4. The error code and the time/date that the error occurred will be written to
the Error Log Area (A100 through A199).
5. The ERR Indicator on the CPU Unit will flash.
6. The ASCII message in D00100 to D00107 will be displayed at the Periph-

Clearing a Particular Non-fatal Error
When CIO 000001 is ON in the following example, FAL(006) will clear the
non-fatal error with FAL number 31, turn OFF the corresponding Executed
FAL Number Flag (A36114), and turn OFF the FAL Error Flag (A40215).
Clearing All Non-fatal Errors
When CIO 000002 is ON in the following example, FAL(006) will clear all of
the non-fatal errors, turn OFF the Executed FAL Number Flags (A36001 to
A39115), and turn OFF the FAL Error Flag (A40215).
Clearing the Most Serious Non-fatal Error
When CIO 000003 is ON in the following example, FAL(006) will clear the
most serious non-fatal error that has occurred and reset the error code in
A400. If the cleared error was originally generated by FAL(006), the corre-
sponding Executed FAL Number Flag and the FAL Error Flag (A40215) will be
turned OFF.
Generating a Non-fatal System Error (CS1-H, CJ1-H, CJ1M, or CS1D
Only)
When CIO 000000 is ON in the following example, FAL(006) will generate a
CPU Bus Unit Setup Error for unit number 1. In this case, dummy FAL number
10 is used and the corresponding value (000A hex) is stored in A529.
