CPU Bus Unit Number
Duplication Flags
A410.00 to
A410.15
The Duplication Error Flag (A401.13) 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.
Read-only
CPU Bus Unit Error, Unit
Number Flags
A417.00 to
A417.15
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 corre-
sponding 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.
Read-only
