A Cause & Effects (C&E) Diagram 1) identifies the instrument loops and connections with the process items that is to prevent accidents and help in the design of controls and protective systems for a process plant. The Cause and Effect is presented as a form of matrix in which the Cause means something happen, and Effect is what happens as a result of the cause. A C&E Diagram is a deliverable of the Detailed Design and Engineering developed by CSI and Process disciplines; 2) A C&E Diagram is a brainstorming tool in the shape of a fishbone showing all possible variables that affect a specific process output.
Reference Definition by InstrumentationPotal.com: A Cause and Effect (C&E) Diagram is presented as a form of matrix. The causes are listed in left section while the effects are listed on top section, both are described in form of tag number with their descriptions (other additional information such as P&ID may supplement). The marked intersection between both means that they are related as cause-effect. Marks could be in form of letter “X” which mean effect will be activated, “T” which mean effect will be activated with time delay, “P” which mean cause will give permissive to an effect. There are two categories of Cause and Effect Diagram: ESD C&E Diagram and Fire and Gas C&E Diagram.
