Parameter set
 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 function
block.
Parameter display
+ Call enabled
Constants can be edited on the
device, as can function block para-
meters when using the EDP pro-
gramming language.
