Systems and methods for alert device removal

摘要

The embodiments described herein include systems and methods for removal of alerts for a device. In one embodiment, an industrial process control system includes a controller a controller coupled to a field device. The industrial process control system further includes an alert server coupled to the controller. The controller is configured to detect, via a first protocol, removal of the field device and to communicate, in a second protocol, the removal of the field device to the alert server.

主权项

1. An industrial process control system comprising:
a controller configured to couple to a field device; an alert server configured to couple to the controller, wherein the alert server is physically detached from the controller; and a live list, wherein the controller is configured to query the live list to detect the removal of the field device, wherein the controller is configured to detect, via a first protocol, removal of the field device and to communicate, in a second protocol, the removal of the field device to the alert server, wherein the controller is configured to communicate the removal of the field device by transmitting to the alert server a message informing of the removal of the field device, wherein the alert server is configured to update an alarm process having a centralized repository of alarm information, the removal of the field device upon receipt of the message, wherein the update the alarm process comprises clearing the alarm information related to the field device from the centralized repository, wherein the controller is configured to collect additional alert information from the field device upon reattachment of the field device to the industrial process control system and the controller is configured to distribute the additional alert information to the alert server, and wherein the first protocol comprises a Fieldbus Foundation protocol, a HART protocol, or a combination thereof, and wherein the controller is configured to detect the removal of the field device by issuing a pass token to the field device and then querying the field device for the pass token.
