Abstract
Official abstract text for this publication.
A system includes an industrial controller having a memory and a processor configured to operate the industrial controller in an open mode, wherein the open mode is configured to enable the industrial controller to receive instructions via unauthenticated network connection or a local connection. The processor of the industrial controller is further configured to operate the industrial controller in a secure mode, wherein the secure mode is configured to enable the industrial controller to receive instructions only via an authenticated network connection.
First claim
Opening claim text (preview).
