Auxiliary Area Allocations
Error Codes and Error Flags
Classification
System-defined fatal errors
User-defined fatal errors
User-defined non-fatal errors
System-defined non-fatal errors 009A
Note 1. Operation will be switched to the standby CPU Unit in Duplex CPU Systems.
2. C101 to C2FF will be stored for FALS numbers 001 to 511.
3. 4101 to 42FF will be stored for FAL numbers 001 to 511.
4. The contents of the error flags for a duplicate number error are as follows: Bits 0 to 7: Unit number
(binary), 00 to 5F hex for Special I/O Units, 00 to 0F hex for CPU Bus Units,
Bits 8 to 14: All zeros, Bit 15: Unit type, 0 for CPU Bus Units and 1 for Special I/O Units.
5. Only the contents of A295 is stored as the error flag contents for program errors.
6. 0000 hex will be stored as the error flag contents.
7. The rightmost digit of the error code (0 to F) for duplex communications error corresponds to CPU
Bus Unit unit numbers 0 to F.
8. These error occur only for Duplex CPU Systems.
9. These error occur only for Single CPU Systems or Process-control CPU Units.
