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.
· Always use a bus termination at both ends of the
fieldbus.
If you are using T−adapters, install the terminating resistor at
the unused output of the T−adapter.
Recomme
ndation: Fit a terminating resistor in the Festo field
bus plug for the bus termination.

Fig.3/7: Bus termination with resistor in field bus plug FBS−SUB−9−BU−2x5POL−B
Field bus plug FBS−SUB−9−WS−CO−K (IP20) has an integrated
switchable terminating re
sistor.
Install a terminating resistor using the adapters
If the SFC−LACI you are connecting is at the end of the field
bus, you must install a terminating resistor (120 , 0.25
W) in
the field bus socket:
· Connect the terminating resistor between the cores for
CAN_H and CA N_L.
