The last year’s discussions on communication between field
instrumentation have very much focused on standardized field buses
as FieldBus, ProfiBus and others. In many instrumentation processes they are a powerful tool to have good control over an industrial process and can in many cases be the best economical alternative too. There was also a belief that these busses would solve all interface and connection problems between different types of manufacturer specific instruments i.e. anything could be connected without any problems.
