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 out-
puts or analog inputs with analog outputs. The ’old’ block
will otherwise be lost.
The off-delay block has three inputs. At the top is the trig-
ger 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-delay time at parameter T of the input Par.
