
Name Server 2: IP address of the secondary name server, which is used when the primary name
server is not available, or it is unable to resolve a host name.

Domain Name: The default domain name is used when resolving host names that are not fully
qualified. For example, if the default domain name is “odva.org”, and the device needs to resolve a
host name of “plc”, then the device will attempt to resolve the host name as “plc.odva.org”.
Attribute 6, Host Name
This attribute contains the host name of the encoder.
Attribute 8, TTL Value
It is the value the device shall use for the IP header Time-to-Live field when sending EtherNet/IP packets via
IP multicast. All values between 1 and 255 are accepted.
Attribute 9, Multicast Configuration
This attribute contains the configuration of the device’s IP multicast addresses to be used for EtherNet/IP
multicast packets. There are 3 elements in this data structure:

IP Multicast Addresses Allocation Control
= 0

Multicast addresses shall be generated using the default allocation algorithm.
= 1

Multicast addresses shall be allocated according to the values specified in the parameters

Number of IP multicast addresses

Stating multicast IP address
Attribute 10, Enable ACD (Address Conflict Detection)
This attribute enables (1) or disables (0) the address conflict detection activity.
Attribute 11, Last Conflict Detected
When the ACD function is active, this attribute provides information on the last address conflict detected.
Attribute 13, Encapsulation Inactivity Timeout
This attribute is used to enable TCP socket or DTLS session cleanup (closing) when the defined number of
seconds (default is 120) have elapsed with no Encapsulation activity.
