Abstract: An electric heat trace (EHT) control system and corresponding methods are provided. The system comprises a heat trace cable to heat a surface, a sensor that outputs a status value, and an EHT controller in communication with the heat trace cable and the sensor. The EHT controller receives the status value from the sensor, compares the status value to a first threshold, and outputs the status value and a first alarm flag when the status value meets the first threshold. The system further comprises a gateway in communication with the EHT controller. The gateway receives the output status value and the first alarm flag when output from the EHT controller, compares the status value to a second threshold, and communicates a second alarm flag to a management system in communication with the gateway when the status value meets the second threshold.

Abstract: Disclosed herein is a data processing system-implemented method, a data processing system, and an article of manufacture for investigating computer software. The data processing system-implemented method includes capturing tracing information at one or more boundary points of the computer software, and reproducing a behavior of the computer software at the boundary points based on the captured tracing information.
