This mode only knows the internal feedback signal (= signal level at the DO terminal) used to
test the F-DO output transistors.

Test sequence for test stop mode 1
This monitoring function can be used to verify the ability of the F-DO output transistors to
switch (off) - even if the actuator itself does not provide a feedback signal.
Before testing the F-DOs, the F-DIs are tested by switching off the power supply (L1+, L2+).
The system waits for the parameterized delay time p10001 (SI delay time for test stop)
between the individual test steps before the expected response is checked.
