Techniques to facilitate feature licensing of industrial devices employed in an industrial automation environment are disclosed herein. In at least one implementation, a security certificate for an industrial device is provisioned based on a first private key associated with the industrial device, wherein the first private key is securely stored in a hardware root of trust within the industrial device. A device information package for the industrial device is generated based on the security certificate, wherein the device information package is encrypted with a first public key paired with the first private key and signed by a certificate authority using a second private key. The device information package is provided to the industrial device, wherein the industrial device is configured to validate the device information package using a second public key paired with the second private key and decrypt the device information package with the first private key.

Cryptographic feature licensing

Electrostatic charge grounding is achieved by connecting an outer surface touchscreen conductive coating to a grounded conductor in a graphics terminal using an electrostatic charge routing system that provides a path for electrons that accumulate on the conductive coating to pass through one or more non-conductive elements in the graphics terminal. The grounded conductor can be a bezel made of metal or another conductor, a conductive paint layer applied to a bezel or other graphics terminal element, a metal spline pin or a metal screw. The electron path defined by the electrostatic charge routing system can include conductive and dissipative elements such as metal spline pins, metal screws, conductive epoxy, conducting plastic elements providing a short, closed electron bridge.
