Important: As of Release 5.0, the Tower Sequencing-2 Speed v50 module replaces the Tower Sequencing-2 Speed module.

The Tower Sequencing-2 Speed module is responsible for sequencing two speed cooling tower fans to maintain a setpoint. This module accepts as inputs a mode, a process variable, a setpoint, a minimum on time, a minimum off time, a rotate now, process units, a device x runtime (where x is 1-6), and a device x enable (where x is 1-6). Based on the input commands and the attribute settings, the module outputs a control status and a device x out (where x is 1-12). 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.

You can view and modify the modules in this group’s logic.
