Hysteresis
The hysteresis function avoids the high-frequent switchover of the measurement channel value. The
hysteresis can be adjusted for each input measurement channel individually and can be used for
further processing.
1.
Click ‘Measurement Sources’ in the Toolbox.
2.
Drag the ‘Hysteresis’ computed source from the Toolbox and drop it on ‘Computed Channels’ in
the DDU 7 Project Tree.
A ‘Hysteresis Wizard’ opens.
a)
Choose input measurement channel.
b)
Choose unit group and unit of output.
c)
Enter output value of state A in the unit selected in b).
d)
Enter threshold value when state changes from A to B.
e)
Enter delay time when state changes from A to B.
f)
Enter output value of state B in the unit selected in b).
g)
Enter threshold value when state changes from B to A.
h)
Enter delay time when state changes from B to A.
i)
Enter time when the hysteresis function is activated after vehicle’s startup.
j)
Enter the channel’s state (A or B) at startup.
