Alarm Analyst - Correlation analysis
Correlation Analysis;-Easy to build Knowledge-Base alarm & event
model… unique technology
From alarm & event historical logs, Correlation Analysis extracts ;- Event groups consisted of the alarms and the operation
actions in a process upset Propagation path Source origin Nuisance alarms Total counts in Alarm & Event group Information about Alarm & Event group structure Cause & Effect relationship
– Cause of alarm flood or complex operation is estimated using order of events occurrence.

SVP3000: High durability and stability
Isolated design between electronics and pneumatic circuits This design eliminates troubles caused by dusty and humid air quality. Instrumentation air and outside atmosphere do not come into the electronics
circuit department.
