A process control arrangement (PKA), having a number of fieldbus systems (DP, PA, FH), especially different fieldbus systems (DP, PA, FH), and having a number of fieldbus interfaces (PAP, PAP, PAP), wherein each of the fieldbus systems (DP, PA, FH) is connected to at least one of the fieldbus interfaces (PAP, PAP, PAP), wherein the fieldbus interfaces (PAP, PAP, PAP) serve for communication between the fieldbus systems (DP, PA, FH) and a communication plane (ET) superordinated to the fieldbus systems, only a first of the fieldbus interfaces (PAP) is directly connected to the superordinated communication plane (ET), and wherein the fieldbus interfaces (PAP, PAP, PAP) are connected in series with one another beginning with the first of the fieldbus interfaces (PAP).

Process control arrangement for a plant of process and/or automation technology connecting a superordinate communication plane with fieldbus systems

A method has been invented for dynamically adapting a diagnostic system, which is at least partially implemented in a controller, and which has at least one diagnostic block. In such case, the controller is, in communication via a fieldbus with at least one field device, wherein the at least one diagnostic block is embodied in such a manner, that through this, various diagnostic parameters of the at least one field device are capable of being read. Additionally, the at least one diagnostic block is implemented (or provided) in the controller and/or in the at least one field device. The method includes steps as follows: Reading at least one diagnostic parameter of the field device by the diagnostic system; checking by the diagnostic system, referencing the at least one read diagnostic parameter, of whether a predetermined criterion for an alarm or error report is fulfilled; if such a predetermined criterion is fulfilled, automated checking by the diagnostic system, on the basis of predetermined rules, of whether an adapting of the criterion is possible in such a manner that the adapted criterion for an alarm or error report is no longer fulfilled; and outputting an alarm or error report only if such an adapting of the criterion is not possible.

Method for dynamically adapting a diagnostic system

A method for operating a fieldbus interface (FI) connected to a fieldbus of process automation technology. The method includes the following: tapping data traffic on the fieldbus by the fieldbus interface; and registering tapped configuration information relative to cyclic data traffic on the fieldbus by the fieldbus interface.
