Problems with electromagnetic
compatibility (EMC)
EEPROM check sum error
Inline code buffer overflow.
Too many entries in the table
Set manufacturer’s setting with
the KS2000
Check power supply for under-
or overvoltages
Implement EMC measures
If there is a K bus error, the
error can be localised by
restarting the field bus coupler
(switching it off and on again)
Insert fewer terminals

Terminal bus command error
No terminal inserted, connect

A terminal is faulty
Disconnect half the terminals
and check whether the error
recurs. Continue this process
until the faulty terminal is
located

K bus runtime command error One bus terminal faulty. Halve
the number of bus terminals
and check the remaining bus
terminals for errors. Repeat this
process until the faulty bus
terminal is localised.
