Identifying the failure point from the Alarm Summary
Overview
From Experion Release 430 onwards, the Description column of the SCM, RCM, or CR
Fail Alarm displays the description of the failed step output, transition condition, or Phase
instead of the description of the SCM, RCM, or CR. This helps you to directly identify the
failed point without having to search through the SCM/RCM/CR. In addition, this
information is captured in the Experion event journal which can be retrieved at a later point
for reporting and diagnostic purposes.
Additional information about the Description column
The format of the text in the Description column varies depending upon where the SCM,
RCM, or CR failed. The following table illustrates the format of the text in the Description
column based on the failure point.
Failed point Text format in the Description column
Step output Step description, Output description

Text format in the Alarm Summary Description column
For the Fail Alarm to display the description of the failure point, the description of the
following blocks must be configured appropriately:

The alarm description will be blank or incomplete if the block descriptions have not been
configured appropriately.
The following figure displays a sample Alarm Summary and a portion of the configuration
form of the Main tab and the Out #1 tab of the Step block.
