Cross Subnet Discovery - Elatec TCP3 3.0.3.1 Technical Manual

4. Discovering TCP3 Devices on the network
send that updated configuration back to the same converter to multiple converters.
Double click on the TCP3 Config application which will then start and the window shown below will
open.

Once the TCP3 Config tool is started, it will immediately begin to broadcast a discovery message to each
specific IP address on the same subnet as the workstation on which TCP3 Config is running. It will only
send one message to each address and will then listen for a response to that message from each device.
All of the TCP3's connected to the local subnet, will appear once discovered. They will be presented in
the order they respond to the discovery message sent from the TCP3 Config tool. This can take up to 60
seconds. If the host PC on which TCP3Config is running is connected to multiple networks for example
a wired and a wireless connection, TCP3Config will search both networks for converters. This will extend
the search time if each connection is on a different subnet.
Figure 4.3.: Repeat Search For Converters
Any additional devices connected to the network after TCP3 Config completes its search will not be auto-
matically discovered. The "Search for Devices" button in the upper right corner of Figure 4.3 will need to
be selected again to repeat the search process.

4.3. Cross Subnet Discovery

TCP3 Config can be enabled to discover TCP3 units on subnets other than the one to which the user's
workstation is connected. The network routers and switches must be enabled to allow web service traf-
