Relay ladder
Test edits
When you accept your pending edits, the software downloads them to the
controller and marks them as test edits but the controller continues to execute the
original logic. You then manually switch execution to the test edits or back to the
original logic (test and untest the edits).
In relay ladder, if you delete a rung the software immediately marks it as a test
edit (upper-case 'D' character).
