This module controls a proportional source within a control application. The module accepts as inputs, a mode, a process variable, a setpoint, and so on. Based upon the input mode and parameter settings, the module outputs a percent command and control status. It passes the outputs to the MSC module that controls the actual binary outputs. This module is a simplified version of Cooling Staged Outputs or Heating Staged Outputs and only supports three Mode states, namely, Off, Max and Control. This module also incorporates tracking the overridden value of the actual output object (AO, PAO). The module resets the PIDs to default tuning parameters if the Reset PID Tuning input is not Normal.
This module provides EWMA diagnostic values calculated by the PID. Controllers have the ability to collect data about their inputs, outputs, and internally calculated variables. Inside the controller, the EWMA minimizes memory requirements, reduces communication traffic, and provides an easy way to analyze collected data. See EWMA Diagnostics in the Commissioning a System section for more information.
