摘要:
The invention relates to a method for reducing parameter data to be transferred during uploading and/or downloading of parameter settings between field devices and/or a control center, wherein the parameter data comprise information on an operating condition of said field device and/or information on a process variable recorded by means of said field device and/or identification date of said field device, wherein the data present after a reset process or upon start-up of said field device are established as default parameter data, wherein modification information as to whether said parameter deviates from the default parameter data is saved for each parameter, wherein only that parameter data is transferred for which a deviation from the default parameter data is determined by the modification information.

The invention relates to a method for regulating the power supply of a number of field devices (S1, S2, S3, A1, A2), which are connected via a data bus line (DBL) and are supplied with power via this data bus line (DBL). According to the invention, the current demand of individual field devices (S1, S2, S3, A1, A2) is determined and the current consumption of the field devices (S1, S2, S3, A1, A2) is adjusted by means of corresponding control signals. This enables the current consumption of individual field devices (S1, S2, S3, A1, A2) to be centrally adjusted and thus adapted to the process conditions.
