Claim Text:
1. A process communication device comprising: a process communication interface configured to communicate with at least one field device on a process communication loop in accordance with a process communication protocol; a controller coupled to the process communication interface; a rules store coupled to the controller, the rules store having at least one process communication packet rule that is based on the process communication protocol a device description store coupled to the controller, the device description store having at least one device description related to a process variable measured by the at least one field device and wherein the at least one field device is described by the at least one device description stored in the device description store; and wherein the controller applies the at least one process communication packet rule and the at least one device description to at least one process communication packet received from the process communication interface, and generates event information when a process communication packet fails the at least one process communication packet rule or if the at least one communication packet is not in accordance with the at least one device description for the at least one field device; and a network interface coupled to the controller, wherein the controller is configured to forward the process communication packet through the network interface if the process communication packet passes all process communication packet rules.
