Assigning a value or clearing a value from a "flag" variable may lock the controller
Versions affected: All PAC firmware versions
Assigning a value to—or clearing a value from—a variable being used as a "flag" with the Flag Lock and Flag Unlock commands may prevent the locking chart from stopping. If you try to stop the strategy, the controller will become unresponsive as it waits (forever) for the locking chart to stop.
Use the Flag Lock and Flag Unlock commands with "flag" variables. (Don't set the value of the "flag" variable using any other methods or commands.)
