Function
When there is a setting error in the
PLC Setup, the location of that error
is written to A406 in 4-digit hexadec-
imal. The location is given as the
address displayed on a Program-
ming Console.
The CPU Unit will continue operat-
ing and the ERR/ALM indicator on
the front of the CPU Unit will flash.
(A406 will be cleared when the
cause of the error is eliminated.)
When there are too many I/O, CPU
Unit operation will stop, the ERR/
ALM indicator on the front of the
CPU Unit will light, and one of the
following values will be stored here.
The total number of I/O points will be
written here if the capacity of the
CPU Unit is exceeded.
The number of Racks will be written
here when the number of Expansion
I/O Racks exceeds the maximum.
Number of interrupt input points
when there are more than 32 (Single
CPU Systems only)
(These bits will be cleared when the
error is cleared.)
The 3-digit binary value of these bits
indicates the cause of the Too Many
I/O Points Error and shows the
meaning of the value written to bits
A40700 to A40712.
(These bits will be cleared when the
error is cleared.)
When an error has occurred in a
Basic I/O Unit, A40212 will be
turned ON and the slot number
where the error occurred will be writ-
ten here in binary.
(These bits will be cleared when the
error is cleared.)
When an error has occurred in a
Basic I/O Unit, A40212 will be
turned ON and the Rack number
where the error occurred will be writ-
ten here in binary.
The CPU Unit will continue operat-
ing and the ERR/ALM indicator on
the front of the CPU Unit will flash.
(These bits will be cleared when the
error is cleared.)
The corresponding flag will be
turned ON when an Expansion I/O
Rack's starting word address was
set from a Programming Device and
two Racks have overlapping word
allocations or a Rack's starting
address exceeds CIO 0901. Bits 00
to 07 correspond to Racks 0 to 7.
(The corresponding flag will be
cleared when the error is cleared.)
The Duplication Error Flag (A40113)
and the corresponding flag in A410
will be turned ON when an CPU Bus
Unit's unit number has been dupli-
cated. Bits 00 to 15 correspond to
unit numbers 0 to F.
CPU Unit operation will stop and the
ERR/ALM indicator on the front of
the CPU Unit will light.
