Failure Diagnosis Instructions
Section 3-30
4.
The following table shows how the IOM Hold Bit affects the status of I/O
memory and the status of outputs on Output Units after a fatal system error
has been generated with FALS(007).
Note Unlike user-defined fatal errors, system errors generated by FALS(007) will
clear I/O memory if the IOM Hold Bit is OFF. The following areas will be
cleared: CIO Area, Work Area, Timer Flags and PVs, Index Registers, and
Data registers.
The following table shows how to specify error codes and error details in S
and S+1.
