Included OPC Test Client Eases Testing to Ensure Your Setup Works

Use the OPC Quick Client as a testing tool

The OPC Quick Client allows you to perform OPC DA read and write operations on the TOP Server at the Server, Group and Item level. This allows you to test out the functionality of the TOP Server prior to configuring your final HMI, SCADA, Historian, MES and other programs that will ultimately interface with the TOP Server.

OPC Quick Client Performance Tests

Performance tests in the OPC Quick Client measure the amount of time it takes to execute a specified operation for each item configured in the OPC Quick Client.  You can define the number of times to perform the test or a maximum duration for the test, after which the results will be displayed, providing the average time, maximum time and minimum time per iteration and the number of times the test was performed.

Precise testing with ability to launch from Channel, Device or Tag Group

Starting with TOP Server V6.13, you can now launch the OPC Quick Client as a right-click menu option for any Channel, Device or Tag Group in your TOP Server Configuration. Why is this important?

For many years, it's been possible to launch the OPC Quick Client from the TOP Server toolbar, automatically subscribing to all configured static tags and systems for all configured Channels, Devices and Tag Groups in the TOP Server project. Which has always been convenient but for large projects, that can be a lot of tags that can impact normal communications for your HMI, SCADA or other client, depending on the configured default update rate.

Now, you can more precisely choose which Channel, Device or Tag Group you're interested in testing and the OPC Quick Client will only automatically subscribe to those specific static tags and system tags under the selected branch.
