Please note
With incorrect installation and high baud rates, data trans
mission faults may occur as a result of signal reflection and
attenuation. Causes of transmission faults may 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 the manual for
your controller for information on the type of cable to be
used.
Use a twisted, screened 5−wire cable for the field bus. The
bus interface is supplied with power via the field bus cable.
Alternatively, you can use bus cables of other manufacturers
(see also Appendix A.2, Accessories).
Please note
If the CPX 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 also the relevant
regulations in EN 60204 part 1.
