MODE
MODE Meaning
00 All newly occurring interrupts and asynchronous errors are disabled. (Synchronous errors
are not disabled.) Assign the OB_NR parameter the value 0. Entries continue to be made in
the
diagnostic buffer.
01 All newly occurring events belonging to a specified interrupt class are disabled. Identify the
interrupt class by specifying it as follows:
Time- of-day interrupts: 10
Time-delay interrupts: 20
Cyclic interrupts: 30
Hardware interrupts: 40
Interrupts for DPV1: 50
Multicomputing interrupts: 60
Redundancy error interrupts: 70
Asynchronous error interrupts: 80
Entries into the diagnostic buffer are continued.
02 All new occurrences of a specified interrupt are disabled. You specify the interrupt using the
OB
number. Entries continue to be made in the diagnostic buffer.
80 All newly occurring interrupts and asynchronous errors are disabled and are no longer entered
in the diagnostic buffer. The operating system enters event W#16#5380 in the diagnostic
buffer.
81 All newly occurring belonging to a specified interrupt class are disabled and are no longer
entered in the diagnostic buffer. The operating system enters event W#16#5380 in the
diagnostic buffer.
82 All newly occurring belonging to a specified interrupt are disabled and are no longer entered in
the diagnostic buffer. The operating system enters event W#16#5380 in the diagnostic buffer.
