Abstract

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 re…
