  • Field device for determining a measured variable and method for communication
    Patent number: 10436618
    Abstract: A field device for determining a measured variable and that also issues a measured value in the case that an error state is present. The field device includes a sensor unit, a signal outlet, and an output device. The output device issues a state signal and/or a measuring signal via the signal outlet, wherein the state signal is assigned to a state of the field device. Additionally, the output device fulfills a safety function in the case that the state of the field device arises and thereby issues both the state signal assigned to the state as well as the measuring signal. Furthermore, there is a method for communicating the presence of a state of a field device.
