The block of the first special function is shown:
Select your block (off-delay, see the next figure), and then

The B1 block previously connected to Q1 is automatically
connected to the uppermost input of the new block. Note that
you can only interconnect digital inputs with digital outputs or
analog inputs with analog outputs. The 'old' block will other-
wise be lost.
The off-delay block has three inputs. At the top is the trigger
input (Trg) you use to start the off-delay time. In our example,
the OR block B1 triggers the off-delay. You reset the time
and the output with a signal at the reset input. Set the off-de-
lay time at parameter T of the input Par.
