Plant areas are monitored for temperature, humidity, sweating, and any potential water leaks, Macko said. Every plant item that can be monitored — from the electrical incoming power supply, phase failure relay, generator, chillers, air conditioning units, UPSs, breakers, water leakage sensors, temperature and humidity sensors, to the fire panel, vesda, and gas firing pin. Monitoring is achieved via high level interfaces Modbus and Bacnet, and some low level interface for basic plant items. (Photo courtesy: Intervolve)
