Summary
P-Net before 1.0.4 copies the IP suite of a DCP Set request to the current and the non-volatile configuration, and starts saving it, before the state of the device is checked. If the request is refused, for example because an Application Relationship is active, the configuration is not restored and is still saved. After a restart the device uses the refused address, and may not answer the controller or may use its address. A host with ADJACENT network access can use this while an Application Relationship is active.
