Definitions

  • the invention relates to an adapter unit for data communication of a field device of automation technology with a field bus, the field device having a diagnosis / service interface which provides field device-specific data.
  • the focus is particularly on field devices that have a diagnosis / service interface, from which data can be tapped directly on site, for example, to provide the service technician with more detailed information.
  • a field device is, for example, the "Liquiphant M", which is manufactured and sold by the applicant.
  • the field device-specific data is usually an identification of the field device by the so-called identification resistance, on the basis of which, for example, the field device type can be identified
  • the data also includes the switching signal, which is obtained from the field device on the basis of the measured values Field device used, for example, for overflow protection, the switching signal indicates that the fill level has been exceeded. The switching signal is then used to stop a pump, for example, or to close an inlet.
  • the data are the sensor signals, for example the liquiphant is the amplitude and frequency of the
  • the fill level can be concluded on the basis of both variables - however the frequency is usually evaluated.
  • the frequency depends e.g. depends on whether the vibratable unit - in the case of the liquiphant a tuning fork - vibrates freely in air, or whether it is covered by the medium to be monitored.
  • the advantage if e.g. not only the switching state, but also frequency and amplitude are known, e.g. in that an approach on the tuning fork can be recognized. If the medium sticks to the oscillatable unit as an attachment, the oscillation frequency is reduced even if the tuning fork is not covered by the medium. This can be dangerous with the so-called no-load protection, if it must be prevented that a level is not fallen below.
  • the object is achieved in that the adapter unit can be connected to the diagnosis / service interface and that the adapter unit transmits field device-specific data from the diagnosis / service interface via the fieldbus.
  • the idea is to enable communication between the diagnosis / service interface and the fieldbus via an adapter unit
  • the component that is in the device itself for fieldbus-compatible field devices - for this purpose there is, for example, the Liquiphant PA from the applicant - to be relocated to the outside.
  • This also results in a modular and pluggable structure that enables the field device to be upgraded.
  • the field device-specific data is then transferred from the diagnosis / service interface via the fieldbus.
  • an evaluation unit has all the relevant variables that are only accessible via the diagnosis / service interface when queried directly. This increases the security of the entire system because more data is available.
  • One application of the invention is that the communicated
  • Data for function monitoring of the field device can be used. However, the normal switching signals e.g. generated to control a system.
  • the actual function of the field device is thus not restricted, rather more data is made accessible.
  • the advantages of the invention are thus that the adapter unit does not only use existing ones, e.g. built-in field devices can be upgraded, but that complete process or production systems can also be upgraded. Furthermore, nothing changes in the actual function of the field device; it still provides the same and necessary basic signals, but the adapter unit provides access to further signals from which more information can be obtained.
  • the design of the adapter unit is such that it connects to the field device as simply as possible, e.g. can be put on. This also means that the adapter unit gives standard or alarm signals when it is supplied with energy, i.e. can deliver signals per se, but e.g. is not or is not correctly connected to a measuring device.
  • An advantageous embodiment provides that the adapter unit can be connected to a power supply unit. This configuration has the advantage that the specifications of the field device are not influenced.
  • the field device is not disturbed or influenced by the adapter unit, since both are in separate circuits. So the big advantage that the adapter unit can be used without the function of the field device being disturbed.
  • the adapter unit has at least one microcontroller. Via this microcontroller or microprocessor, field device-specific data of the field device are fetched, evaluated, and prepared for communication with the fieldbus and made accessible for communication.
  • microcontroller transmits the field device-specific data according to the HART® protocol via the fieldbus. This in connection with the own power supply for the adapter unit enables the field device not to be influenced by the adapter unit.
  • the field device is a level sensor.
  • the applicant's Liquiphant M is to be mentioned here, which has a corresponding diagnosis / service interface. Such an interface is important so that data communication can be carried out without further modification to the field device and without further influencing the field device.
  • Fig. 1 a block diagram for the connection of the field device via the adapter unit with a fieldbus.
  • the field device 5 has a Diagnostics / service interface 15.
  • the Liquiphant M is, for example, four sockets on which, among other things, the identification resistance for identifying the field device, the determined switching status - covered or free - and the sensor signal - amplitude and frequency of the vibration - can be tapped.
  • Other field devices have special diagnostics / service interfaces, which also enable other signals and information.
  • the field device 5 is fed by a power supply unit 25.
  • a switching signal is fed from the field device 5 to a control unit 30 in order to trigger switching operations there, for example.
  • the field device 5 is used for overflow protection.
  • the field device 5 outputs a switching signal when the medium has reached a predetermined fill level.
  • This switching signal can then result in a control unit that, for example, a pump is switched off.
  • the detailed field device-specific data can only be obtained without an adapter unit 1 in such a way that, for example, a service person picks it up on the field device 5.
  • the adapter unit 1 communicates this data via a fieldbus 10 and is therefore also available at a remote location. This then also enables so-called predictive maintenance, for example, the possibility of monitoring the functionality of the field device. It is important, for example, to know the frequency and the amplitude of the vibrations in order to make statements about a possible approach to the vibratable unit of the field device 5.
  • the adapter unit 1 has a microcontroller 20 which transmits the data of the field device 5 in accordance with the HART® protocol. Since the adapter unit 1 has its own power supply unit 25, the data can thus be transmitted to the fieldbus 10 without influencing the field device 5. This means that there are no effects on the field device 5 due to the adapter unit 1. The great advantage of the adapter unit 1 is that more information is available from the measurement and that there is no retroactive effect on the field device 5 at the same time.
