The Plant Sequencing-Decouple module is responsible for sequencing pumps, interlocks, and stages of a discrete plant system to maintain a decouple flow setpoint. This module accepts as inputs a process variable, a setpoint, an Up Delay, a Down Delay, a Number of Devices Running, a System Interlock Status, a Stabilize Delay, a Start-Up Delay, Minimum Running Devices, Device Mode, and a System Enable. Based on the input commands and the attribute settings, the module outputs a state for sequencing pumps, interlocks, and stages of a discrete plant system and an output for the number of devices to run.
You can view and modify the modules in this group’s logic.
