M_AcknowledgeWarning

This method acknowledges a warning in the Admin-Tags. Warning[].Trigger is set to FALSE and the value from Admin.PlcDateTime is entered in Warning[].AckDateTime. The method returns TRUE if the warning was found and acknowledged successfully. The warning remains in the Warning array until it is pushed out of the array by the next warning.

So that a valid timestamp can be entered, the function block PML_AdminTime should be called cyclically in the program.
