A407.13 to One of the following values exceeds
A407.15: Too the maximum or is allocated to more
Many I/O than one Unit.
Points, Details
1. The total number of I/O points
1, 2
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. The number of Expansion Racks
exceeds the maximum (bits:
101).
4. More than 10 I/O Units are con-
nected to one Rack (bits: 111).

Rack Number
An Expansion Rack's starting word
address exceeds CIO 0901.The cor-
responding bit in A409.00 to A409.03
(Racks 0 to 3) will be turned ON.
Probable cause
Correct the problem and then turn the power supply
OFF and back ON.
*4
Check the unit numbers, eliminate the duplications,
and turn the Rack's power supply OFF and then ON
again.
Check the unit numbers, eliminate the duplications,
and turn the Rack's power supply OFF and then ON
again.
Check allocations to Units on the rack number
whose bit is ON in A409.00 to A409.03. Correct the
allocations so that no words are allocated more than
once, including to Units on other Racks, and turn the
Rack's power supply OFF and then ON again.
Check the first word setting for the Rack indicated in
A409.00 to A409.03 and change the setting to a
valid word address below CIO 0900 with a Program-
ming Device (such as a CX-Programmer).
