Abstract
A networking system is discussed. The system may be used for industrial networks where access to field device data is valuable. Commands, such as read or write requests to particular field device data, may be encapsulated within messages conforming to an object-oriented protocol, such as, for example, Common Industrial Protocol (CIP). Responses to the commands may also be encapsulated within CIP messages. The encapsulated commands and responses may be transmitted between various devices of an industrial network, including a controller and a gateway device, such as a multiplexer, of the industrial network. Encapsulating the commands and responses may provide a tunneling mechanism allowing a controller complete access to the data of the field devices in communication with the gateway device.
