Connecting the field bus

1.3.1 Field bus cable

1-16
Please note
With incorrect installation and high baud rates, data trans-
mission errors may occur as a result of signal reflexions
and attenuations.
Causes of the transmission errors may be:
– missing or incorrect terminating resistor
– incorrect screening connection
– branches
– transmission over long distances
– unsuitable cables.
Observe the cable specifications. Refer to the manual for
your controller for information on the cable type.
Use a twisted, screened 4-wire cable for the field bus. The
bus interface and the internal logics of the CPV valve terminal
are supplied with power via the field bus cable.
If the Festo IP65 plug is used, cables with a diameter of 5...8
or 7...10 mm are permitted.
Please note
If the valve terminal is fitted onto the moving part of a ma-
chine, the field bus cable on the moving part must be pro-
vided with strain relief. Please observe the relevant regula-
tions in EN 60204 part 1.
