Function
The 3-digit binary value of these bits
indicates the cause of the Too Many
I/O Points Error.
(These bits will be cleared when the
error is cleared.)
The Duplication Error Flag (A401.13)
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.
The Duplication Error Flag (A401.13)
and the corresponding flag in A411
through A416 will be turned ON
when a Special I/O Unit's unit num-
ber has been duplicated.
Bits A411.00 to A416.15 correspond
to unit numbers 000 to 05F (0 to 95).
CPU Unit operation will stop and the
ERR/ALM indicator on the front of
the CPU Unit will light.
When an error occurs in a data
exchange between the CPU Unit and
an CPU Bus Unit, the CPU Bus Unit
Error Flag (A402.07) is turned ON
and the bit in A417 corresponding to
the unit number of the Unit where the
error occurred is turned ON. Bits 00
to 15 correspond to unit numbers 0
to F.
The CPU Unit will continue operating
and the ERR/ALM indicator on the
front of the CPU Unit will flash.
When an error occurs in a data
exchange between the CPU Unit and
a Special I/O Unit, the Special I/O
Unit Error Flag (A402.06) will be
turned ON.
Each bit corresponds to a unit num-
ber. Bits A418.00 to A423.15 corre-
spond to unit numbers 000 to 05F (0
to 95).
The CPU Unit will continue operating
and the ERR/ALM indicator on the
front of the CPU Unit will flash.
The unit number of the Unit where
the error occurred is indicated in
A417.
If the unit number of the Unit is
uncertain, none of the flags will be
turned ON.
(The flag will be turned OFF when
the error is cleared.)
The bit corresponding to the option
slot turns ON when an error occurs
in an Option Board (A315.13 will be
ON).
