Abstract
In a field device for process automation, a reprogammable logic device is used, in order to achieve a high flexibility as regards hardware components.
Claims10
A variable field device for process automation, including:
- a superordinated control-evaluation unit;
- a sensor module SM for measured-value detection of a process variable in an application;
- a signal processing module SPM connected to said sensor module SM;
- a communication module CU;
- and
- a processor module PM, which is connected with said communications module CU for connection of the field device with said superordinated control-evaluation unit, wherein:
- said signal processing module SPM and said processor module PM are provided in the form of a reprogrammable logic device LD;
- and
- at system start, both hardware and software are configured on said reprogrammable logic device LD in a desired fashion thereby matching the particular demands of the application of said sensor module SM.
