Possible error causes
Measures
No communication via USB service interface
• Incorrect interconnection cable
• Connected device is not recognized
• Check interconnection cable
• Install USB driver
No communication via
RS 232 / RS 422/ RS 485
• Incorrect wiring
• Check wiring
• Different baud rates
• Check baud rate
• Different protocol settings
• Check protocol settings
Sporadic errors on the
RS 232 / RS 422 / RS 485 interface
• Incorrect wiring
• Check wiring
• In particular, check wire shielding
• Check the cable used
• Effects due to EMC
• 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
• Overall network expansion exceeded
• Check max. network expansion as a func
