Function
ON when an installed Special I/O
Unit does not match the Special I/O
Unit registered in the I/O table. The
CPU Unit will continue operating and
the ERR/ALM indicator on the front
of the CPU Unit will flash.
The unit number of the Unit where
the setting error occurred is indi-
cated in A428 to A433.
(This flag will be turned OFF when
the error is cleared.)
ON when an installed CPU Bus Unit
does not match the CPU Bus Unit
registered in the I/O table. The CPU
Unit will continue operating and the
ERR/ALM indicator on the front of
the CPU Unit will flash.
The unit number of the Unit where
the setting error occurred is written
to A427.
(This flag will be turned OFF when
the error is cleared.)
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.
With a Duplex CPU System, this flag
applies to both the left and right
CPU Unit.
The CPU Unit will continue operat-
ing 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 indi-
cator to indicate that the battery
needs to be replaced.
(This flag will be turned OFF when
the error is cleared.)
ON when an error occurs in a data
exchange between the CPU Unit
and a Special I/O Unit (including an
error in the Special I/O Unit itself).
The CPU Unit will continue operat-
ing and the ERR/ALM indicator on
the front of the CPU Unit will flash.
The Special I/O Unit where the error
occurred will stop operating and the
unit number of the Unit where the
data exchange error occurred is indi-
cated in A418 through A423.
(This flag will be turned OFF when
the error is cleared.)
ON when an error occurs in a data
exchange between the CPU Unit
and an CPU Bus Unit (including an
error in the CPU Bus Unit itself).
The CPU Unit will continue operat-
ing and the ERR/ALM indicator on
the front of the CPU Unit will flash.
The CPU Bus Unit where the error
occurred will stop operating and the
unit number of the Unit where the
data exchange error occurred is indi-
cated in A417.
(This flag will be turned OFF when
the error is cleared.)
