Parameter set
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 eval-
uated. If the checkbox is disabled
instead, the function block will be
enabled and function block input EN will
not do anything. This parameter ensures that when exist-
ing programs are copied, the func-
tionality 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 Function block parameters and constants
can be edited on the device.
