WebTRAC™ is Chemtrac's process monitoring and control system. The WebTRAC™ system includes a graphical user interface that resides in the Web Access Controller (WAC), and remote I/O modules to interface to field instrumentation. WebTRAC™ can be customized to perform monitoring and control functions of any typical plant application. WebTRAC's versatility allows secured accessibility via a local area network (LAN), wide area network (WAN), Internet, telephone line, or direct pc connection. WebTRAC™ uses standard internet browsers and open industry standard protocols to create a common environment that connects and shares information. WebTRAC™ is scalable to allow unlimited number of inputs and outputs.

WebTRAC™ is designed to work seamlessly with Chemtrac's Streaming Current Monitors, Particle Counters and Particle Monitors, and will easily accept signals from other analytical field devices such as Turbidimeters, Chlorine residual analyzers, pH, etc.

Web Access Controller (WAC): The WAC is a compact pc platform with an integral hard drive. It is a panel mounted industrial hardware package specifically designed for mechanical room or factory floor settings. The standard configuration of the WAC provides integrated control, supervision, and data management solutions for integration of multiple system protocols. The controller provides management of global control functions, data management across multiple networks, and hosts multiple users accessing the system over local area, wide area, internet, or dial up modem networks.

Platform

The I/O Node incorporates multiple channels of analog and digital I/O. These I/O are controlled by the advanced Neuron® control and communications chip. User defined algorithms and functions can be programmed for the I/O Node using LonWorks programming tools. The program is stored in non-volatile memory so it is retained even after loss of power.

WebTRAC™ is a built-to-fit process control system designed to perform user defined process functions. The graphical user interface allows password assigned users to view, edit, and control from any standard web browser. Proprietary software or a dedicated computer is not required.
