摘要： The disclosure relates to a method for increasing the availability of displacement/position measuring systems on the basis of potentiometers with a slider tap in a closed control loop, the controller of which is formed by a microcontroller which is supplied with the position of the slider via an analog/digital converter. At least part of the sensor range of the potentiometer is scanned on request by presetting a sequence of manipulated variables and an available control loop variable which represents the position value at a high sampling rate outside process tasks is recorded, to determine the exact position of a defective slider position of the potentiometer by evaluating the variable. The reference variable of the control loop is overloaded in a defined manner within the process task such that the defective slider position is passed over during the displacement/position measurement and an intact slider position is reached.

摘要： A device for activating an electropneumatic valve of a pressure medium-operated position controller, in which the valve is activated by a manipulated variable. To achieve a blocking fail-safe behavior in case of a failure of a pressure medium, the device includes means for detecting the current position of a booster stage downstream of the valve and assigning the manipulated variable based on the detected position, and means for measuring a first variable to be influenced by the position controller. The device includes an evaluation unit configured to determine an expected directional reaction of the first variable to the assigned manipulated variable, compare the expected reaction with the measured reaction, determine a pressure medium failure as a fault situation if the expected reaction does not coincide with the measured reaction, and assign, as a new manipulated variable for the valve, an emergency signal generating a blocking fail-safe behavior of the valve.

摘要： A method for increasing the availability of displacement/position measuring systems using a potentiometer with a slider tap in a closed control loop. The controller of the potentiometer is formed by a microcontroller which is supplied with the position of the slider via an analog/digital converter. The operating range is shifted within the sensor range in a direction of one of two limits of the operating range at least by a distance between the other of two limits of the operating range and a defective slider position by temporarily interrupting an operative connection between the displacement pick-off on the actuator and the potentiometer shaft.

摘要： A method and an electronic device are provided for logging process variables of a bus-controlled automation system in which process variables which are relevant to evaluation are buffered in at least one digital field device and are subsequently read, for the purpose of evaluation, by a central computer unit which is connected to the field device via a data bus. Process variable values which are relevant to evaluation are buffered in the field device in the form of a message, a plurality of equidistantly successive process variable values are recorded as messages, where the first process variable value is assigned a time stamp recorded for each message, and further process variable values are stored in further identical messages.
