14.1.27.1 Function 1: dnIn1 = dnIn2
This function compares two signals with regard to equality. It can, for instance, provide the
comparison "actual speed equals setpoint speed " (n
act
= n
set
).
Use C01672
to set the window within which the equality is to apply.
Use C01671
to set a hysteresis if the input signals are not stable and the output
oscillates.
