A401
A401.14 I/O Bus Error
Flag
(fatal error)
ON in the following cases:
• When an error occurs in a data
transfer between the CPU Unit
and a CPM1A Expansion Unit or
Expansion I/O Unit. If this hap-
pens, 0A0A hex will be output to
A404.
• When an error occurs in a data
transfer between the CPU Unit
and a CJ-series Unit. If this hap-
pens, 0000 hex will be output to
A404 to indicate the first Unit,
0001 hex to indicate the second
Unit, and 0F0F hex to indicate an
undetermined Unit.
• When the End Cover is not
attached to the last CJ-series Unit.
If this happens, 0E0E hex will be
output to A404.
CPU Unit operation will stop and the
ERR/ALM indicator on the front of
the CPU Unit will light.
(This flag will be turned OFF when
the error is cleared.)

A401.15 Memory Error
Flag
(fatal error)
ON when an error occurred in mem-
ory or there was an error in auto-
matic transfer from the Memory
Cassette when the power was turned
ON.
CPU Unit operation will stop and the
ERR/ALM indicator on the front of
the CPU Unit will light.
The location where the error
occurred is indicated in A403.00 to
A403.08, and A403.09 will be turned
ON if there was an error during auto-
matic transfer at startup.
This flag will be turned OFF when
the error is cleared. (The automatic
transfer at startup error cannot be
cleared without turning OFF the
PLC.)

Error Flag
ON when a non-fatal error that is not
defined for A402.01 to A402.15
occurs. Detailed information is output

A402.04 Battery Error
Flag
(non-fatal
error)
ON if the CPU Unit’s battery is dis-
connected or its voltage is low and
the Detect Battery Error setting has
been set in the PLC Setup.
The CPU Unit will continue operating
and the ERR/ALM indicator on the
front of the CPU Unit will flash.
This flag can be used to control an
external warning light or other indica-
tor to indicate that the battery needs
to be replaced.
(This flag will be turned OFF when
the error is cleared.)
