Please note
Fit a bus termination at both ends of the bus segment. This
also applies when the module or the interface is at the
beginning of a bus cable.
If the CPV valve terminal is at the end of the field bus system,
a bus termination will be required.
If you are using T-adapters, we recommend that you install
the terminating resistor at the unused output of the T-
adapter.
Recommendation:
Fit a resistor (120 Ω, 0.25 W for the bus termination in the
sub-D plug from Festo, see Fig. 1/19).
