3.1 Abstract

FDT is a component based standard, which is constantly enhanced to new improved versions. Control system environments typically run for 10-15 years in contrast. If hardware and software components in a control system have to be exchanged, a mixture of components designed for different FDT versions may emerge.

This raises the question, how components based on different FDT versions can cooperate. This chapter FDT Version Interoperability Guide goes further into this question and provides solutions.
