List of all possible SFC flags

“Enabled” : The SFC flag is enabled and therefore included when processing.

“Declare” : The SFC flag is automatically declared.

If “Declare” is selected, but “Use” is not, then the variable is declared, but the flag has does not have any function when processing is performed.

Note: If you have manually declared an SFC flag variable, then you have to deselect the declaration for this flag in “SFC Settings”. Otherwise the automatically declared flag overwrites the manually declared flag.

An automatically declared variable is visible in the declaration part of the SFC editor only in online mode.

“Use defaults”

: The settings available here in the dialog overwrite the “SFC Settings” which are defined within the individual POUs.
