Description Note
Function block release by
EN is necessary
If this checkbox is enabled, the state
of function block input EN will be
evaluated. If the checkbox is dis-
abled instead, the function block will
be enabled and function block input
EN will not do anything. This parameter ensures that
when existing programs are
copied, the functionality of the
function blocks that are carried
over will be retained. The para-
meter will be automatically set
to 0 or 1 depending on the func-
tion block.
