RTU / PLC Systems

Leverage the power of automation and digital technology.

RTU’s are used in a variety of applications across many sectors. Applications include remote monitoring and control of fixed asset such as wellheads, valve stations, tank farms, cathodic protection sites, custody transfer metering stations, transmission pipelines, power generation and compression facilities, just to name a few.

An increased need for operational efficiencies, asset optimisation, safety, environmental protection and compliance are key across all industries. As such, the reliance on real-time data and analysis is ever increasing. This ability to provide accurate, real-time data enables management, engineering and maintenance teams to make better, more informed decisions relating to both the asset and resources.

RTU’s also enable local historical data logging, providing an onsite record in the event of communications failures, with the ability to “backfill” data within SCADA once site communications has been restored

Several practical considerations must be taken into account when choosing an RTU system to deliver benefits. Key features required in an RTU are –

  • Resilience to the site environment.
  • An ability to operate with minimal drain on local power resources.
  • Flexibility with respect to I/O, communications and possible future expansion, along with the processing power required to perform complex process control algorithms reliably and autonomously.

It is also beneficial that an RTU has extensive diagnostics capability and a low Mean Time to Repair (MTTR), to reduce the time required for technicians to spend on site, in the unlikely event of a failure, once again improving operational efficiency, productivity and personnel safety.

RTU’s offer a solution to many of the common issues facing asset owners and we welcome the opportunity to discuss your needs in greater detail.
