M340 PAC with RTU module

The Modicon M340 Process Automation Controller‟s

NOR0200H RTU module allows data from a complex control application to be integrated into a telemetry and remote SCADA system.

The NOR0200H RTU module provides a range of

communication services, including open protocols, for operating in a telemetry and remote SCADA environment. It is suitable for use in applications where the control complexity requires the power of the M340 PAC including water & wastewater, renewable energy, gas transportation, and so on.

Accutech wireless instrumentation

Figure 26: Accutech wireless instrumentation

The self-powered wireless Accutech range allows for rapid deployment of instrumentation solutions for remote sites.

With a wide range of available instruments for temperature, pressure, flow, level, valve control and more, Accutech is ideally suited to many industrial applications including upstream oil & gas, and applications in water & wastewater that are “outside the process.”

Distance, hazarous environments and absence of power are some of the hurdles faced when process variables are difficult to reach and expensive to support. With operational efficiency as the primary goal, the deployment of self-powered wireless instrumentation provides process knowledge in a cost effective manner.

Supporting a range up to 1500m (5000 ft) from an Accutech base station, the Accutech wireless sensors are easily configured in a highly scalable deployment. Up to 10 years operation on a single battery eases maintenance. Each Accutech base radio can support up to 100 field instruments with up to 1 second sampling. Up to 256 base radios are supported.

Over the air configuration and firmware upgrade are available from the Accutech Manager software configuration tool.

Integrate the Accutech remote instrumentation network with an RTU, PLC, DCS or SCADA master through Modbus communication with the base radio, or through analog and switch output modules.

The BR20 base radio option for integrated Trio K-Series backhaul radio allows an Accutech system to connect directly on a Trio K-Series wireless network without the need for additional communication equipment.

Accutech system architecture

The sample Accutech system architecture shown depicts a typical gas production installation. The architecture includes a number of Accutech wireless instruments, a BR20 base station module and a SCADAPack 334 RTU interconnecting with a SCADAPack 4102 multi-variable transmitter (labeled as Wellhead Separator Outlet Gas Flow).
