There is continuous development, and the management of network-connected devices and the expansion of Server-Client networks can be hard and cumbersome. To correctly safe networks, a multistage procedure is needed incorporating danger assessment, planning, design, implementation, and upkeep for a comprehensive defense-in-depth method. A essential aspect of defense-in-depth is the general network system architecture and the network segmentation strategy. A correctly planned and executed network architecture and segmentation approach lays the foundation for safety and simplifies expansion and upkeep of the network.

Each and every town received equivalent gear and the systems are independent of each and every other. The CR1000 was employed as a remote terminal unit (RTU) at each and every web site and also as the programmable logic controller (PLC) at every base station. The dataloggers communicate with each other working with Campbell’s RF450 spread-spectrum radio. At each town hall there is a master station that consists of a CR1000 and an NL120 Ethernet interface. LoggerNet and VTScada run on Windows 7 PCs and communicate with the CR1000 master unit over Ethernet connections.
