Variable alarm setpoints and priorities

A computing device, comprising:

• a processor;
• and
• a memory storing non-transitory machine-readable instructions to cause the processor to:
• store a rate of change of a process variable associated with a process at an industrial site in the memory;
• receive process data from equipment at the industrial site over a period of time;
• calculate an updated rate of change of the process variable associated with the process at the industrial site based on the process data;
• store the updated rate of change of the process variable in the memory;
• determine an alarm priority, an unsafe level, or an alarm limit based on the updated rate of change;
• transmit the alarm priority, the unsafe level, or the alarm limit to an event and alarm system;
• and
• cause the event and alarm system to generate an alarm for the process based on the transmitted alarm priority, unsafe level, or alarm limit, in real time during operation of the process.

A system, comprising:

• an event and alarm system;
• and
• a computing device communicatively coupled to the event and alarm system, wherein the computing device is configured to:
• receive process data from equipment at an industrial site over a period of time;
• calculate a rate of change of a process variable associated with a process at the industrial site based on the process data;
• update the rate of change of the process variable with the calculated rate of change;
• store the updated rate of change of the process variable in memory of the computing device;
• determine an alarm priority, an unsafe level, or an alarm limit based on the updated rate of change;
• and
• transmit the alarm priority, the unsafe level, or the alarm limit to the event and alarm system;
• and
• wherein the event and alarm system is configured to:
• receive the alarm priority, the unsafe level, or the alarm limit;
• and
• generate an alarm for the process based on the alarm priority, the unsafe level, or the alarm limit in real time during operation of the process.
