status LED continuous
red light
• Incorrect wiring
• Different protocol settings
• Protocol not released
• Wrong termination
• Incorrect device name set
• Incorrect configuration
• Check wiring
• Check protocol settings
• Activate TCP/ IP or UDP
• Check termination
• Check device name
• Check configuration of the device in the configuration tool
Sporadic errors at the
PROFINET-IO
• 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 clamp-
ing 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.
cable lengths
