Abstract
A method for dynamic load balancing between nodes in a network centric process control system. The network centric process control system includes a plurality of nodes and each node includes control service components, where each control service component is a separate executable running in a separate operating system process as provided by a real time operating system of each node. The method is performed by a node manager of a node, and the method includes negotiating a load balancing master role between the plurality of nodes, wherein the negotiating is based on an indication of the plurality of nodes representing load balancing cluster nodes, subscribing, in the negotiated load balancing master role, to a load balancing information from nodes of the load balancing cluster nodes, and reallocating, in the negotiated load balancing master role, one or more control logic tasks from one node to another node of the plurality of nodes based on the subscribed load balancing information. A node manager, a computer program, and a computer program product thereof are also presented.
