The present application relates to ensuring data consistency between a modular device and an external system. Techniques are described for ensuring data consistency between devices at a control device using configuration signatures. A control device can receive and store a baseline configuration signature for a first modular device. Upon initialization of the first modular device, the control device can receive a current configuration signature from the first modular device. The control device can compare the current configuration signature with the baseline configuration signature and, if a mismatch is found, generate a notification indicating that data subsequently received from the first modular device is of uncertain integrity.

Ensuring data consistency between a modular device and an external system

Embodiments of the disclosure provide for a system and method for determining a circuit breaker position in a power distribution/load center. In one embodiment, the load center includes a plurality of circuit breakers. Each circuit breaker includes a base and a plurality of contact components coupled to the base. In that regard, an activation of a combination of the contact components indicates a position of the circuit breaker within the load center. The activation of the combination indicates that one or more of the contact components is in contact with one or more pegs coupled to the load center. When this occurs, a data transceiver coupled to each of the contact components transmits a data signal. The data signal includes a plurality of data bits, where each data bit indicates whether a corresponding contact component of the combination is activated or not activated.

Load center position-based addressing

Embodiments of the disclosure provide for a fast device installation and replacement (DI&R) service in a network while simultaneously providing confidentiality and integrity protection for sensitive device data. In one embodiment, this protection is provided by using certain characterization data associated with each device in a network to generate a passphrase. This passphrase can be related to the topology of the devices. In one embodiment, the passphrase is a concatenation of certain device characterization data with respect to the topology. In embodiments, the concatenation includes arranging the characterization data based on an order of each device with respect to the topology. Cryptographic keys are derived based on the passphrase. The cryptographic keys are used to automatically encrypt and decrypt the sensitive device data without user intervention. In one embodiment, the cryptographic keys are used to automatically decrypt the sensitive device data to configure a replacement device for the network.
