## Parameters

The following table lists the details of the PID Loop parameters.

Param | Address Line | Param Format | Access | Devices
--- | --- | --- | --- | ---

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. #1 SP The setpoint parameter of an analog point. The desired value of a process variable. Setpoint (SP) is an analog pointparameter, 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. #1

LOOP [n] FF Foundation Fieldbus. An enabling technology for dynamically integrating dedicated field devices with digitally based control systems. It defines how all "smart" field devices are to communicate with other devices in the control network. The technology is based upon the International Standards Organization's Open System Interconnection (OSI) model for layered communications. See also: Fieldbus Foundation._GAIN

Writable Controller Also known as remote terminal unit, RTU. A generic term for a device that is used to control and monitor one or more processes in field equipment. The most common control and monitoring device in an access control and security system is an access control panel. Other devices include security monitoring panels, elevator controllers, and fire monitoring devices. Controllers include programmable logic controllers (PLCs), loop controllers, bar code readers, and scientific analyzers. See also: C200 controller, control processor, CPM, hybrid controller, network node controller, PLC. Mode

LOOP [n] MODEIN
