EtherNet/IP
Instance Attribute "Instance Configuration"
This attribute contains the configuration parameters required for a device to operate as a TCP/IP
node. The contents of the attribute depend on how the device has been configured to obtain its IP
parameters (the "Configuration Method" field in the Configuration Control attribute). If the device
uses a static IP address (Configuration Method value is 0), the values in the Interface Configuration
are those statically assigned and stored in the non-volatile memory. If the device uses DHCP (or
BOOTP) (Configuration Method value is 1 or 2), the Interface Configuration values will contain the
configuration obtained through this channel. Until the BOOTP/DHCP reply is received, the values are
0.
Changing the Instance Configuration is not allowed when the I/O connection is open or
Configuration Control-attribute is not set to "statically-assigned".
The IP address, Network Mask and Gateway address consists of four bytes. For example, the IP
address 192.168.0.10 would be in format: C0

Instance Attribute "Host Name"

information purpose.
