8.1 Baud rate detection
Figure 60: Baud rate detection
With the function Baud rate detection the current baud rate on
the running PROFIBUS is displayed. During the baud rate scan
additionally the all over signal level on the PROFIBUS is
measured and evaluated.
U < 2.5 V: Weak level or no longer detectable.
2.5 - 7.2 V: Level is ok.
U > 7.2 V: If the indicated level is > 7.2 Volt, this is an
indication for a faulty power supply of the
Slaves or for reflections at the bus.
