Issue Description
With Logix controllers, the following functional issue exists:
Functional Issue – Incorrect Sequential Function Chart (SFC) forcing when performing an online edit of a SFC.
This problem arises when you combine online editing of SFC routines, with forcing on the same routine. If SFC forces are present, when the edits are assembled or cancelled, the force information can become corrupt. Once corrupted, attempting to Remove all SFC forces will appear to be successful while, in fact, the forces will still be active.
Temporary Workarounds
To avoid this problem, insure there are no SFC forces in either version of the routine before assembling, canceling, or finalizing your edits.
