Description
Retries failed The PLC could not send the data
within the specified number of
retries (possibly caused by
noise).
Controller error Check the status of the Commu-
nications Unit.
Elements/data The number of elements or data
don't match does not match (possibly caused
by noise).
Address range An address specified in the
error screen data is beyond the range
supported by the PLC. Check the
manuals for your PLC and spec-
ify an address within the sup-
ported range.
I/O setting error Correct the I/O tables in the PLC.
Unit number error Check the unit number setting.
Command for- The data does not match the
mat error expected command format (pos-
sibly caused by noise).
Address range The end address (specified
exceeded address plus number of
accessed words) in the screen

allocations in the screen data.
Too many I/O There are too many I/O points
points registered in the PLC. Correct
the settings in the PLC.
Response time- The response waiting time at the
out PLC expired (possibly caused by
noise).
Header error There is an error in the communi-
cations header information at the
PLC (possibly caused by noise).
CPU bus error Check the connection between
the CPU Unit and CPU Bus Unit
in the PLC and then cycle the
power supply.
I/O duplication Correct the I/O Unit settings in
the PLC.
I/O bus error Check the status of the I/O Units
in the PLC.
Necessary items There is an error in the communi-
not set cations data at the PLC (possibly
caused by noise).
CPU Bus Unit Check the status of the CPU Bus
error Units in the PLC.
Response too The response at the PLC is
long longer than the maximum per-
