    Abstract: A transmitting and receiving unit is provided for a field device for measuring a filling level or a pressure, which has an adaptive error counter. In this way, the sensitivity of the error detection may be adapted to individual needs or to the present length of the communications section. Thus, during wireless communication an optimally set error counter may fundamentally be used according to the distance to be covered without any adjustment needing to be made for this on the user side.

    Abstract translation: 为现场设备提供发射和接收单元,用于测量具有自适应误差计数器的填充水平或压力。 以这种方式,错误检测的灵敏度可以适应于个人需要或通信部分的当前长度。 因此,在无线通信期间,可以根据要覆盖的距离从根本上使用最佳设置的错误计数器,而不需要在用户侧进行任何调整。

    Abstract: A measuring apparatus comprises a receiving device, a processing device and a sending device. The receiving device is adapted to receive at least one telegram fragment, and the receiving device is adapted to determine a destination of the at least one telegram fragment, and depending on the destination of the at least one telegram fragment to set an operating state of the processing device. The receiving device is furthermore adapted, from the at least one telegram fragment, to prepare a telegram block, wherein the processing device is adapted, in a first operating state, to determine a telegram boundary of the telegram block, and to determine a type of the telegram block. The processing device is equipped, in a second operating state, to determine a telegram boundary of the telegram block, and to control the sending device such that the sending device sends a telegram subsequent to the telegram boundary.
