Abstract

The invention relates to a field device for automation systems, comprising a unit for internal data organisation, means for recording process parameters and/or means for outputting regulation parameters, means for processing signals according to the recorded regulation parameters or the regulation parameters to be output, and at least one communication interface. The means and the communication interface thus communicate with a unit for internal data organisation in order to exchange data between each other. A transaction manager unit, which is provided to control blockings, transactions and/or users, is used to control the access via the means and via the at least one communication interface to the data of the unit for internal data organisation between the means, the at least one communication interface and the unit for internal data communication.

Claims

1. A field device for automation systems, comprising:

a unit for internal data organization,

means for recording process parameters and/or means for outputting regulation parameters,

means for processing signals according to the recorded process parameters or the regulation parameters to be output, and

at least one communication interface,

wherein the means for recording process parameters and/or the means for outputting regulation parameters, the means for processing signals and the communication interface are communicating with the unit for internal data organization for the exchange of data between them,

wherein a transaction manager unit is provided between the means for recording process parameters and/or the means for outputting regulation parameters, the means for processing signals, the at least one communications interface and the unit for internal data organization, said transaction manager unit managing blockings and at least one of transactions and users to control access by the means for recording process parameters and/or the means for outputting regulation parameters, the means for processing signals, and the at least one communication interface to the data of the unit for internal data organization.

2. The field device according to claim 1, wherein the transaction manager unit comprises a transaction service entity which makes available at least one transaction protocol for coordinating the transactions with other transaction manager units.

3. The field device according to claim 2, wherein the transaction protocol is the Transaction Internet Protocol.

4. The field device according to claim 2, wherein the propagation of transactions with other transaction manager units and distributed transactions can be realized via the transaction protocol of the transaction service entity.

5. The field device according to claim 2, wherein the transaction protocol can be mapped onto other communication protocols which are used by the at least one communication interface.

6. The field device according to claim 2, wherein the functions:

manager of blockings, manager of transactions and/or manager of users are made available to the at least one communication interface or the users of the at least one communication interface directly or via the transaction protocol of the transaction service entity by mapping onto the communication protocol used by the interface.

7. The field device according to claim 1, wherein the unit management of blockings, the unit management of users and/or the transaction service entity of the transaction manager unit lie in layers and the unit management of users is arranged vertically.

8. The field device according to claim 1, wherein at least one interface is provided for manual input and/or for the output of display data.

9. The field device according to claim 1, wherein the transaction manager unit has means for ensuring at least two-phase transactions.

10. A field device for automation systems, comprising:

a unit for internal data organization,

means for recording process parameters and/or means for outputting regulation parameters,

means for processing signals according to the recorded process parameters or the regulation parameters to be output, and

at least one communication interface,

wherein the means for recording process parameters and/or the means for outputting regulation parameters, the means for processing signals and the communication interface are communicating with the unit for internal data organization for the exchange of data between them,

wherein a transaction manager unit is provided between the means for recording process parameters and/or the means for outputting regulation parameters, the means for processing signals, the at least one communications interface and the unit for internal data organization, said transaction manager unit managing blockings and at least one of transactions and users to control access by the means for recording process parameters and/or the means for outputting regulation parameters, the means for processing signals, and the at least one communication interface to the data of the unit for internal data organization,

wherein the transaction manager unit manages transactions based on at least one of;

blockings, initiations, rejection of results, confirmation of results, allocation of blocking, access to objects of the internal data organization, ensuring at least two-phase transactions and other synchronization transactions.

11. The field device according to claim 10, wherein transactions managed by the transaction manager ensure the consistency of internal data organization via a non-interruptible sequence of access to its objects.

12. A field device for automation systems, comprising:

a unit for internal data organization,

means for recording process parameters and/or means for outputting regulation parameters,

means for processing signals according to the recorded process parameters or the regulation parameters to be output, and

at least one communication interface,

wherein the means for recording process parameters and/or the means for outputting regulation parameters, the means for processing signals and the communication interface are communicating with the unit for internal data organization for the exchange of data between them,

wherein a transaction manager unit is provided between the means for recording process parameters and/or the means for outputting regulation parameters, the means for processing signals, the at least one communications interface and the unit for internal data organization, said transaction manager unit managing blockings and at least one of transactions and users to control access by the means for recording process parameters and/or the means for outputting regulation parameters, the means for processing signals, and the at least one communication interface to the data of the unit for internal data organization,

wherein transactions managed by the transaction manager ensure the consistency of internal data organization via a non-interruptible sequence of access to its objects.
