I have a fieldbus system (controller & field devices) of manufacturer 'A'. What are the things I need to obtain from other field devices manufacturers 'B', 'C' or 'D' if I need to replace the field devices 'A'?
As I understand, even when all fieldbus manufacturers are registered under the Foundation Fieldbus (FF)group, the field devices are not interchangeable (unlike the 4-20ma/ Hart).
