ENHANCED DEVICE ALARM IN PROCESS CONTROL SYSTEM

摘要

PROBLEM TO BE SOLVED: To integrate display device alarms with process alarms by enhancing device alarm messages. SOLUTION: The system receives a device alarm message from a field device and the device alarm message has a message field including a first set of device information. The system appends a message field containing a second set of device information associated with the field device to the device alarm message based on the first set of device information to form an enhanced device alarm message and selects a device alarm table based on the second set of device information within the enhanced device alarm message. The system maps the first set of device information within the device alarm message to the selected device alarm table to identify a set of information fields containing displayable alarm information and displays a portion of the displayable alarm information.
