A document that defines how process conditions initiate alarms, trips and automated control actions within a control or safety system.
A Cause and Effect (C&E) Matrix is an engineering document that specifies the logical relationships between process inputs (causes) and the resulting control system or safety system responses (effects). It defines how alarms, shutdowns, interlocks and other automated actions are triggered when specified operating conditions occur.
The Cause and Effect Matrix provides a clear, auditable definition of control and safety logic, supporting system design, testing, commissioning and ongoing plant operation.
The Cause and Effect Matrix serves as a key reference throughout the lifecycle of control and safety systems and is commonly used during functional testing, loop checking and operator training.
A Cause and Effect Matrix defines operational logic and should not be confused with an Ishikawa (fishbone) cause-and-effect diagram used for Root Cause Analysis.
