Function
When an error has occurred in a Basic I/O Unit (includ-
ing C200H Group-2 High-density I/O Units and C200H
Interrupt Input Units), A40212 will be turned ON and
the slot number where the error occurred will be writ-
ten here in binary.
The CPU Unit will continue operating and the
ERR/ALM indicator on the front of the CPU Unit will
flash.
00 to 09 hexadecimal (Slots 0 to 9)
(These bits will be cleared when the error is cleared.)
When an error has occurred in a Basic I/O Unit (includ-
ing C200H Group-2 High-density I/O Units and C200H
Interrupt Input Units), 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 operating and the
ERR/ALM indicator on the front of the CPU Unit will
flash.
00 to 07 hexadecimal (Racks 0 to 7)
(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 over-
lapping word allocations or a Rack's starting address
exceeds CIO 0901. Bits 00 to 07 correspond to Racks
0 to 7.
1: The same word is allocated on more than one Rack
or the starting word address on the Rack is too high
(i.e., causes the area to be exceeded).
0: No error
(The corresponding flag will be cleared when the error
is cleared.)
The Duplication Error Flag (A40113) and the corre-
sponding flag in A410 will be turned ON when an CPU
Bus Unit's unit number has been duplicated. Bits 00 to
15 correspond to unit numbers 0 to F.
CPU Unit operation will stop and the ERR/ALM indica-
tor on the front of the CPU Unit will light.
1: Duplication detected
0: No duplication
The Duplication Error Flag (A40113) and the corre-
sponding flag in A411 through A416 will be turned ON
when a Special I/O Unit's unit number has been dupli-
cated.
Bits 00 to 15 correspond to unit numbers 0 to F.
(Bits A41100 to A41615 correspond to unit numbers
000 to 05F (0 to 95).)
CPU Unit operation will stop and the ERR/ALM indica-
tor on the front of the CPU Unit will light.
The corresponding bit will also be turned ON when the
Special I/O Unit's words are also allocated to a Basic
I/O Unit on an Expansion I/O Rack because of the
Expansion I/O Rack's starting word setting.
1: Duplication detected
0: No duplication
When an error occurs in a data exchange between the
CPU Unit and an CPU Bus Unit, the CPU Bus Unit
Error Flag (A40207) 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.
1: Error
0: No error
The CPU Unit will continue operating and the
ERR/ALM indicator on the front of the CPU Unit will
flash.
