摘要： A method for initializing a communication link between a field device and a control unit according to a communication protocol is described. The communication protocol defines a broadcasting message with a data area. From the field device, a broadcasting message is generated and transmitted according to the communication protocol with a first datum in the data area. The first datum determines whether a communication connection is possible or not. The broadcasting message is received by the control unit and then, when the first datum determines the possibility of the communication connection, the communication connection is initialized by the control unit.

摘要： A method for operating a measuring device includes: storing a voltage membership function; assigning a voltage membership degree to a voltage fuzzy set of sufficient buffer voltages; storing an operating parameter membership function; assigning an operating parameter membership degree to an operating parameter fuzzy set of sufficient operating parameter values; determining an operating parameter value and measuring a first buffer voltage at a first time; executing a fuzzy algorithm that involves determining the voltage membership degree of the first buffer voltage using the voltage membership function, determining the operating parameter membership degree of the operating parameter value using the operating parameter membership function, and determining a result membership degree by combining the voltage membership degree and the operating parameter membership degree; and determining a further method step which requires no more than an available energy for a duration of an execution of the method step.

摘要： A system includes a field device and a control device. The field device includes a field device controller and a field device transmitter. The control device includes a control device controller and a control device transmitter. The field device transmitter and the control device transmitter have a transmission path between them. The field device controller and the control device controller are adapted for bidirectional transmission of messages between one another according to a communication protocol via the field device transmitter, the transmission path, and the control device transmitter. The communication protocol implements the transmission of messages with a master role and a slave role. The field device controller implements the master role and the control device controller implements the slave role. A related method is also disclosed.
