General Deployment Guidelines - ABB LWT300 series User Manual

For cybersecurity reasons, ABB decided not to password protect the HART communication protocol
in LWT series instruments. As such, before implementation, the intended application should be
assessed to ensure that this communication protocol is suitable.

General deployment guidelines

• Limit and control physical access to the device and the network on which it is connected.
• Limit and control access to all HART tools.
• Use role-based access according to needs.
• Change all default passwords and strictly control their dissemination.
• Lock and/or write-protect the instrument whenever possible and/or practical.
• Disable Service access (from the Advanced access level; see "Setting up role-based passwords" on
page 41).
