Diagnostics and troubleshooting
Measures
• Check supply voltage
• Send device to customer service
• Query diagnostic data and carry out the
resulting measures
• Internal device error, send in device
• Reset service mode with webConfig tool
or display
• Check supply voltage
• Send device to customer service
• Check interface
• Check interface
Measures
• Check interconnection cable
• Install USB driver
• Check wiring
• Check protocol settings
• Activate TCP/ IP or UDP
• 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 func-
tion of the max. cable lengths
