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.
