Definitions

  • the invention relates to a variable field device for process automation.
  • Field devices are often used in automation and process control technology, which measure process variables (sensors) or control controlled variables (actuators) in an industrial process.
  • Field devices for flow, level, differential pressure, temperature determination etc. are generally known.
  • the field devices are usually arranged in the immediate vicinity of the process component concerned in order to record the corresponding process variables, mass or volume flow, fill level, pressure, temperature, etc.
  • the field devices deliver a measurement signal that corresponds to the value of the detected process variables.
  • This measurement signal is forwarded to a control unit (e.g. programmable logic controller PLC, waiting or process control system PLS).
  • a control unit e.g. programmable logic controller PLC, waiting or process control system PLS.
  • the process is controlled by the control unit, where the measurement signals from various field devices are evaluated and, based on the evaluation, control signals are generated for the actuators which control the process flow.
  • Controllable valves that regulate the flow of a liquid or a gas in a pipeline section are to be mentioned as an example of actuators.
  • the signal transmission between field device and control unit can take place in analog or digital form (e.g. current loop or digital data bus).
  • analog or digital form e.g. current loop or digital data bus.
  • Known international standards for signal transmission are 4-20 milliampere current loops, HART®, Profibus®, Foundation Fieldbus® or CAN-Bus®.
  • the signal processing in the field device and the communication of the field device with the control unit or other field devices is becoming more and more complex.
  • various hardware components with corresponding software are implemented in the field device.
  • the software that runs as a sequence program in a microprocessor is usually very flexible and can be easily replaced.
  • the disadvantage of using software is that data processing takes place sequentially and is therefore relatively slow.
  • Hardware components on the other hand must hold a certain functionality that is hard-wired into special blocks (IC's). Examples include ASICs (Application Specific Integrated Circuits) or SMDs (Service Mounted Devices). These modules are very application-specific and can, for example, perform an FFT (Fast Fourier Transformation), which is very computation-intensive, extremely quickly.
  • FFT Fast Fourier Transformation
  • the communication of the field device with a higher-level evaluation unit also takes place partly via analog hardware components or via a digital data bus.
  • Each field device normally consists of different hardware components that determine the functionality of the field device. Different field devices, such as Coriolis mass flow meters or magnetic inductive flow meters MIDs, have completely different hardware components. Even for one and the same field device, for example a Coriolism mass flow meter, e.g. Different hardware components are required for communication.
  • a Profibus module is required to connect to a Profibus, and an FF module is required to connect to a Foundation Fieldbus. If the field device is to deliver a frequency, pulse or current signal, a corresponding hardware component is required.
  • a trend with field devices is that they should always be more compact.
  • the components, especially the hardware components are moving ever closer together on the respective circuit boards.
  • a limit has almost been reached here.
  • the hardware components must be tested after the circuit boards have been fitted.
  • a large number of test pads are provided on the underside of a printed circuit board, which can be contacted via so-called needle adapters. Only certain parts of the circuit can be tested in isolation.
  • Coriolism mass flow meter is replaced by a magnetic inductive flow meter in the field, the entire field device must be replaced today.
  • the object of the invention is to provide a variable field device for process automation which does not have the disadvantages mentioned above, which is particularly very flexible, has a compact design, is made from a few components, has a high level of safety and reliability and at the same time is inexpensive and is easy to manufacture.

  • a digital signal processor DSP is connected downstream of the sensor unit SE.
  • the digital signal processor DSP is connected to a system processor MP.
  • the system processor MP is connected to the data bus line DBL via a communication unit CE.
  • the system processor MP is connected to an analog unit AE, which has several analog inputs and outputs I / O.
  • a display operating unit AB which is also connected to the system processor MP, serves to display the measured value and for manual input.
  • the voltage supply of the sensor S1 is ensured by a voltage supply unit SV, which is connected to the various hardware components of the sensor S1 (shown in dashed lines). Power can be supplied externally or via the DBL data bus line.
  • the digital signal processor DSP and the system processor MP are each connected to watchdogs WZ1, WZ2 and EEPROM memories E1, E2.

  • the sequence program for the embedded controller is loaded into the memory M.
  • such logic modules are also referred to as SoPC systems or programmable chips.
  • a reconfigurable logic module LB By using a reconfigurable logic module LB, a Coriolis mass flow meter can easily be replaced by a magnetic inductive mass flow meter MID or any other field device. All that is necessary for this is the corresponding reconfiguration of the logic module LB when the system starts by means of new memory information in the memory areas A and B.
  • parts of the communication module can also be integrated in the logic module LB. This means that a sensor designed for the HART ⁇ protocol can easily be converted into a sensor suitable for Profibus® or FF. To do this, only the corresponding area of the logic module LB must be configured when the system is started.
  • a reconfigurable logic module LB By using a reconfigurable logic module LB, the number of parts in the manufacture of a field device is considerably reduced. Another advantage that the field device according to the invention offers is that new test strategies are possible. In principle, any area, ie functionalities, of Logic module LB can be isolated and monitored. To do this, the logic module only has to be configured accordingly and the signals tapped or added at corresponding test points.
  • reconfigurable logic modules With the help of reconfigurable logic modules, it is possible to configure hardware components and thus easily change the functionality and behavior.
  • the hardware components can thus be adapted to different tasks and functionalities.
  • Inputs and outputs I / Os can be easily defined.
  • function blocks e.g. Flexible Function Blocks (Foundation Fieldbus® Organization) or Profibus® Function Blocks (Profibus® Organization) can be easily defined and modified in terms of hardware and software.
  • the function block (Flexible Function Block or Profibus®) is loaded into the reconfigurable logic module and generates its I / Os itself. This means that an LB logic module can be used for various functionalities, depending on what is loaded for a function block.
  • the essential idea of the invention is to flexibly design field devices in a wide range by using a reconfigurable logic module.
  • the invention is of course not only limited to the field devices field, but can also be used with corresponding sensors and actuators in motor vehicle construction.
