3.3 Terminating resistor on the last fieldbus slave
If the valve terminal is at the end of the fieldbus system, a
cable termination is required.
Recommendation:
Use the Sub−D plug from Festo. A suitable RC network has
already been fitted into the housing of the Festo Sub−D
plug. The cable termination must be switched manually
(see Electronics manual").
