CS/CJ CPU Bus Unit Duplication Error Flag
Bit A40113 is turned ON when two 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.
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.
Error Information: CIO 1500 + 25 × (Unit No.) (See page 304.)
