Abstract
A system couples fieldbus data from a fieldbus line to a network line. The system includes a data format converter that converts the data to USB data. A coupler that includes a first insulating barrier is coupled in cascade with the converter. A host receives the USB data. The host has a data server interface and a network connection. The data server interface presents the data to the network line. A regulator couples power between the host and the fieldbus line with the regulator including a second insulating barrier. Data and power are isolatingly coupled between the fieldbus line and the network line.
