Configure an instrument failure re-alarm for a multistate point

Multistate records do not have a state dedicated to an instrument fail condition, and as such, they require additional configuration to have one of the existing states configured to be reported as an instrument fail state. The following example procedure details how to configure an Instrument Failure re-alarm for a multistate point.

Note: In this example, the TRANSIT state is associated with Instrument Failure state in a multistate point.

To configure an Instrument Failure re-alarm for a multistate point

1. From the Advanced Database Editor (ADE), do one of the following:

   • Select the plus icon (+) to expand the message table, and double-click the desired message record.

   • Double-click the table row to open the message Table Edit dialog box to create a new record.

     The message Table Edit dialog box appears.

     

2. In the State Name field of the desired message record, change TRANSIT to INSTR FAIL, which also satisfies the regular expression (RegEx) match string in the RealTime registry setting.

   Note: If the instrument failure condition is configured as an attribute (INSTR_FAIL_AS_ATTRIBUTE set to true), the RegEx is not used. For the internationalization process, see the procedures outlined in Configure msginfo sets.

3. In the State Severity field of the desired message record, select (...), and select either critical or high.

4. Select Save, and close.

5. From ADE, do one of the following:

   • Select the plus icon (+) to expand the multistate table, and double-click the desired multistate record.

   • Double-click the table row to open the multistate Table Edit dialog box to create a new record.

     The multistate Row Edit dialog box appears.

     

6. Select the Input tab.

   The Input tab appears.

   

7. In the Instrument Failure State field, select (...), and select INSTR FAIL.

8. Select the Alarming tab.

   The Alarming tab appears.

   

9. Select Sustain COS Alarms.

10. In the Enable Realarm (0-255 mins) field, enter 1.

    If this multistate point is in an INSTR FAIL alarm state, after acknowledging this alarm, it will re-alarm in about 1 to 2 minutes.
