This lesson is intended for a very small group of people are not allowed to manually configure their IP address and whose network policy does not allow their PLC trainer to be on their network.

Important steps before you continue:  This will only work on an isolated network with your PC, PLC and other training related Ethernet devices.

5.  If this is your first time opening it then you will need to configure your network settings.  Enter a Subnet of 255.255.255.0.  The others can stay at their default value.

6.  Unplug the Ethernet cable from your PC, wait a few seconds, then plug it back in.  You should see a new entry in the "Discovery History" section.  Look at the Ethernet Address (MAC) for the new entry and make sure the value shown in the area circled in Yellow matches the Physical Address shown in Step 3.  If they match, highlight the line show it turns blue then click the "Add Relation" button circled in yellow.

7.   Make sure the Ethernet Address circled in yellow matches the Physical Address found in step 3 then enter the IP address you want your PC to be in the IP field.  To continue with your lessons, 192.168.1.123 will work.  Click the "OK" button.

11.  Type "ipconfig" and press enter.  You should now see an IPv4 Address of 192.168.1.123 and a Subnet Mask of 255.255.255.0 for that connection.  If you don't see the correct subnet then check the Network Config of the BOOTP-DHCP Tool, make sure the subnet is properly entered, and try again.
