The 2 possible causes of the Too Many I/O Points Error are
listed below. The 3-digit binary value in A40713 to A40715
indicates the cause of the error. (The causes corresponding
to values 0 to 5 are listed below.)
• The number of I/O points will be written here when the
• The number of Racks will be written here when the num-
• Number of interrupt input points when there are more than
These three bits indicate the cause of the Too Many I/O
Points Error. (See A40700 to A40712.)
000 (0): Too many I/O points
001: Too many interrupt input points
101 (5): Too many Expansion Racks connected
ON when an error occurs in a data transfer between the
CPU Unit and a Unit mounted to a slot.
Contains the 8-bit binary slot number (00 to 08) where an
I/O Bus Error occurred in binary (00 to 08 hex).
Contains the 8-bit binary rack number (00 to 07) where an
I/O Bus Error occurred in binary (00 to 07 hex).
ON in the following cases:
Two CPU Bus Units have been assigned the same unit num-
ber.
Two Special I/O Units have been assigned the same unit
number.
Two Basic I/O Units have been allocated the same words.
The same rack number is set for more than one Expansion
Rack.
Refer to information provided separately in this manual on
I/O table creation.
The Duplication Error Flag (A40113) and the corresponding
flag in A410 will be turned ON when a CPU Bus Unit’s unit
number has been duplicated.
Bits 00 to 15 correspond to unit numbers 0 to F.
When an error occurs in a data exchange between the CPU
Unit and a CPU Bus Unit, the CPU Bus Unit Error Flag
(A40207) and the corresponding flag in A417 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.
If a duplexed CLK Unit is being replaced, the corresponding
flag will be turned ON during replacement.
Bits 00 to 15 correspond to unit numbers 0 to F.
When a CPU Bus Unit Setting Error occurs, A40203 and the
corresponding flag in A27 are turned ON.
Bits 00 to 15 correspond to unit numbers 0 to F.
ON when an installed CPU Bus Unit does not match the
CPU Bus Unit registered in the I/O table.
ON when an error occurs in a data exchange between the
CPU Unit and a CPU Bus Unit (including an error in the CPU
Bus Unit itself).
total number of I/O points set in the I/O Table exceeds the
maximum allowed for the CPU Unit.
ber of Expansion I/O Racks exceeds the maximum.
