  • Sensors such as liquid level gauges, flowmeters, pressure and temperature measuring devices, pH redox potential measuring devices, conductivity measuring devices, etc., which record the respective process variables such as level, flow, pressure, temperature, pH or conductivity, are used to record process variables.
  • Actuators such as valves or pumps, via which the passage of a liquid in a pipe section or the level in a container can be changed, serve to influence process variables.
  • field devices are all devices which are used close to the process and which process or process-relevant information.

  • the higher-level units are control systems or control units, such as PLC (programmable logic controller) or DCS Distributed Contra! System).
  • the higher-level units serve, among other things, for process control, process visualization, process monitoring and commissioning of the feeder units.
  • One or more such higher-level units can be connected directly to the fieldbus to which field devices are connected, and / or to a higher-level communication network.
  • a field device a plurality of parameters is provided. Parameters of a field device are, for example, a measuring range, limit values, units, etc.
  • the functionality of the field device can be adapted according to the respective intended application .
  • the configuration of a field device is usually carried out during commissioning of the field device. If changes are to be made during operation, some configuration can also take place during operation. Changing, activating and / or deactivating parameters of a field device is done by a write access to the parameters. By a read access parameters of the field device can be read, a change of the parameters does not take place.
  • operating programs For accessing parameters of field devices, in particular for reading and writing parameters from fidatories, operating programs, which are also referred to as operating tools (or operating tools), are provided.

  • Operating tools can also have other functions in addition to the explained access to field devices. So far, access rights are statically defined in a field device, which means in particular that once defined or defined access rights to parameters of the field device remain unchanged in time (provided they are not changed again). During the commissioning of a field device, a parameter change is relatively uncritical because it does not directly affect the process of a plant.
  • a field device In a plant of process automation technology, a field device is usually not in communication with one but with several operating tools. Coordination of the accesses from the various operating tools often does not take place. This can lead to two operating tools accessing parameters of a field device at the same time or in such short intervals of time that unpredictable behavior and / or an error occur in the current application. For example, the case may occur that a first operating tool accesses the field device and loads all or part of the parameters of the field device to the associated processor unit on which the operating tool is implemented. This data is then available as offline data, which means that a change of the same (in the processor unit) does not directly affect the associated parameters in the field device. The parameters are then changed offline, for example, by the operating tool and then loaded back into the field device.
  • the changed parameters are then available as online data in the field device.
  • a parameter change in made the field device it may be the case that the parameter change of the first or the second operating tool is inadvertently overwritten or that the parameter change of the first operating tool is not compatible with the parameter change of the second operating tool. This can lead to unpredictable behavior of the process or to the occurrence of errors.

Alternatively, the communication connection be formed via a service interface of the field device to which a corresponding operating device, such as a portable handheld device, is connected.

  • the field device F3 checks whether the read request is encompassed by the predefined access rights, depending on the operating state in which the field device F3 is located and depending on the profile information of the second operating tool. Reading parameters here is not critical for the process. Read access is included in the predefined access rights and can be performed without restriction.
  • the service person 6 also wishes to carry out a change of a parameter of the feeder F3 via the handheld terminal 8 and thus via the third operating tool.
  • the field device F3 After placing a write request from the third Constechnik- tool to the Fetd réelle F3, the field device F3 checks depending on the operating state in which the field device F3 and depending on the profile information of the third operating tool, whether the write request of the predefined access rights becomes. As explained above, the field device F3 is in an operation state with write access disabled. The field device F3 is therefore blocked for another write. The service person 6 is informed both via an indication of the field device F3 and via a display of the handheld terminal 8 that the feeder F3 is currently locked by the first operating tool and a write access is not possible. As soon as the session with the first operating tool has ended, the blocking in the field device F3 is released. A corresponding message is displayed both on the display of the Feiduzes F3 and on the display of the manual control unit 8.
  • the present invention is not limited to the embodiment explained with reference to FIG.
  • the present invention is applicable not only to sensors and actuators as field devices. Rather, the advantages mentioned above also result when using remote I / Os, gateways and linking devices.
  • a remote I / O which is connected to a field bus and is connected via analog lines to one or more simple field devices, be operated according to the inventive method.
  • another bus system such as a HART® bus system, a Foundation® Fieldbus bus system, etc., can also be used.

Abstract

La présente invention concerne un procédé pour faire fonctionner un appareil de terrain (F1 ; F2 ; F3) de la technique d'automatisation des processus, qui est en liaison de communication avec au moins un outil de manipulation. Dans le cas d'une demande d'accès d'un outil de manipulation sur l'appareil de terrain (F1 ; F2 ; F3), l'accès accordé par l'appareil de terrain (F1 ; F2 ; F3) dépend alors de l'outil de manipulation particulier qui pose la demande d'accès et de l'état de fonctionnement dans lequel se trouve l'appareil de terrain (F1 ; F2 ; F3).
