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.
Parameter display
+ Call enabled
Function block parameters and con-
stants can be edited on the device.
Edit interrupt routine
Clicking on the button will open the
interrupt routine

6.2.1.4 Other
Retention
The function block does not recognize retentive data.
The interrupt program does not have any retentive data.
Monitoring the interrupt load
In total, no more than 8 interrupt sources are allowed to be processed in a single pro-
gram. The valid interrupt sources are the IC, IE, IT interrupt function blocks and the CF,
CH, and CI high-speed counters that are directly connected to the device inputs. For
more information, please refer to → "CF - Frequency counter", page 224, → "CH - High-
speed counter", page 230 , → "CI - Incremental counter", page 237 as well.
