is not detected
• Check connection cable
• Install USB driver
Sporadic errors at the
Ethernet interface
• Incorrect wiring
• Effects due to EMC
• Overall network expansion exceeded
• Check wiring:
- In particular, check wire shielding
- Check the cable used
• Check shielding (shield covering in place up to the
clamping point)
• Check grounding concept and connection to functional
earth (FE)
• Avoid EMC coupling caused by power cables laid parallel
to device lines
• Check max. network expansion as a function of the max.
