With the hook you can catch dynamics like you do it with a crane. You should not take the name literally. Use the hook every time you have to transport dynamics that are not on a base.
Whether the hook is active or not is controlled by an output bit of the PLC. In case you activate the bit, the hook will catch all the dynamics with which it overlaps anywhere. Please note that the hook can also be activated externally by an on-/off-pawl.
Hooks are very suitable as ejector and stopper as well. Because the simulation of such elements is extremely difficult (you need to take into consideration weights, coefficients of friction, stabilities etc.), you need to help along in this case and switch on and off the hook in the right moment. If a PLC program code is also necessary for this, you shall arrange this one in the script (eventually also in OB 2 or OB 3). In simple cases a shifter can be of good use as well.
Hooks can be made turnable. Select the check box ‘turnable’ on the edit mask. Please read also the general information about turnable elements further below in this chapter.
