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
branches
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.
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.
