CS/CJ CPU Bus Unit Duplication Error Flag
Bit A40113 is turned ON when t
wo CS/CJ CPU Bus Units have been assigned the same unit number. The dupli-
cated unit number is indicated in A410.
CS/CJ CPU Bus Unit Error, Unit Number Flags
When an error occurs in a data exchange between the CPU Unit and an CS/CJ CPU Bus Unit, the CS/CJ 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.
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.
CS/CJ CPU Bus Unit Restart Bits
Bits A50100 through A50115 can be turned ON to reset CS/CJ CPU Bus Units number #0 through #15,
respectively. The Restart Bits are turned OFF automatically when restarting is completed.

CIO Area: CS/CJ CPU Bus Unit Area
The CS/CJ CPU Bus Unit Area (CIO Area) is allocated to CS/CJ CPU Bus Units according to the unit numbers
assigned to them, as shown below. Each Unit is allocated 25 words.
