removed, the rung's status area returns to the state it was in prior to

containing the trigger you want to remove. See Selecting
Rungs," section 2.2, or Selecting Instructions," section
2.7, for more information.
Step 2. From the Online menu, select Capture Trigger. Move the
mouse to the right to display the Capture Trigger menu.

The Editor also clears triggers when the selected rung is scrolled
out of view on the screen or when an online program is closed.
5.12 Setting and Forcing Variables in Ladder
Programs
You can set and force variables in ladder programs to put them
temporarily in a known state for debugging purposes. To set, force,
and unforce variables, you must have an online program window
open. You can set or force any global variable in the configuration or
any local variable present in a task that is loaded into the rack.

You can force only simple variables. You cannot force
elementĆindexed or bitĆindexed variables. For example, you cannot
force variables like: vat.13, array_var[11], array_var[index_name],
array_var[11].12, or array_var[index_name].bit_name.
