Alarm on Error

This attribute determines whether an entity will produce an alarm when a UCO-related error occurs. They include:

• Expression errors

  Note that, if the quality on an expression is bad and the Resume on Error check box is selected, an alarm will not be produced.

• Client session errors

• Utilization event errors

• Entity naming errors

• OEE and utilization value errors

If the Alarm on Error attribute is selected, then the following attributes become available.

Alarm Priority

A number that is logged and that represents the priority of the System Platform alarm.

Alarm Message

The System Platform alarm message that is logged.

You can manually enter the alarm message, or click the Browse button to select and insert a System Platform attribute reference into the alarm message.

Two types of alarm conditions are available for equipment monitoring:

• An alarm indicating that an error occurred while attempting to determine the current raw reason code. For example, an attribute reference contained in an expression for a raw reason code goes to bad quality.

• You can monitor the current raw reason code and use scripting in conjunction with alarm extensions to trigger an alarm. For instance, a field attribute of type Boolean can be added to the UCO and an alarm extension set on it. Then, a script can be written to set this attribute if a specific raw reason code or set of raw reason codes is detected on the object.
