Function
ON when program contents are incor-
rect. CPU Unit operation will stop and
the ERR/ALM indicator on the front of
the CPU Unit will light. The task num-
ber where the error occurred will be
stored in A294 and the program
address will be stored in A298 and
A299. The type of program error that
occurred will be stored in A295.08 to
A295.15. Refer to the description of
A295 for more details on program
errors.
ON when the number of Expansion
Units and Expansion I/O Units exceeds
the limit, when the number of words
allocated to these Units exceeds the
limit, are mounted.
CPU Unit operation will stop and the
ERR/ALM indicator on the front of the
CPU Unit will light.
ON in the following cases:
• When an error occurs in a data
transfer between the CPU Unit and a
Expansion Unit or Expansion I/O
Unit. If this happens, 0A0A 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.
ON when an error occurred in memory.
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 automatic 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.
ON when a non-fatal error that is not
defined for A402.01 to A402.15 occurs.
Detailed information is output to the
bits of A315.
ON if the CPU Unit's battery is discon-
nected 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.
