The process control industry is highly competitive. Most systems have
similar features. However, a major factor to consider in the selection
process is the user interface. This is where the user, operator, engi
neer, production control engineer, scheduler, etc., obtains the inform
ation he/she needs to effectively operate the plant in a safe and effi
cient manner. In discussing the scope of the user interface, three maj
or areas will be reviewed: the functional areas of the production proc
ess and how the user interface fits into that domain in terms of funct
ional scope, the user trends in terms of emerging operational trends a
nd their impact on functional requirements, and the user interface con
cepts including control room operations, control room layout, non-cont
rol room operations, and solution management.
