rules for LAD to follow even in TIA.More you can find in the online manual.To avoid those time consuming tasks, USE STL .

Rules for branches in LAD


The following rules apply to simultaneous branches:

1-A simultaneous branch can only be inserted if the main branch already contains an LAD element.

2-Simultaneous branches are opened downwards or are connected directly to the power rail. They are terminated upwards.

3-Simultaneous branches are opened after the selected LAD element.

4-Simultaneous branches are terminated after the selected LAD element.

5-To delete a simultaneous branch, you must delete all LAD elements of this branch. When the last LAD element is removed from the branch, the rest of the branch is also removed.
