Short description
The increasing use of computers and related equipment in Direct Numericai Control (DNCI) Systems for storage and distribution of machine programs to numerically controlled machines and for communication between various components of DNC systems has demonstrated the need for a standard data communication link between the DNC and the numerical control unit. As a result, the EIA Committee IE-31 which is made up of representatives of numerical control system builders, machine builders and users has prepared this standard for use by people specifying, building and using DNC systems.
