5 Predictive Maintenance in Industrial Environments

Another benefit of some Base-T1 PHYs is the ability to conduct diagnostics of the interface during data communication. Using a diagnostic tool requires a media access control interface to provide full access to the serial management interface of the PHY.

These are the current integrated diagnostic features of the TI PHYs:

  • Signal quality indication and cable quality indication
  • Time-domain reflectometry
  • Electrostatic discharge sensor
  • Voltage sensor
  • Temperature sensor
  • Pseudorandom binary sequence built-in self-test

For more details, see the diagnostic tool kit section of the DP83TG720S-Q1 1000BASE-T1 Automotive Ethernet PHY with SGMII and RGMII data sheet.

Base-T1 Ethernet technology features, such as low cable count and high bandwidth, can enable real-time diagnostic capability, including cable diagnostics that can detect when a cable is damaged or degrading. This detection feature allows engineers to replace cables during normal maintenance instead of performing production-line stops.
