1. A method for producing software modules for field devices for process automation technology, that encapsulate all the data and functions of the corresponding field devices, wherein the software modules serve as device descriptions and have defined interfaces for application programs in process control systems, comprising the steps of: generating syntactically correct standard device descriptions from PDM (Process Device Manager) device descriptions, HCF (HART COMMUNICATION FOUNDATION) device descriptions or company specific electronic device descriptions for field devices not having a uniform form, or language by means of a first compiler or generator; and converting the syntactically and semantically correct standard device descriptions further into corresponding software modules by means of a second compiler.
