Error Possible error cause Measures
No communication via
RS 232/RS 485
• Incorrect wiring.
• Different baud rates.
• Different protocol
settings.
❏ Check wiring.
❏ Check baud rate.
❏ Check protocol settings.
Sporadic errors on the
RS 232-/RS 485 inter-
face
• Incorrect wiring.
• Effects due to EMC.
• Overall network expansion
exceeded.
❏ Check wiring, in particular the shield of the
wiring.
❏ Check the cable used.
❏ Check shielding (shield covering in place up
to the clamping point).
❏ Check grounding concept and connection to
PE.
❏ Check max. network expansion as a func-
tion of the max. cable lengths.
