Central Plant Interconnection Network Output modules are directly connected to Network Input modules in Central Cooling with Optimization Applications, unless otherwise indicated. The Central Plant Interconnection modules provide connection between the controller and the associated pump, tower, or other controlled device. For some of these modules, this connection occurs when the application is split across multiple controllers.

The following table describes these modules and lists the applications in which they are used.

Name	Definition
CPO-30 CLGMODE	Communicates to the CPO-30 system that the system is in mechanical cooling mode (chillers only), free cooling mode, or transitioning from one mode to another. The CPO-30 system calculates setpoints differently depending on whether the system is in mechanical cooling or free cooling mode. This output is analog with values 0, 1, 2, and 3 as indicated below: 0 - Mechanical cooling mode. The chillers are enabled and provide 100% of the cooling for the plant. 1 - Transitioning from mechanical cooling to free cooling mode. 2 - Free cooling mode. The chillers are disabled and the free cooling heat exchanger(s) provide 100% of the cooling. 3 - Transitioning from free cooling mode to mechanical cooling.
