Controller for providing uninterrupted control of a node in a lighting network and a method thereof

A method for providing uninterrupted control of a node via a segment controller;

• wherein the node is comprised in a lighting network:
• wherein the method comprises:
• executing a plurality of logical instances of a control application on the segment controller;
• detecting a malicious signal indicative of an unauthorized access request to the segment controller;
• determining that a logical instance which currently controls the node has been affected by the unauthorized access request;
• determining a logical instance, of the plurality of logical instances, which is unaffected by the unauthorized access request;
• switching the logical instance of the segment controller which controls the node from the affected logical instance to the unaffected logical instance;
• and wherein when the malicious signal is detected;
• the lighting network is switched from a normal control mode to a basic lighting control mode;
• wherein in the basic lighting control mode, the determination of an unaffected logical instance, of the plurality of logical instances, is limited to an unaffected logical instances arranged for providing control of the node being a lighting device;
• wherein in the basic control lighting mode, the control of the lighting device is limited to providing functional lighting, which provides the mandatory illumination needed for the daily activities.
