After activation of the FB, any button set to TRUE is detected as an invalid input setting leading
to an error. The FB detects when the divergence of the input signals exceeds 500 ms.
Error behavior In the event of an error, the S_TwoHandOut output is set to FALSE and remains in this safe
state.
The error state is exited when both buttons are released (set to FALSE).
