A Topic Variable is a flexible special OmniServer element that gives you the ability to define a device specific variable such as a Device ID at the OmniServer topic level. This effectively makes your OmniServer protocol reusable for those devices using the same protocol, since you can now specify the value of the variable when creating the OmniServer topic instead of creating a protocol for each device with the value hard coded.
In this video blog, I show you how to get the most from your OmniServer by using topic variables with your protocol to reduce your engineering time and effort to create an OmniServer protocol.
Watch this video to learn what OmniServer topic variables are and how to start implementing them for your OmniServer protocol. Miss our video tutorial on using OmniServer Translations? Click Here to get caught up!
Just to summarize, in this video, I've shown you:
- How to configure a topic variable in your OmniServer protocol.
- How to define the topic variable in the actual request/response portion of your command/response message in your OmniServer protocol.
- How to use the topic variable when using your OmniServer protocol in a new OmniServer topic.
