Note –

Setting Primary Host to 0.0.0.0 allows the controller to publish Sparkplug B data without waiting for a Primary Host Application to report ONLINE. This requires Cscape 10.3 or later.
Enter exactly 0.0.0.0. A blank field or any other value is treated as a normal Primary Host ID. Use this option only when no Primary Host Application is used.
Primary Host = 0.0.0.0; The controller skips the Primary Host check and publishes NBIRTH and NDATA as soon as it connects to the MQTT broker. STATE messages are ignored.
