Retention
The function block does not recognize retentive data.
The interrupt program does not have any retentive data.
Example slope in easySoft 7
Rising edge operating mode
Cutting device at station 2. The interrupt is triggered with a pulse at function block input
I1. Device output Q1 is set in the interrupt program and the product is cut. Device output
Q2 is reset. The interrupt program Q01 passes marker 211 to the main program with Q1
and signals that the cutting device is active.
Once the product has been cut at station 2, there is a rising edge at input I1 of the base
device. Processing must be initiated.

Description
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.
Function block parameters and con-
stants can be edited on the device.
Used to select device inputs I1
through I8 as a trigger for the inter-
rupt
Clicking on the button will open the
interrupt routine in the Programming
view
Note
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.
