ctrlX Data Layer Client Subscription

Introduction

The code shows how in Python the values of the ctrlX Data Layer are subscribed. Code snippets can be used in your own Python app.

Function Description

The app uses a single node and a multi node subscription.

First the single node subscription is started. It will be stopped after a short period of time.

Then the multi node subscription is started. It will run until a connection break to the ctrlX Data Layer is detected. In this case the app unsubscribes the multi node subscription and ends. The app is restarted automatically by snapd.

Implementation Description

main.py is the single module. It has following tasks:

  • Create a ctrlX Data Layer client connection
  • Subscribe/unsubscribe a ctrlX Data Layer single node subscription
  • Subscribe/unsubscribe a ctrlX Data Layer multi node subscription
  • Close app on ctrlX Data Layer client connection break
