METHOD FOR OPERATING A FIRST AND AT LEAST ONE SECOND FIELD DEVICE
The invention relates to a method for operating a first and at least one second field device (F1, F2), wherein the first field device (F1) and the at least one second field device (F2) are in a first communication connection (N1) for process controlling and/or process monitoring, preferably as a participant of a first network, e.g. via the first network, wherein a second communication connection (N2) is provided, in particular established, between the first field device (F1) and the at least one second field device (F2), via which second communication connection (N2) a communication can be carried out that is independent of the process controlling and/or process monitoring.
