Running and Verifying Your IOC

Use a GUI Client

Unified Automation offers a free professional GUI client application for OPC UA, called UAExpert. (Obviously, there are also other tools by other vendors.) Using such a tool is highly recommended for any integration of OPC UA servers.

Start your IOC

Run your IOC is the regular way.

cd iocBoot/iocUaDemoServer
./st.cmd

Hint

Always exit your IOC gracefully using ^D or exit.

Hard exits or killing the IOC process will leave resources in use on the OPC UA server, which will only be cleaned up after a grace period.

Enjoy OPC UA!

Change values (of the “Static” set) from UAExpert or the IOC - via command line pvget/pvput - and see them update/change on the other tool.

Browse the server from UAExpert to find more interesting variables, then create records on the IOC to access them.
