Function
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).
The CPU Unit will continue operat-
ing 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 writ-
ten 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.
The CPU Unit will continue operat-
ing 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.
(This flag will be turned OFF when
the error is cleared.)
ON when an error has occurred in a
Basic I/O Unit
The CPU Unit will continue operat-
ing and the ERR/ALM indicator on
the front of the CPU Unit will flash.
The location of the error will be writ-
ten to A408.
(This flag will be turned OFF when
the error is cleared.)
ON when the Detect Interrupt Task
Errors setting in the PLC Setup is
set to "Detect" and an interrupt task
is executed for more than 10 ms dur-
ing I/O refreshing of a C200H Spe-
cial I/O Unit or a SYSMAC BUS I/O
Unit.
This flag will also be turned ON if an
attempt is made to refresh a Special
I/O Unit's I/O from an interrupt task
with IORF(097) while the Unit's I/O
is being refreshed by cyclic I/O
refreshing (duplicate refreshing).
The CPU Unit will continue operat-
ing 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.)
One of the following errors occurred:
Duplex verification error (see note),
duplex bus error (see note), duplex
Power Supply Unit error, or duplex
communications error
Note: Duplex CPU Systems only.
