  • Publication number: 20100125427
    Abstract: A field device for measuring a filling level, a pressure or a density of a medium in a container includes data memory with two memory areas that are separated from one another. First data for safety-critical program modules is stored in the first memory area. Second data for safety-uncritical program modules is stored in the second memory area. The two memory areas are separated from one another. All access to these memory areas is controlled by a memory management unit.

  • Publication number: 20100121999
    Abstract: A method for generating a device description for a measuring apparatus in a target field bus protocol is described. The method comprises the reception of a first device description of the apparatus. The first device description of the apparatus comprises at least one variable. The at least one variable is related to a storage cell of the apparatus. The target field bus protocol is selected from a plurality of field bus protocols, and at least one block is formed from the at least one variable. The at least one block has a maximum block size that corresponds to the smallest maximum block size of at least two field bus protocols of the plurality of field bus protocols. The maximum block size can be transmitted via a field bus with a single request when the respective field bus protocol is used. Subsequently, the at least one block is provided as device description for the apparatus in the target field bus protocol.

  • Publication number: 20100114530
    Abstract: An electronic module for level measurements, pressure measurements or density measurements is disclosed. In the module, a safety-relevant function is transferred into an area that is categorized as safety-uncritical. In order to prevent malfunctions, a diagnostic function is performed in the safety-critical area of the electronic module in order to check the transferred function. This diagnostic function is also checked with respect to its effectiveness during the safety-oriented operation. Suitable measures can be initiated in case an error is detected.

  • Publication number: 20080154522
    Abstract: Described is a method for automatically initiating an update of a parasitic echo storage device in a fill level meter operating according to a runtime method. In this method individual echoes of echo curves of different ages are allocated, according to their typical echo characteristics, to global echo groups so that subsequently, after examining the behaviour over time of the echoes of the respective global echo curves, it can be judged whether the echoes of the respective global echo curves are useful echoes or parasitic echoes. Starting from this classification, the parasitic echo storage device is then updated with the oldest echoes of the corresponding global echo groups. Apart from the method for updating a parasitic echo storage device described is also an evaluation device for implementing the method as well as to a computer program and a computer program product for carrying out the method.

  • Patent number: 6725718
    Abstract: Described is a method for a coarse differentiation between a liquid and a bulk material of a filling material present in a receptacle using a filling level measuring device that scans a reflected echo signal. The coarse differentiation is made in dependence on the width of the individual echoes of an envelope curve in an echo signal. Alternatively, the coarse differentiation may also be made in dependence on the number of equidistant echoes in an echo signal, or in dependence on the detection of a stirring apparatus. All these alternatives may also be combined with each other. Also described are devices and filling level measuring devices configured for the realization of the methods.

  • Patent number: 6684919
    Abstract: A method and apparatus for non-contact determination of overfilling of a receptacle filled with a filling product generates an envelope curve from echo signals reflected on a filling product surface. An amplitude of the echo signals is mathematically processed in a predetermined short range of the envelope curve, and is compared to a predetermined reference value (x). When the amplitude exceeds the predetermined reference value (x), a signal representative of overfilling of the receptacle is outputted. Further, described are an evaluation arrangement for realizing the method and a filling level measuring device equipped with such an evaluation arrangement.

  • Publication number: 20020103946
    Abstract: The invention relates to master or slave devices for data communication on a bus, to which bus various devices are attached. The master device (2) is able to address a slave device (1) attached to the bus with messages using a plurality of different protocols and to ascertain whether the slave device responds correctly to the protocol. Thus it can work together with slave devices which command only a single protocol, and the protocols employed by the different slave devices can be different ones. At the same, a slave device capable of using a plurality of protocols is proposed, which is able to evaluate messages received over the bus (3) according to a plurality of different protocols and, when the evaluation according to one of the employed protocols yields an executable instruction, the slave device is able to execute that instruction.
