Abstract: A field device of automation technology having a function for checking quality of a network connection includes an operating electronics and at least one communication interface for connecting to a communication network having one or more network participants and for building a communication connection, wherein a communication stack and a PHY are associated with the communication interface, wherein the communication stack and the PHY are embodied continually to gain and to store communication information regarding the communication connection, wherein the operating electronics is embodied to read out communication information from the communication stack and from the PHY, and by means of an algorithm to subject the communication information to computation and based on the result of the computation to classify a communication state.

Abstract: The present disclosure relates to automation technology. A first gateway is connected via a first communication network to a field device—and a second gateway is connected to the field device via a second communication network. The first and the second gateway are connected to a control unit. The first communication network and the second communication network are connected to a control room. The control room switches over to the other communication network and establishes a communication connection therewith if a problem is detected in the previous communication connection. Communication access to the first gateway is implemented in the control unit, and communication access to the second gateway is implemented in the control unit via a second driver. The control unit continuously analyses the first communication network and the second communication network and in the event of a control room switchover, switches over to the gateway of that network.

Abstract: A device for the extraction of user data out of Ethernet telegrams sent from a field device comprises an input interface and an output interface for connecting to an Ethernet data line, wherein the input interface is designed to receive Ethernet telegrams transmitted via the Ethernet data line; an electronics unit which is designed to evaluate the received Ethernet telegrams and to extract a value of at least one process variable out of the user data portions of the received Ethernet telegrams; and an output unit for outputting the determined process variables. The invention also relates to a system comprising the device according to the invention.
