Abstract
Capturing messages exchanged with field devices in an industrial process without disrupting communication of the messages. A diagnostic driver embedded within a gateway device detects abnormal conditions in connections between the gateway device and the field devices. The diagnostic driver captures messages indicative of the abnormal condition without disrupting message communication. The driver is capable of transmitting captured messages, on demand, to a workstation computing device for diagnosis of the abnormal condition.
