User Story

1. As a process when I want to activate or deactivate an LDevice :

The status of an LNode must now be checked before enabling or disabling an LDevice:

•       If the LNode's COMPAS-LNodeStatus is "on". 
  

•       If the LNode has COMPAS-LNodeStatus "off
  

Acceptance criteria

• Check that the process uses COMPAS-LNodeStatus data when activating an LDevice.
