A field device for process instrumentation, in particular a measuring transducer, comprising an analogue output to which a two-wire line is connectable for transmitting an analogue output signal. The output circuit contains a controller with an actuator connected downstream for the analogue output signal. A monitoring unit monitors whether an actuating signal remains within a predeterminable value range to monitor the output circuit for correctly setting the loop current. If the actuating signal is outside the value range, an indicator signal is output to a computing unit so that suitable measures can be introduced in response to an error state that has thus been identified.

A method for accurately acquiring multiple analog input signals that are converted using a plurality of A/D converters into corresponding digital single measured values. A first measurement averaging cycle having a predetermined total number of measuring intervals is predetermined by a higher-order control unit. First and second input signals are acquired by first and second A/D converters in a first and second number of measuring intervals, the second number being smaller than the first number. The first and second input signals are averaged to form first and second measured values, respectively. The first input signal is acquired by the second A/D converter in a third number of measuring intervals as at least one further single measured value. A message is output if a deviation of the at least one further single measured value from a single measured value of the first input signals measured by the first A/D converter or from the first measured values averaged up to that point exceeds a maximum permissible absolute value of the deviation.

A signal converter device has a programmable logic circuit, wherein a number of binary input signals are being transmitted from the outside of the signal converter unit. The programmable logic circuit is programmed by a programming in such a way, as to detect binary output signals from a number of logic functions. The output signals are output by the signal converter device to the outside. The logic functions are designed in such a manner, that the output signals are determined exclusively by logic associations of the input signals. The output signals are at least partially transmitted to drives. Programming is in such a way, that for at least two drives, output signals to be emitted to the drives are determined uniformly.

In normal mode, a central unit of an electronic control device receives desired and actual values for determining desired current values which are transmitted to an electronic drive unit. The central unit of the electronic drive unit receives the desired current values for determining drive signals for circuit breakers. In monitoring mode, the central unit of the electronic control device checks whether an connected electric motor is in a safe state. If not, the control device transmits disconnection signals to a disconnection device and to the drive unit. The central unit of the electronic control device generates checking information for the drive unit. In the monitoring mode, the central unit of the drive unit checks whether a disconnection signal is transmitted to the central unit and whether the checking information is correct.

In a method for monitoring a stationary condition of a drive device, a monitoring device provides the drive device with a temporally varying monitoring signal which, when a sensor device connected to the drive device functions properly, modulates a sensor output signal of the sensor device in accordance with the monitoring input signal. The monitoring device receives the sensor signal and monitors it for the presence of a corresponding signal component. In the absence of such a signal component, the monitoring device controls a safety device which converts the drive device into a safe state. When the drive device is controlled by means of at least two phase-shifted current regulators, it is possible for the monitoring device to monitor an output signal of at least one of the current regulators for constancy and to control the safety device when the output signal of the at least one current regulator changes.

For real-time communication between a number of network subscribers in a communication system using Ethernet physics, the slave units are synchronized to the master unit in that each slave unit is clocked via a respective timer with a predetermined overall cycle time, which timer is set cyclically by the reception of respective slave-specific synchronization information which is determined by the master unit. In this case, each timer in a slave unit automatically starts a new cycle once the predetermined overall cycle time has elapsed, even in the absence of the respective synchronization information. Access control for the transmission mode and reception mode between the network subscribers is provided using a timeslot access method.
