Bus termination
The bus segment must be terminated on both ends of the line. According to the
FISCO model the termination must conform to the following limits:
•90 Ohm <
R < 100 Ohm
•0 µF <
C < 2,2 µF
Figure 26. Bus termination according to FISCO
A fieldbus terminator is integrated into the Power Link Module PL 890 so that an
external bus termination is only required on the other end of the bus.
