Devices supported
The following table lists the devices that support the Alarm An indication (visual and/or audible) that alerts an operator at a Station of an abnormal or critical condition. Each alarm has a type and a priority. Alarms can be assigned either to individual points or for system-wide conditions, such as a controller communications failure. Alarms can be viewed on a Station display and included in reports. Experion classifies alarms into the following types: - PV Limit - Unreasonable High and Unreasonable Low - Control Failure - External Change. Set Point Also known as SP. The desired value of a process variable. Setpoint (SP) is an analog point parameter, and the value is entered by the operator. The setpoint can be changed any number of times during a single process. The setpoint is represented in engineering units. See SP in the Control Builder Parameter Reference. See also: analog point, parameter, process variable. Value group, and their formats.
