This document provides an overview of the monitoring capabilities in the VDC 3D client software for a data center facility. It summarizes the key electrical, mechanical and environmental equipment that can be monitored on the main, ground and second floors, including power distribution units, generators, pumps, chillers, UPS systems, CRAC units, AHUs, fans and sensors. Monitoring points include status, alarms, electrical parameters and environmental data, obtained via protocols like MODBUS, DI and others. Floor plans can also be accessed for layout views.
