Connecting to the field bus
1.3.1
Field bus cable
Note
If installation has not been carried out correctly and if high
baud rates are used, data transmission errors may occur
as a result of signal reflections and attenuations.
Causes of the transmission faults can be:
– missing or incorrect terminating resistor
– incorrect screening/shield connection
– branch lines too long
– transmission over long distances
– unsuitable cables.
Observe the cable specifications. Refer to your controller
manual for information on the type of cable to be used.
Use a twisted, screened 4-core cable for connecting the field
bus. The bus interface is supplied with power via the field bus
cable.
If the Festo field bus plug is used, a cable diameter of
5 … 8 mm or 7 … 10 mm is permitted.
Note
If the valve terminal is fitted into a moving part of a
machine, the field bus cable on the moving part must be
provided with strain relief. Note the relevant regulations in:
IEC/DIN EN 60204-1.
