Abstract: An industrial controller can perform multi-dimensional optimization locally using the controller's native hardware and processing. An optimization algorithm is encoded on the industrial controller in a language understandable and executable by the controller (e.g., IEC61131-3). The optimization algorithm is adapted for the scan-based processing performed by industrial controllers rather than sequential processing, thereby allowing the optimization algorithm to be executed by the industrial controller as part of the controller's control program execution. A control program development system allows a user to add and configure the optimization algorithm as an instruction within the controller's control program. The instruction's configurable parameters allow the user to submit constraints and cost functions for the algorithm.

Abstract: A bag rack, method and system for reducing the time needed to open a bag and have it ready for use at a checkout terminal or other station where the time required to opening a bag is critical. The rack allows a bag to be opened with one hand using a single upward and forward motion.
