Assemble Edits with Caution

When you assemble edits to your program while online, the original program that existed before the changes were made is deleted. As a result, if the edits you assemble cause a fault on the primary controller, the new primary controller also faults after the switchover. Also, when you assemble edits in the primary controller, the edits are also assembled in the secondary controller.
Before you assemble any edits to your program, test the edits to verify that faults do not occur.
  1. In the Controller Organizer, open the routine to edit.
  2. Modify your routine.
  3. Select Verify Routine.
  4. Select Accept Pending Program Edits.
    IMPORTANT:
    Even if you have not enabled the Retain Test Edits on Switchover property, faults can still occur on the primary and secondary controllers if the edits are assembled.
    The Retain Test Edits on Switchover property affects only edits that are being tested. The Retain Test Edits on Switchover does not affect the redundant controllers that are running assembled edits.
