The AquiNet Fieldbus Network System is a complete solution for monitoring large numbers of multiple sensing devices via a single touch screen interface, on a simple two- wire bus network. The AquiNet system consists of a touch screen user Graphical User Interface (GUI) communicating with a master generator linked to Zone Communication Modules (ZCM’s) via a two core ? eldbus network. ZCM’s can be added to any leak detection device with volt free contacts. When the relay changes over (close on alarm), a signal is sent via the network to a ?eldbus generator, and the alarm with its location is displayed on the screen. Each generator can monitor up to 100 ZCM’s. Multiple generators can be linked to create very large networks. The master generator interfaces with the touch screen panel that runs the graphical user interface (GUI) which displays alarms and current system status. The GUI can be tailored speci?cally for the client’s requirements.
