Abstract
Methods and apparatus to manage process plant alarms are disclosed. An example disclosed method comprises performing a first data structure query to obtain an alarm state for a process plant alarm based on a process plant operating state, and configuring handling of the process plant alarm based on the obtained alarm state.
Claims21
A method comprising:
- performing a first data structure query to obtain an alarm state for a process plant alarm based on a process plant operating state;
- and
- configuring handling of the process plant alarm based on the obtained alarm state.
An article of manufacture storing machine readable instructions which, when executed, cause a machine to:
- perform a first data structure query to obtain an alarm state for a process plant alarm based on a process plant operating state;
- and
- configure handling of the process plant alarm based on the obtained alarm state.
An apparatus comprising:
- a machine accessible memory;
- an alarm behavior rules data structure stored on the machine accessible memory, the alarm behavior rules data structure defining, for a process plant alarm, a plurality of alarm states for respective ones of a plurality of operating states;
- and
- an alarm manager to receive an operating state selection, to obtain an alarm state from the alarm behavior rules data structure based on the received operating state selection, and to configure handling of the alarm based on the obtained alarm state.
