Telemetry plays a key role in automation, allowing data from a range of assets to deliver the promised benefits of Big Data. This has come about over the last few years as technology has advanced and communication links improved, making the remote telemetry unit (RTU) a reliable and cost-effective alternative to manual monitoring and data collection. RTUs have evolved into multipurpose devices that are used for remote monitoring and control in automated systems. They are commonly found in industrial environments, and serve a similar purpose to programmable logic circuits (PLCs) but offer additional benefits, such as greater resilience, for example. They are capable of automating part or whole of an industrial process or assembly line.
