Bus termination with terminating resistors

Note
If the SFC−LACI is at the start or end of the fieldbus segĆ
ment, a bus terminator is required.

·

Always use a bus termination at both ends of the fieldĆ
bus.

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 fieldĆ
bus plug for the bus termination.

Bus termination with resistor in fieldbus plug FBS−SUB−9−BU−2x5POL−B

Fieldbus 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 fieldĆ
bus, you must install a terminating resistor (120

Ω, 0.25 W) in

the fieldbus socket:

·

Connect the terminating resistor between the cores for
CAN_H and CAN_L.
