Publication date January 1998

During the next few years the main focus of IEC 1131-3 standardisation work is clearly going to concern language concepts and extensions for building distributed applications. Recent developments in the use of distributable software components and concepts such as re-usable software as function blocks are likely to have a major impact in this area. The IEC and the international standardisation bodies have done a great deal of work to create standards in this area. In the long term, the unification of software languages and architectures for distributed industrial control applications will bring major economic advantages to end-users and system builders alike.
