General

For the very simplest, introductory examples, see this page on our main Web site: Get OPC data into Perl.

Note: We do not regularly update these examples with new versions. You may have to modify the code to use newer versions.

The Perl examples were tested in ActivePerl v5.14.2.

The features decribed or used here are only available if you included "COM development" during the installation of Connectivity Software. If the features are missing, simply re-run the installation program, making sure that "COM development" is included in the selection made on the "Installation Dashboard" setup wizard page.

ReadAndDisplayValue.pl: The simplest console application for OPC “Classic”. Reads and displays an OPC item value.
SubscribeToValue.pl: Subscribes to changes of an OPC Classic item, and displays the values.
UAReadAndDisplayValue.pl: The simplest console application for OPC UA. Reads and displays an OPC item value.
UASubscribeToValue.pl: Subscribes to changes of an OPC UA monitored item, and displays the values.

Where are the examples?

The examples are available in multiple formats and on different locations. You can pick the one that suits you the best.

On Windows, if you have used the Setup Program to install QuickOPC, examples source files are available from the Start menu or the Launcher application.
The examples are in this documentation - shown in articles that describe the related concepts, and also all together: QuickOPC Examples.
