An adequate and economic automation of production plants demands standardized and transferable solutions especially as far as computer controlled production is concerned. New developments of hardware and software components offer potential users extendable systems which, depending on the degree of extension, are capable of coping with both the technical and the organizational information flow within the production plant. In course of research developments concerned with the automation of production installation, a DNC-system was. first built using standardized process peripherals (CAMAC) and modular process control software written in a high-level language (PROCESS-FORTRAN) and later implemented in industry.
