1. A field device comprising:

  • at least one actuator and/or sensor configured to alter and/or sense a control and/or process variable in a manufacturing field;

    a wireless transmitter and/or receiver configured for wireless data communication between the field device and a remote device when activated;

    an interface configured to receive operating power;

    an energy buffer configured to store energy from the received operating power and to supply the stored energy to the wireless transmitter and/or receiver during wireless data communication; and

    a controller configured to evaluate the stored energy available in the energy buffer prior to activation of the wireless transmitter and/or receiver and delay activation of the wireless transmitter and/or receiver when the evaluation indicates that the stored energy in the energy buffer is insufficient to sustain operation of the wireless transmitter and/or receiver during wireless data communication.
