LTP5903-WHR SmartMesh WirelessHART Embedded Manager


Typical Application

LTP5903-WHR Typical Application


SmartMesh WirelessHART wireless sensor networks are self managing, low power networks built from wireless nodes called motes. Based on the WirelessHART (IEC62591) standard, the LTP5903-WHR runs SmartMesh WirelessHART network management software to monitor and manage network performance and provide a data ingress/egress point via a UART interface. It provides the core networking functionality, enabling the network to achieve unsurpassed levels of resilience, reliability, and scalability with advanced network management and comprehensive security features.

The LTP5903-WHR is designed for use in line-powered gateways and controllers, such as WirelessHART Gateways, and enables customers to integrate a standards-based wireless sensor network that provides scalable bidirectional communications.

The embedded network manager offers a comprehensive software application programming interface (API) to deliver rich and flexible functionality without complex coding. This API also provides full visibility and control over network configuration, security administration, network status, and performance statistics. The network-ready embedded manager enables industrial automation vendors to integrate advanced wireless sensor networking intelligence into monitoring and control solutions with low risk and rapid time-to-market.

SmartMesh networks are highly configurable, and allow the user to trade off performance parameters (e.g. latency and power consumption). The Current Calculator spreadsheet enables users to estimate average current consumption and average latency in a particular network topology. In addition, Starter Kits enable users to evaluate network performance in real-world application environments.
