Abstract: This disclosure relates to a method and apparatuses for detecting and reporting suspected tampering of an energy meter to a utility. The method and apparatus uses a plurality of sensors to obtain data relating to one or more input parameters based on the type of input signal. The input parameters are mapped with a tamper type to provide a classification of one or more output parameters. The output parameters are compared to one or more operating conditions of the energy meter to identify one or more suspected tampers. Any suspected tampers are reported to the utility.

Abstract: Energy usage of a plurality of appliances is measured using a single meter. A pattern of energy usage with respect to the plurality of appliances is determined dependent upon the measured energy usage, appliance details of the plurality of appliances, and usage hours of the plurality of appliances. The pattern is provided to a user of the appliances.

Abstract: A process control system includes a process controller level including at least one process controller, and an input/output (I/O) module level including at least one I/O module. The process controller level and the I/O module level are communicatively coupled. and each include control logic comprising control hardware or algorithm blocks. The control logic in the process controller level and the I/O module level are configured to execute and exchange data to perform process control for a process run by the process control system in a distributed fashion across the process controller level and the I/O module level.

Abstract: An apparatus includes multiple circuit paths configured to generate multiple electrical signals to be used to communicate with multiple devices. Each of the circuit paths is configured to use electrical energy from a different one of multiple independent power supplies. The apparatus also includes an I/O terminal configured to be coupled to a common electrical conductor that is coupled to the multiple devices. The I/O terminal is configured to pass the electrical signals to the common electrical conductor. The apparatus is configured to use each of the electrical signals to one of: receive input data from one of the multiple devices or provide output data to one of the multiple devices.

Abstract: A redundancy termination panel includes first and second interfaces configured to be coupled to first and second I/O modules, respectively. The redundancy termination panel also includes a third interface configured to be coupled to a field device. The redundancy termination panel further includes an I/O channel circuit associated with an I/O channel between the I/O modules and the field device. The I/O channel circuit is configured to allow an input current used for receiving data from the field device to be split such that different portions of the input current are sourced by different ones of the I/O modules. The I/O channel circuit is also configured to combine multiple currents driven by different ones of the I/O modules and provide an output current used for sending data to the field device.

Abstract: A method includes receiving, at a first processing device of an input/output module (IOM), new firmware data for the IOM. The method also includes sending an output hold command from the first processing device to a second processing device of the IOM. The method further includes upgrading firmware of the IOM with the new firmware data using the first processing device and attempting a reboot of the first processing device. In addition, the method includes, in response to the output hold command and during the upgrading of the firmware and the rebooting of the first processing device, using the second processing device to cause a field circuit of the IOM to hold at least one previous output signal for one or more external devices.

Abstract: Methods and systems for access control involve dynamically controlling an access to firmware running a certified feature in an energy meter and a non-certified feature in the energy meter. The access can be based on a bifurcation between the certified feature and the non-certified feature running in the energy meter on one or more of a single microcontroller or a group of different microcontrollers.

Abstract: A method and system for detecting tampering of an energy meter can involve, in a first phase: gathering magnetic field sample data, an average magnetic field strength, a minimum magnetic field strength, and a maximum magnetic field strength from a magnetic field condition applied to an energy meter by a magnetic sensor that measures a magnetic field in one or more directions, and using learning coefficients calculated from the magnetic field sample data and the average magnetic field strength, the minimum magnetic field strength, and the maximum magnetic field strength to classify with a classifier, magnet tampering conditions with respect to the energy meter. In a second phase, a magnet tamper event can be identified with respect to the energy meter when the magnet tampering condition classified by the classifier is greater than a magnetic detection threshold.
