Visualisation of automatic sequences - integration with process mimic display

Paper in proceeding, 2010

The paper presents a generic conceptual interface to visualise automatic sequences in process industry applications exemplified by a feed water sub- system. The design is based on operators’ information need during use of automatic sequences. The information need was elicited using interviews with nuclear power, thermal power and pulp and paper plant operators. By integrating process mimics, time line and logical conditions, the observability of automatic sequences was improved. The interface has the potential to enhance operators’ ability to observe automatic system activity, avoid black box automation and thus reduce the possibility of out-of-the-loop effects.
