EtherCAT Network Security Verification and Monitoring

KAS provides EtherCAT device verification and communication-monitoring capabilities that:

• Help detect unexpected or unintended changes to the configured EtherCAT network.
• Identify communication conditions that can affect network integrity or operation.

The KAS controller acts as the EtherCAT MainDevice.

During Startup and operation, the MainDevice uses information reported by the:

• Connected EtherCAT SubDevices.
• Configured EtherCAT network.
• EtherCAT communication diagnostics to verify devices and monitor network operation.

EtherCAT Security Profile

The EtherCAT Technology Group (ETG) defines EtherCAT cybersecurity measures in the ETG.1800 EtherCAT Security Profile.

• The profile provides a structured basis for selecting, implementing, and assessing appropriate EtherCAT security measures.
• Part 2 of the profile describes cybersecurity measures based on existing EtherCAT functionality and related process-management measures.

See these sites for information about EtherCAT cybersecurity and the related ETG measures:

• EtherCAT & Cybersecurity
• ETG.1800 EtherCAT Security Profile

• 
  
• • The EtherCAT capabilities description in this section supports applicable measures in the ETG.1800 EtherCAT Security Profile.
  • They do not, by themselves:
    • Provide cryptographic device authentication.
    • Prevent physical manipulation of the EtherCAT network.
    • Independently establish conformity with the EU Cyber Resilience Act (CRA).
