Why is termination important?

Termination prevents reflections that can disturb the data communication. The higher the baudrate and the longer the cable, the more important termination becomes. Termination should be activated/placed at both ends of every bus segment. With PROFIBUS DP the termination is powered to provide an idle level when nobody is sending data. With PROFIBUS PA the termination is a combination of a resistor and a capacitor.
