Connect OPC UA Client to OPC UA Server

Once the OPC UA server is running, a client can connect to the server and browse the address space. The OPC
UA server uses the OPC UA Binary protocol to communicate with the client. The OPC UA Binary connection
strings take the base form displayed below.
As an example, a connection string for the OPC UA server is constructed. To begin, the controller TCP/IP
address of the embedded Ethernet port is needed. One method to find this information is to use the Machine
Edition programmer. Open the controller's project and select the project top level in the Project tab of the
Navigator window. From the Inspector window, scroll down to the IP Address Entry (see the screenshot
below). From the figure, we can see the current IP address is 10.10.1.102. For this example, the client's
connection string for the controller is the following:
opc.tcp://10.10.1.102:4840
