Definitions

  • the invention relates to a method for automatically adapting a bus-compatible field device to the bus protocol used on the fieldbus.
  • Such field devices are level measuring devices, mass flow measuring devices, pressure and temperature measuring devices, pH redox potential measuring devices, conductivity measuring devices, etc., which as sensors detect the corresponding process variables level, flow, pressure, temperature, pH value or conductivity value.
  • Electrode cleaning systems, calibration systems and samplers are particularly worth mentioning here.
  • Input / output input units so-called remote I / Os, are also referred to as field devices.
  • Actuators are used to influence process variables.
  • Field devices are often connected to fieldbus systems (Profibus, Foundation Fieldbus, etc.), which enable digital data exchange between the field devices and higher-level units, for example control systems or control units. These higher-level units are mainly used for process control and process monitoring.
  • Profilebus Foundation Fieldbus, etc.
  • Data is exchanged via the fieldbus in the form of telegrams (frames) that have a very specific structure that is prescribed by the bus protocol used.
  • the user data is packed into a series of control and monitoring sequences in accordance with the respective bus protocol.
  • the Profibus PA protocol (Data Link Layer) is described in more detail in the EN50170 standard.
  • the Foundation Fieldbus specifications are summarized in the publicly available "Foundation Fieldbus Technical Specifications”.
  • Field devices must be adapted to the respective fieldbus system already during the manufacture of the field devices.
  • a corresponding fieldbus stack program (fieldbus stack) is implemented in the field device.
  • the task of the fieldbus stack is to obtain the user data from the telegrams sent via the fieldbus and to forward them to the respective application running in the field device for further processing.
  • Stacks for the different fieldbus systems are e.g. supplied by TMG-itec or Softing AG.
  • the memory requirement for a Profibus PA stack is around 50 kB and for a Foundation Fieldbus FF stack around 250 kB.
  • a special fieldbus stack is implemented in the field device, eg a Profibus stack
  • this field device can only be used in a Profibus fieldbus system.
  • Use in a Foundation Fieldbus fieldbus system or other systems is not possible.
  • the object of the present invention is therefore to provide a method for automatically adapting a bus-compatible field device of process automation technology to the protocol used on the fieldbus, which is simple and inexpensive to carry out and which is suitable in principle for any protocols.
  • the essential idea of the invention is to receive telegrams from the fieldbus and to forward them to various fieldbus stacks stored in the field device and to process them there.
  • the fieldbus stack that can process telegrams properly, ie with which further processable user data can be extracted from the telegrams, is selected. With this selected fieldbus stack, further data exchange with the fieldbus takes place.
  • Fig. 2 bus-compatible field device
  • FIG. 4 flow chart of the inventive method.
  • the data bus D1 works according to the HSE (high speed ethemet) standard of the Foundation Fieldbus.
  • the data bus D1 is connected to a fieldbus segment SM1 via a gateway G1, which is also referred to as a linking device.
  • the fieldbus segment SM1 consists of several field devices F1, F2, F3, F4, which are connected to one another via a fieldbus FB are connected.
  • the fieldbus FB also works according to the Foundation Fieldbus standard.
  • the field device F1 is shown in more detail in FIG. 2.
  • This field device is an example of a temperature transmitter with a sensor.
  • the field device F1 has a microcontroller ⁇ C which is connected to a sensor MA via an analog-digital converter AD.
  • a display / operating unit AB which is also connected to the microcontroller ⁇ C, is optionally used to operate the field device and to display various information.
  • Flash, EEProm and / or RAM memory serve as memory for programs and parameters.
  • the microcontroller ⁇ C is connected to the fieldbus FB via a fieldbus interface FBS. Fieldbus telegrams can be exchanged between the field devices and the higher-level units WS1 or WS2 via the fieldbus FB.
  • the Profibusframe FR1 consists of several data fields; SD3 start field, DA destination address, SA sender address, FC function code, data and FCS frame checksum.
  • the data field data can e.g. B. contain measured values, queries etc.
  • the field device F1 receives a telegram T1, which is structured according to the rules of the Foundation Fieldbus.
  • the telegram T1 contains a series of control sequences according to the fieldbus telegram used (here Foundation Fieldbus).
  • This fieldbus telegram T1 is forwarded by the fieldbus interface FBS to the fieldbus stack program ST1 after a successful CRC check.
  • the ST1 fieldbus stacking program is a Profibus stacking program (Profibus stack). Since the telegram T1 is structured according to the Foundation Fieldbus rules, user data from this telegram can also be used With the help of the batch program ST1, an application cannot be forwarded.
  • Profile stack Profibus stacking program
  • the fieldbus stacking program ST1 signals a processing error.
  • the batch program ST2 is then loaded and the next telegram T2 sent via the fieldbus FB is received.
  • the telegram T2 is transferred to the stack program ST2 and processed in it.
  • the stack program ST2 is a Foundation Fieldbus stack program (FF stack)
  • user data can be obtained from the telegram and passed on to the corresponding application in the field device F1.
  • field device F1 can e.g. Diagnostic programs started, measured values read out or parameter values changed. If the telegram T2 is correctly processed in the fieldbus stacking program ST2, this stacking program will continue to be used to read subsequent telegrams T or to send telegrams from the field device F1 via the fieldbus.
  • FF stack Foundation Fieldbus stack program
  • a major advantage of the method according to the invention is that it can be easily adapted to new protocols. All that is required is the appropriate one Batch program can be stored in the field device so that telegrams can also be processed with this.
