President of UCDS Ian Nimmo explains abnormal situation management. From a production perspective, how do we keep processes within normal operating limits? Abnormal situation management is when a process begins to function outside those limits, and an operator must step in to help the automation system. Today, HMI tools are needed to give operators indication that the process is off normal. Your operator needs to be able to recognize when things are off normal, the time difference between off normal and abnormal, and when abnormal changes to an emergency situation. One of our tools is Situation Awareness, which assists the operator in detecting, diagnosing, and responding to abnormal situations.
