<p>A process communication device (100) includes a process communication interface (114) for communicating on a process communication loop in accordance with a process communication protocol. A controller (106) is coupled to the process communication interface (114). A rules store (116) is coupled to the controller (106), and has at least one process communication packet rule that is based on the process communication protocol. The controller (106) applies the at least one process communication packet rule to at least one process communication packet received from the process communication interface (114), and generates event information when a process communication packet fails at least one process communication packet rule.</p> |
