Abstract: An embedded processing system includes processing circuitry, a memory system, and a plurality of attached modular components. The attached modular components are each provided with a nameplate including at least part and serial number data. The processing circuitry is operable to receive the nameplate information from each of the attached modular components and compare the received nameplate information with stored nameplate information for the particular attached modular component. The processing circuitry is operable to communicate with the attached modular component if the received nameplate information matches the stored nameplate information and identify a fault if the received nameplate information conflicts with the stored nameplate information. A method and an assembly are also disclosed.

Abstract: An embedded processing system and access combination includes processing circuitry, a memory system, and a plurality of user credential files. The user credential files include an encrypted user identifier, and an encrypted list of authorized task roles the particular user would have within the embedded processing system. Expected credentials from the user credential files are stored in the memory system. The processing system is programmed to receive a user credential file from a user, and compare expected credentials within the memory system to identify if the user is an authorized user. The processing system is programmed to allow access to an authorized user and deny access to an unauthorized user and determine what task roles are authorized for the authorized user, and deny access for the authorized user to other tasks. A method and an assembly are also disclosed.
