A405.08 The Units that are connected do not
agree with the registered I/O tables
or the number of Units that are con-
nected does not agree with the num-
ber in the registered I/O table.

• If the number of Units is not correct, turn OFF the
power supply and correctly connect the proper
Units.
• With the CJ2 CPU Unit, if the I/O verification oper-
ation
*1
is performed when the number of Units is
incorrect, mismatch errors will be detected for all
Units registered in the I/O tables. If this occurs
even when the number of Units is correct, it is
possible that a Unit has failed and is not being
correctly recognized. Generate new I/O tables,
and then read the I/O tables and check for Units
that are not being recognized.
• If the number of Units is correct, confirm the Unit
in discrepancy, turn OFF the power supply, and
then correct the Unit connections.
• If there is a mistake in the I/O tables, generate
new I/O tables or edit the tables to correct the mis-
take.
An Interrupt Input Unit has been
mounted in the wrong slot, i.e., not in
one of the following slots on the CPU
Rack, or has been registered in the
registered I/O tables in any slots
other than the following slots.
• CJ2H-CPU6@-EIP: CPU Rack
slots 0 to 3
• CJ2H-CPU6@ or CJ2M-CPU3@:
Slots 0 to 4 in CPU Rack
• When an Interrupt Input Unit is used, A405.08 will
turn ON if the Interrupt Input Unit is in the wrong
position or is registered in the wrong position.
• If the Unit is connected in a slot on the CPU Rack
that is not in the specified range, move the Unit to
one of the specified CPU Rack slots.
• If the Unit is mounted in a slot on the CPU Rack
that is not in the specified range, correct the I/O
tables so that the Interrupt Input Unit is correctly
registered to one of the specified slots.
Registered I/O tables for the CJ2H-
CPU6@-EIP or CJ2M-CPU3@ were
downloaded to the CJ2M-CPU6ņ or
CJ2M-CPU1@. Or, registered I/O
tables for the CJ2H-CPU6@ or
CJ2M-CPU1@ were downloaded to
the CJ2M-CPU6@-EIP or CJ2M-
CPU3@.
Delete or correct the I/O tables using the CX-Pro-
grammer.

1, 2
One of the following values exceeds
the maximum or is allocated to more
than one Unit.
1. The total number of I/O points
set in the I/O tables exceeds the
maximum allowed for the CPU
Unit (bits: 000)
2. There are more than 32 interrupt
inputs (bits: 001).
3. Three or more Pulse I/O Mod-
ules were connected to a CJ2M
CPU Unit (bits: 100).
4. The number of Expansion Racks
exceeds the maximum (bits:
101).
5. More than 10 I/O Units are con-
nected to one Rack (bits: 111).

Correct the problem and then turn the power supply
OFF and back ON.
