Abstract
A field device, comprising a sensor, and a control/evaluation unit. The control/evaluation unit is implemented on an application-specific integrated circuit—an ASIC—which, in at least a first section and in a second section, is embodied as a dynamically reconfigurable logic chip. In each of the two sections, in each case, a measuring path composed of a plurality of function modules can be configured; wherein the individual sections are spaced apart from one another in such a manner, that a temperature and/or a voltage change in one of the sections has no influence on the other section or the other sections. The control/evaluation unit partially dynamically reconfigures the function modules in the measuring paths as a function of the particular defined safety-critical application, so that the field device fulfills the required safety standard.
