Definitions
- the invention relates to a device for determining and / or monitoring a process variable
- the aim of the invention is to develop a field device with several functions, with at least one of the functions being a safety-relevant function, in such a way that, at least for the important safety function, the development guidelines which correspond to a specified safety standard (for example IEC 61508 ) are adhered to without preventing the integration in components not developed according to these guidelines.
- a specified safety standard for example IEC 61508
- the task here is to safely parameterize field devices that meet the security standard using tools that have not been developed in accordance with the security standards, such as local displays or PC tools.
- the aim of the invention is to ensure reliable parameterization, for example of the FMG 60 field device, under the conditions of the IEC61508 standard.
- the ToF Tool, AMS, PDM, etc. can be mentioned as tools.
- Fig. 1 the data flow for a safe parameterization of field devices is described.
- All parameters are defined as usual via selection menus. These parameters are sent to the device by the display or by other operating tools.
- the parameters are saved in the device. If the device is to be locked in terms of functional safety, the parameters can be converted into text by a software developed in accordance with IEC61508 in the field device.
- a password is entered first for locking. With this entry, certain parameters such as filters etc. are set to default values that are not used by the user when using the field device as e.g. SIL2 device can be edited.
- the safety-relevant and editable parameters are shown on the display again.
- the user must confirm each parameter individually or in groups. To do this, he changes the selection character "v" from No to Yes and confirms with "Enter”. With this confirmation, the parameter or the parameter group is pre-locked.
- the password must be entered again. If the password is entered correctly during confirmation, all safety-relevant and editable parameters are finally locked in the device. The password is no longer visible. It is represented by XXXX.
- the number of individual confirmations without the password should e.g. be at least three. A maximum of no more than ten confirmations
- a total reset is provided.
- a total reset sets all parameters to the default value.
- the password is deleted.
- the prerequisite for this procedure is that the device goes to fault current after a total reset and reliably monitors this state of the output current.
- a special feature of the FMG60 is that the parameters are sent to the Application ⁇ C via a Main ⁇ C, since the existing M-PI platform is to be used. In general, the procedure also applies to a one-processor solution or the Main ⁇ C is also developed in accordance with the requirements of IEC61508. The transfer and conversion into ASCII text by the application ⁇ C is not necessary.
- the main advantage of this approach is the independence of the tools. Since the entire safety-related software is in the field device, the operating tool does not have to be considered in the safety concept. It only needs to be able to display the text to be confirmed in full.
