Interface error
Error
Possible error cause
Measures
No communication
via the Ethernet in-
terface
• Incorrect wiring
• Different protocol settings
• Protocol not released
• Check wiring
• Check protocol settings
• Activate TCP/IP or UDP
Sporadic errors at
the Ethernet inter-
face
• Incorrect wiring
• Effects due to EMC
• Overall network expansion ex-
ceeded
• 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 connec-
tion 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. cable lengths
