Method for operating field devices of process automation technology with a device-independent operating program

摘要

Method for operating field devices of the process automation technology with a device-independent operating program BP, which runs on a computer unit RE and needs for accessing parameters and / or functions of field devices F1- F6 device-specific description files BD1-BD6, the runtime of the operating program BP via a Preprocessing program are called and stored in the computer unit RE, characterized by the following method steps: a) storage of a first and a second preprocessing IP1, IP2 in the computer unit REb) connecting the computer unit RE with the field device to be operated F1-F6c) loading the device independent Operating program BPd) Selection of the field device F1-F6 to be operated in the operating program BPe) Call of the device-specific description file BD1-BD6 of the field device F1-F6 to be operated via the operating program BP by the device-specific description file BD1-BD6 Preprocessing program IP1 or IP2, wherein the device-specific description file BD1-BD6 is a device description file (device description), and wherein the association between preprocessing program IP1, IP2 and device-specific description file BD1-BD6 via a version number of the description file BD1-BD6ff) change parameters of the Field device F1-F6 by means of the operating program BP
