This read-only enumerated value reports whether the Hirschmann discovery protocol on this device is operating in read-write or read-only mode. Admins check it to determine whether the device will accept configuration changes, like IP address assignment, pushed via the discovery protocol, or only report its status. For example, a value of read-only(2) tells the admin that this device won't accept IP configuration changes through HiDiscovery and must be configured another way.
