Field device for automation systems

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.
