Microchip LAN9662/LAN9668 PROFINET Operation

This application note from Microchip Technology provides comprehensive guidance on utilizing the LAN966x family of Time-Sensitive Networking (TSN) capable Ethernet devices within PROFINET and PROFINET@TSN industrial networks.

Key Features and Technologies Covered:

• PROFINET and PROFINET@TSN protocols
• TSN functionalities including Shaping, Time-aware shaping (TAS), Queue system, Cut-through, Preemption (IEEE 802.Qbu/3br), and Per-stream filtering (PSFP)
• Time synchronization using IEEE 802.1AS (gPTP)
• Protection and network redundancy mechanisms (FRER, MRP, DLR)
• PROFINET Conformance Classes (CC-A to CC-D)
• IO Controller (IOC) and IO Device (IOD) concepts

The document details the operation of the LAN9662 (4-port TSN endpoint) and LAN9668 (8-port TSN switch), offering insights into their hardware capabilities and software integration, including practical examples with Siemens PLCs and RT-Labs software.
