An improved system and method for monitoring a fieldbus network. The improved method and monitor utilize multiple filters with the capability of simultaneously capturing packets from more than one fieldbus and the ability to apply multiple filters to any single fieldbus. Filtered packets are captured as capture documents and stored in the monitor's memory storage. Filtered packets can be displayed, in real time, on the monitor's display screen. The improved monitor is configured to perform post-capture filtering of captured packets. Post-capture filtering does not destroy data. The improved monitor permits dynamic altering of filter settings. Using this feature, the user can initiate capture using a first filter settings, alter the filter setting while packets are being captured, and apply the altered filter setting to the fieldbus without terminating capture. The altered filtered settings are applied to the fieldbus substantially instantaneously and the packets captured under the altered filter settings are displayed.

[ What is claimed is:] [1.] A method of monitoring fieldbus packets on a fieldbus network using a monitor configured on the fieldbus network to receive the fieldbus packets, wherein the monitor includes a display screen, the method comprising:initializing two or more packet filters;combining said two or more packet filters into a single combined filter;filtering said fieldbus packets with said single combined filter to produce filtered data;capturing said filtered data, wherein said capturing includes storing said filtered data in a memory of said fieldbus monitor; andseparating said filtered data into filtered packet data for each of said two or more packet filters, wherein said separating is performed based on said two or more packet filters.
