Address
A41100 to
The Duplication Error Flag (A40113) and the corresponding
A41615
flag in A411 through A416 will be turned ON when a Special
I/O Unit's unit number has been duplicated. (Bits A41100 to
A41615 correspond to unit numbers 0 to 95.)
A40202
ON when an installed Special I/O Unit does not match the
Special I/O Unit registered in the I/O table.
A42800 to
When a Special I/O Unit Setting Error occurs, A40202 and
A43315
the corresponding flag in these words are turned ON. (Bits
A42800 to A43315 correspond to unit numbers 0 to 95.)
A40206
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).
A41800 to
When an error occurs in a data exchange between the CPU
A42315
Unit and a Special I/O Unit, the Special I/O Unit Error Flag
(A40206) and the corresponding flag in these words are
turned ON.
If the PLC Setup is set to turn ON the corresponding Error
Unit Number Flag when a Special Unit (Special I/O Unit or
CPU Bus Unit) is being replaced, the corresponding flag will
be turned ON when the Unit is being replaced.
Address
A40208
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).
A42400 to
When an error occurs in a data exchange between the CPU
A42415
Unit and the Inner Board, the Inner Board Error Flag
(A40208) and the appropriate error code will be written to
A424.
A40112
ON when there is an Inner Board Error (watchdog timer
error).
With a Single CPU System, CPU Unit operation will stop.
With a Duplex CPU System in Duplex Mode, operation will
switch to the standby CPU Unit and operation will continue.
With a Duplex CPU System in Simplex Mode, CPU Unit
operation will stop.
A32406
ON when an Inner Board Error has occurred in the Inner
Board in the CPU Unit on the right. A40208 will also turn
ON.
A32407
ON when an Inner Board Error has occurred in the Inner
Board in the CPU Unit on the left. A40208 will also turn ON.
