Patent attributes
A method for replacement of an automation technology field device F1 connected with a fieldbus FB and having at least a first function block FB1 communicating via the fieldbus FB, via a communication relationship KR, with a second function block FB2 in a further field device F2 connected with the fieldbus FB Configuration data CD of the field device F1 are transmitted into a memory unit MU connected with the fieldbus FB and subsequently transmitted into a replacement field device F1′. Following installation of a selector function block SFB into the communication relationship KR between the first function FB1 and the second function block FB2 and connecting of the selector function block SFB with function block FB1′ of the replacement field device F1′ corresponding to the function block FB1, the selector function block SFB is switched so that the function block FB1′ communicates with the second function block FB2. This provides for simple device replacement in a fieldbus system.
