Managed Water Plant Connectivity
A European water authority needed to extend its telemetry system used for automation, control and monitoring of assets. The telemetry system measures parameters from a number of different types of assets; monitoring both digital inputs, such as pump runs and faults, and analogue inputs such as PS, pressure, chlorine flow etc. Alarms can be triggered on the status and value of these signals and recorded as events. The telemetry network requires connectivity devices that are environmentally hardened, certified, secure and centrally managed with resilient communications paths, supporting both Ethernet, serial and I/O. Example usage could be control of booster stations to reservoirs. The applications do not require significant bandwidth but do require a reliable, secure service.
Virtual Access Solution
The client chose substation hardened routers with dual path 3G, 4G, DSL, integrated RTU functionality, advanced security and Activator for service automation. Virtual Access provide a single device that can be used for automation of new and legacy assets that require I/O, serial RS232/RS485, and Ethernet interfaces with wireless broadband and optional DSL.
A key difference in the Virtual Access solution was the carrier-grade Activator provisioning and monitoring system designed to scale to tens of thousands of devices. This means that devices do not need to be pre-configured and can be installed without staff skilled in networking. The solution allowed the ware authority to maximise the level of process and field deployment automation by integrating with northbound IT systems and enabled devices behind the VA router in the substations’ cabinets to be configured identically while still being individually addressable from the central SCADA systems.
