Abstract: A method for identification and retrieval of data of interest in an OPC UA PubSub automation network, wherein the OPC UA PubSub automation network comprises at least one publisher. The method includes providing publisher data, connecting a gateway device to the OPC UA PubSub automation network, discovering at least one information source in the OPC UA automation network, identifying and connecting to a broker by the gateway device, wherein the broker manages the publisher data provided by the at least one publisher, determining, by the gateway device, at least one matched information source from the discovered at least one information source based on information intent and PubSub meta information provided by the broker, and retrieving, by the gateway device, the data of interest from the at least one matched information source.

Abstract: Disclosed is a method for control loop performance monitoring in a variable frequency drive. A set of data is inputted to one or more control loop performance monitoring algorithms comprised in the variable frequency drive, wherein the set of data comprises at least a measured value of a process variable, a target value for the process variable, a set of controller input parameters, and a controller output. An output from each of the one or more control loop performance monitoring algorithms is obtained based at least partly on the set of data. One or more key performance indicator values indicative of control loop performance are determined based at least partly on the output from each of the one or more control loop performance monitoring algorithms. The set of controller input parameters is adjusted based at least partly on the one or more key performance indicator values.
