An Expansion I/O Rack's starting
word address exceeds CIO 0901.
The corresponding bit in A40900 to
A40907 (Racks 0 to 7) will be
turned ON.
80E1 A407: Too The probable causes are listed
Many I/O below. The 3-digit binary value (000
Points, to 101) in A40713 to A40715 indi-
Details cates the cause of the error. The
value of these 3 bits is also output
to A40700 to A40712.
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. The number of Expansion
Racks exceeds the maximum
(bits: 101).
80E0 --- Input and output word allocations
do no agree with input/output words
required by Units actually mounted.
Probable cause
Try turning the power OFF and ON
again.
If the error isn't corrected, turn the
power OFF and check cable connec-
tions between the I/O Units and
Racks.
Check for damage to the cable or
Units.
Correct the cause of the error and
then turn the Rack's power supply
OFF and then ON again.
Turn OFF the power supply and
replace the Backplane with a CS1D-
B@@@@ Backplane.
Correct the cable connections.
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 in ON in A40900 to
A40907. 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 A40900 to A40907
and change the setting to a valid word
address below CIO 0901 with a Pro-
gramming Device.
Correct the problem indicated by the
content of A407 and turn the power
OFF and ON again.
Check the I/O table with I/O Table Ver-
ification operation. When the system
has been corrected, register the I/O
table again.
