2 T SUPERVISORY CONTROL AND DATA ACQUISITION (SCADA) SYSTEM T Description. Furnish and install Supervisory Control and Data Acquisition (SCADA) in accordance with the Contract Documents. The SCADA Control Panel will use IEEE 802.3u, 100 Mbps, Fast Ethernet protocol to communicate with the Department s Ethernet network. Voltage/Current Analog sensors, monitors, and position indicating contacts will be installed to provide inputs to the SCADA system. The remote sensors, monitors and components will be connected to the SCADA system with power and communication cables labeled and stored neatly in raceways to form a complete system. Some equipment, such as cabinet door switches, will send information indirectly to the SCADA system. A technician from the Department will load the final programming at the primary SCADA control panel necessary for final acceptance and commissioning tests. T Materials. Furnish all labor and materials necessary to provide, install, and test a Supervisory Control and Data Acquisition (SCADA) System in each local hub cabinet and master hub building. Refer to the Supervisory Control and Data Acquisition Details in the ITS Plans.
