Navionics Research Inc. is pleased to introduce a MODBUS\/TCP<\/strong> and MODBUS\/UDP CLIENT<\/strong> feature for its SCADA Server Software system!<\/p>\n

Has your Water Utility ever had the need to monitor Office and Plant Infrastructure<\/strong>, such as Power<\/strong>, Generator Status<\/strong>,\u00a0Physical Security<\/strong> (Entry & Motion Detection<\/strong>), Office Temperatures<\/strong>, Utility Consumption<\/strong> (Water, Gas, Electricity Meters<\/strong>), and Water Salesmen<\/strong>.\u00a0 If so, then this new software feature is made for you!<\/p>\n

Most often, the SCADA Server<\/strong> is staged at the Water District Office<\/strong>, and the RTU equipment<\/strong> is installed at remote pumping stations<\/strong>, water towers<\/strong>, metering stations<\/strong>, valve stations<\/strong>, etc..<\/p>\n

In order to monitor devices at the District Office, an extra RTU could be added to the system.\u00a0 However, Navionics Research recently developed and introduced an Economical\u00a0Software Feature<\/strong> that leverages the existing Server computer to co-function as a local MODBUS-over-Ethernet client \u2014 thereby obviating the need for an additional RTU and its associated expense.<\/p>\n

In a recent project, a client desired to monitor and alarm the Status of a Natural-Gas-Powered Backup Generator<\/strong> and Automatic Transfer Switch<\/strong> at the Water District Office using its SCADA system.\u00a0 The Water District office has two LANs (Local Area Networks)\u00a0\u2014 one business network and one control network.\u00a0 A MODBUS I\/O device was installed within the Automatic Transfer Switch enclosure and connected to the control\u00a0 network LAN.<\/p>\n
