Introducing the Distributed RTU™ Network
Proprietary & Confidential, 3 Remote Automation Solutions
The Distributed RTU™ Network - What is it?
• The Distributed RTU™ Network is a wireless network that was created to link field controllers as “nodes” spread across a wellpad or even between pads.
• Using a frequency-hopping, spread-spectrum radio network, the Distributed RTU Network enables sharing of any data in the controller’s database, including I/O, soft points, and other parameters.
• The Distributed RTU Network provides a unique and cost-effective solution to the challenges of difficult connectivity, remote point monitoring and control across a wide geographical area.
• The Distributed RTU Network structures data acquisition and transmission in a true peer-to-peer network (rather than a more traditional master-slave arrangement), uses wireless technology to improve data transmission, and enables you to design – and quickly re-design – both the network structure and the flow of data through the network.

Distributed RTU™ Network Features & Benefits Features
– Distributed, minimal featured remote RTU (DRTU) with I/O, logic, optional display, and visibility from any controller on the network
– Peer-to-peer addressable RTU network allowing any controller to browse and communicate with data residing in the peer controller over a wireless interface
– Intelligent control at remote location Key Benefits
– Reduced wiring cost by placing I/O at the point of use – Facilitates expansion on an as-needed basis to increase I/O and control
capabilities at the well pad – Reduced configuration by relying on browsing versus mapping of relevant data
between controllers – Increased reliability via local intelligence and the ability to make local logic
decisions at the point of use Differentiators
– Addressable wireless RTU network – NOT master-slave – NO Modbus mapping – RTU databases are “browsable” by other RTUs in the
network

Quick Setup - Nodes Each Node requires that a Network ID is set …
… and that a Channel is picked.
The Power Output must be set. The Node must be
configured as a Network Access Point or a Network Node.
Click Apply.
