3.8 Bus termination with terminating resistors
Note
If the SFC−LACI is at the start or end of the field bus
segment, a bus terminator is required.
· Fit a bus termination to both ends of a bus segment.
Recommendation:
Use the ready−to−use field bus plugs from Festo for the bus
termination. A suitable resistor network is incorporated in the
housing of this plug (see Fig. 3/5).
