Risk Mitigation and Secure Deployment
The idea is to create defence-in-depth protection for each network by allocating firewall solutions to the front of
internal trusted networks of each network by manage firewalls, their configurations and access rules. The
softstarter must be positioned in a trusted network, strictly limited and in a hosted portion of a network or control
system. Configure firewalls according to the principle of denying everything that is not needed nor used. For
secure remote access, use a VPN connection with an encryption layer to create a secure channel over an insecure
network. For more information regarding cyber security and risk mitigation, download the document Cyber
security for ABB drives from the ABB library.
Note: The device uses the default Modbus TCP port 502 (0x01F6). This port must be open in the firewall for
both incoming and outgoing traffic to allow Modbus-TCP compatible devices to communicate.
