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
fieldĂbus.
If you are using T−adapters, install the terminating resistor at
the unused output of the T−adapter.
Recommendation: Fit a terminating resistor in the Festo field
bus plug for the bus termination.

Field bus plug FBS−SUB−9−WS−CO−K (IP20) has an integrated
switchable terminating resistor.
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 ġ, 0.25 W) in
the field bus socket:
· Connect the terminating resistor between the cores for
CAN_H and CAN_L.
