These Boolean attributes are used to enable (1) or disable (0) the S-Device Super-
visor object’s process of setting Exception bits. When disabled, corresponding bits
are never set; and, if they were set, disabling clears them. Also, alarm and warning
states are not retained; when enabled, bits will be set only if the corresponding
condition is true.
The default state for these Enable attributes is enabled (1).
