Voting (Alarm Logic)
Field type: Integer
The value entered in this field applies to the configuration conditions described above. Optio-
nal status combinations (alarm, fail, and inhibit) can be formed when the selected relay output
is configured. The number value selected in this field determines how many of the conditions
configured in the control boxes must be met for the selected relay output to be activated. The
number of conditions entered in the check boxes is displayed in the field beside the voting to
be configured.
The following types of links can be formed in this manner:
