    • A field device for determining or monitoring a process variable in process automation. The field device includes: a sensor, which works according to a defined measuring principle; and a control/evaluation unit, which conditions and evaluates the measurement data delivered by the sensor; wherein the control/evaluation unit is embodied at least partially as a reconfigurable logic chip FPGA having a plurality of dynamically reconfigurable function modules; wherein an interface is provided, via which the control/evaluation unit receives sensor- and application-specific information concerning a defined sensor type in a defined process application; and wherein the control/evaluation unit so configures the function modules corresponding to the sensor- and application-specific information, that the field device is optimally adapted to the process variable to be ascertained, or to be monitored, and to the current process application of the field device.
    • 用于确定或监视过程自动化过程变量的现场设备。 现场设备包括:根据定义的测量原理工作的传感器; 以及控制/评估单元,其控制和评估由传感器传递的测量数据; 其中所述控制/评估单元至少部分地被体现为具有多个动态可重新配置的功能模块的可重构逻辑芯片FPGA; 其中提供了一个接口,所述控制/评估单元经由该接口在定义的过程应用中接收关于所定义的传感器类型的传感器和应用特定信息; 并且其中所述控制/评估单元配置与所述传感器和应用特定信息相对应的功能模块,所述现场设备最佳地适应要被确定或被监视的过程变量,以及当前过程应用 现场设备。
