Logic programming – Function blocks
Reset
A falling edge on the Reset input restarts the start sequence. An active inch mode is
stopped and the function block back goes into Waiting for start mode. The Enable
output as well as the Forward active and the Backward active output will become
Low while the Startup active output will become High.
Startup active output
The Startup active output is Low during the start sequence (waiting or release time
is running) or if inch mode is active (the Enable output is High). The Startup active
output can be used to lock other parallel Start warning function block instances. To
this purpose, connect the Startup active output via a CPU marker to the Lock input
of the other function block instance (see Figure 171).
Waiting time active output and Release time active output
These outputs indicate whether the waiting time or the release time is active.
