Abstract
Devices in a process control system communicate by data messages over a communication medium segment. Each device includes a communication controller that maintains an order of occurrence of events received from and transmitted to a communication medium. The communication controller includes an order of occurrence identification (OOO_ID) counter and an event queue memory. The event queue memory sequentially stores an event type identifier for each event that is processed by the communication controller. The OOO_ID counter provides an OOO_ID to associate with each event type identifier.
