LTP5903CEN-WHRB - LTP5903-WHR SmartMesh WirelessHART Embedded Manager

LTP5903-WHR SmartMesh WirelessHART Embedded Manager - Linear Technology（凌力尔特）

The LTP5903-WHR embedded network manager anchors the SmartMesh WirelessHART product line. 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. Sophisticated network management algorithms deliver dynamic network optimization and intelligent routing to achieve high reliability, low latency, and deterministic power management. 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.

Feature

Benefit

Highly Scalable

- Manages up to 250 motes (nodes), with optional software upgrade to 500 motes

- Time synchronized, Zero-Collision network protocol allows thousands of motes to operate in same radio space without interference

Advanced Network Management

Dynamically optimizes mesh connectivity based on the changing RF environment

Easily Expandable

Easy to add new motes because all devices are capable of being network routers. Authenticated motes listen and join mesh automatically.

Comprehensive Security Management

Security is comprehensive and multilayered including:

• Three levels of device authentication
• Strong AES-based data encryption
• Key management with multiple keys
• Message integrity checking

Dynamic Bandwidth

Configurable to support multiple report rates and message latencies within a single network

Load Balancing and Optimization

Adds more bandwidth for the busiest motes while maintaining normal traffic flow for the rest of network

Advanced RF Resiliency

Hops channels to avoid inevitable RF interference and creates redundant routes through the mesh

Deterministic Power Management and Optimization

Balances traffic so that power consumption is also balanced within the network

Auto-forming, Self-Healing, Self-Sustaining

• Automatically configures the network without requiring on site wireless expertise.
• Maintains multiple paths for each mote and detects and repairs broken paths.
• Regularly collects network health reports from all motes to dynamically optimize the network.

Network Management and Diagnostics

Monitor, configure and manage the network; includes APIs to build custom management and diagnostics applications.

Zero Collision Low Power Packet Exchange

Synchronized packet exchanges; no packet collisions on the network. Every packet is scheduled and synchronized for energy efficiency.
