Function
ON when an error occurs in a data transfer in the SYS-
MAC BUS system. The number of the Master involved
is indicated with bits A40500 and A40501.
1: Error
0: No error
The CPU Unit will continue operating and the
ERR/ALM indicator on the front of the CPU Unit will
flash. (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).
1: Error
0: No error
The CPU Unit will continue operating 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 indicated 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).
1: Error
0: No error
The CPU Unit will continue operating 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 indicated in A417.
(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 the Inner Board (including an error
in the Inner Board itself).
1: Error
0: No error
The CPU Unit will continue operating and the
ERR/ALM indicator on the front of the CPU Unit will
flash. The Inner Board will stop operating and details
on the error will be written to A424.
(This flag will be turned OFF when the error is
cleared.)
ON when a Basic I/O Unit registered in the I/O Table
does not match the Basic I/O Unit actually installed in
the PLC because a Unit was added or removed.
1: Mismatch
0: No mismatch
The CPU Unit will continue operating and the
ERR/ALM indicator on the front of the CPU Unit will
flash.
(This flag will be turned OFF when the error is
cleared.)
ON when there is a setting error in the PLC Setup. The
CPU Unit will continue operating and the ERR/ALM
indicator on the front of the CPU Unit will flash. The
location of the error will be written to A406.
1: Error
0: No error
(This flag will be turned OFF when the error is
cleared.)
