Ethernet Communication
2.1

Outline

Ethernet communication is available for the Ethernet model and the safety communication model.
 Precautions for communication
• To maintain the security (confidentiality, integrity, and availability) of the inverter and the system against unauthorized
*1
access, DoS attacks, computer viruses, and other cyberattacks from external devices via network, take appropriate
measures such as firewalls, virtual private networks (VPNs), and antivirus solutions. We shall have no responsibility or
liability for any problems involving inverter trouble and system trouble by DoS attacks, unauthorized access, computer
viruses, and other cyberattacks.
• Depending on the network environment, the inverter may not operate as intended due to delays or disconnection in
communication. Carefully consider what type of environment the inverter will be used in and any safety issues related to
its use.
*1 DoS: A denial-of-service (DoS) attack disrupts services by overloading systems or exploiting vulnerabilities, resulting in a denial-of-service (DoS)
state.
 Ethernet communication specifications
The communication specification varies depending on the specification of the master or the communication protocol.
