The gateway uses a 2.4 GHz, IEEE 802.15.4 radio to gather measurement data from the sensor network and a 10/100 Mbits/s Ethernet port to provide flexible connectivity to a Windows PC or NI LabVIEW Real-Time PAC, as seen in Figure 1. With this flexibility, you can create simple, stand-alone wireless monitoring networks or completely integrated wired and wireless measurement solutions that feature access to the full breadth of NI hardware and software platforms. LabVIEW integration with NI WSNs delivers a common development environment for your applications as well as rapid application development, easy network configuration, remote data access, and the ability to program and customize measurement node behavior. The 9 to 30 VDC externally powered gateway offers -30 to 70 °C operating temperatures, 50 g shock ratings, and a compact, 2U form factor. Up to 36 measurement nodes can communicate with a single gateway, and you can configure the Ethernet settings of the gateway for DHCP, static, and link-local IP address configurations. Wireless Networking The NI WSN system is built on a low-power, reliable IEEE 802.15.4 network. The Ethernet gateway coordinates the wireless network, performing functions such as device authentication, message buffering, and network topology administration. The gateway, routers, and end nodes work together to form a mesh network. Measurement nodes can operate as routers or end nodes, providing the flexibility to extend the range of your sensor network. When nodes are configured as routers, they can repeat messages from end nodes and extend network range Figure 1. NI WSN systems provide flexible connectivity to Windows or LabVIEW Real-Time host controllers. while acquiring measurement data. NI Wireless Sensor Network Ethernet Gateway To save power and increase reliability, the network delivers a maximum theoretical throughput of 250 kbits/s. In general, this correlates to between 30 and 60 samples per minute per channel on the WSN measurement nodes. You can configure the network to operate on any of the 14 wireless communication channels to optimize performance and ensure coexistence with other wireless devices. The external, omnidirectional antenna and internal power amplifier offer up to 300 m outdoor range with line of sight. Programming You can integrate your NI WSN measurement data directly into LabVIEW. After adding the WSN Ethernet gateway to a LabVIEW project, the nodes configured with the gateway in MAX are automatically added underneath the gateway in the project, giving you instant access to their I/O and properties. Software Overview With NI-WSN software, you can easily configure your sensor network in the NI Measurement & Automation Explorer (MAX) configuration utility and quickly extract measurement data from your wireless sensor network with the LabVIEW graphical development environment. Network Configuration MAX offers an intuitive user interface to add and remove measurement nodes and configure wireless settings. Upon connection, the WSN-9791 Ethernet gateway is autodetected under Remote Systems in MAX, and you can assign measurement nodes to the gateway. The gateway maintains a list of nodes (by serial number) that have been authorized for network access. When a node powers up, it scans for available networks, locates either a gateway or router, and attempts to join it. If the gateway has the node in its list, the node joins the network, downloads the latest configuration from the gateway, and begins its normal operation of acquiring measurement data and controlling digital I/O. If a node is unable to connect, it executes a retry sequence with increasingly higher wait periods beginning with one minute between connect attempts and ending with 55 minutes between connect attempts. This preserves battery power if a gateway is offline. MAX also offers an overview of the nodes connected to your network including their last communication time, battery status, and link quality. In addition, MAX provides an interface to set the wireless communication channel, configure the gateway IP address, and wirelessly update firmware on the measurement nodes. Figure 3.

(L by W by H). The front of the gateway offers power, status, and activity LEDs in addition to a reset button that you can use to reboot the device. The power connector and Ethernet port are located on the front, while the DIN-rail and panel mount plate screw holes are located on the back of the device. The gateway also includes integrated panel mount holes that are located on the side of the device. Consult the WSN-9791 user guide for detailed mechanical information. Figure 4.

Gateway External Features DIN-Rail and Panel Mount Plate Screw Holes Advanced WSN Architectures You can combine NI WSNs with other NI platforms to customize and enhance your measurement capabilities. You can complement your NI WSN with PACs, vision systems, or even human machine interfaces (HMIs) to create a fully integrated solution that meets your unique application needs. Integrated Panel Mount Holes Accessories NI WSN accessories feature options for gateway and measurement node mounting as well as a weatherproof enclosure for outdoor use of the measurement nodes. Available mounting accessories include options to panel mount and DIN-rail mount WSN measurement nodes and gateways. The NI WSN-3281 magnetic panel mount kit provides easy setup and takedown on virtually any metal surface. For high shock and vibration applications, NI recommends a panel mounting configuration rather than DIN-rail.
