A control and/or monitoring system is disclosed. In an embodiment, the system includes a host device on which an application for generating an Ethernet frame for deriving information about an industrial Ethernet network can be run and an industrial Ethernet tunnel device which is adapted to communicate with the host device. The system is configured to inject the Ethernet frame for deriving an information about an industrial Ethernet network and/or about one or more of the industrial Ethernet devices through the industrial Ethernet tunnel device and to receive an answer in an Ethernet frame format in the host device. An industrial Ethernet tunnel device and a method for control and/or monitoring of one or more devices in an industrial Ethernet network are also disclosed.
