Instance Attribute "Configuration Control"
This attribute allows control of the TCP/IP network interface configuration.
When using the Configuration Control attribute, the device can be configured to use statically
assigned IP values or DHCP. If the value is changed from DHCP to statically assigned, the device will
continue using the current IP address. When changing from statically assigned to DHCP, the drive
will try to get an IP address from the DHCP server. If this fails, the communication with the drive
cannot be re-opened and you must set the IP address manually from the panel or enable the DHCP
server in the network.
Changing the Configuration Control is not allowed if the I/O connection is open.

If the "IP Address Mode" panel parameter is "Fixed IP", the value of the Configuration Control is 0.
If the "IP Address Mode" is "DHCP", the value of the Configuration Control is 2.
Features BOOTP and DNS are not supported.
Instance Attribute "Physical Link Object"
This attribute identifies the object which is associated with the underlying physical communications
interface (in the case of Ethernet, for example, the IEEE 802.3 interface). The attribute consists of
two components; a Path Size, which reveals the number of UINT values in the path, and the Path
itself.
The path points to an instance of the EtherNet Link Object. The value of the Path Size is 2 (total of
four octets) and the value of the Path is 20
