Patent ID: 8234357

Claim:
A method for servicing field devices of process automation technology utilizing a device-independent operating program SP running in a computer unit CU and requiring device-specific description files DD 1 -DD 6 for accessing parameters and/or functions of field devices F 1 -F 6 , wherein the device-specific description files are called during run time of the operating program SP via a preprocessing program and are stored in the computer unit CU, comprising the steps of: storing first and second preprocessing programs IP 1 , IP 2 in the computer unit CU; connecting the computer unit CU with the field device F 1 -F 6 to be serviced; loading the device-independent operating program SP; selecting the field device F 1 -F 6 to be serviced in the operating program SP; calling the device-specific description file DD 1 -DD 6 of the field device F 1 -F 6 to be serviced via the operating program SP through the preprocessing program IP 1 or IP 2 associated with the device-specific description file DD 1 -DD 6 ; and changing parameters of the field device F 1 -F 6 by means of the operating program SP, wherein: the preprocessing programs IP 1 , IP 2 are interpreter programs; and the interpreter programs interpret the device-specific description files DD 1 -DD 6 during run time of the operating program SP, when information from these files is required.
