Configure Ethernet Settings
1.
Open your Connected Components Workbench project (for example,
Micro820). On the device configuration tree, go to Controller properties.
Click Ethernet.
2.
Under Ethernet, click Internet Protocol.
Configure Internet Protocol (IP) settings. Specify whether to obtain the
IP address automatically using DHCP or manually configure IP address,
subnet mask, and gateway address.
3.
Click the checkbox Detect duplicate IP address to enable detection of
duplicate address.
TIP
The Ethernet port defaults to the following out-of-the box settings:
• DHCP (dynamic IP address)
•
Address Duplicate Detection: On
IMPORTANT
When a DHCP server fails, the Micro800 controller allocates IP
addresses in the private range 169.254.0.1 to 169.254.255.254.
The Micro800 controller verifies its address is unique on the
network using ARP. When the DHCP server is again able to
service requests, the Micro800 controller updates its address
automatically.
