  Key Concepts: 
  Last Will is a feature of the MFG-PCO Plant Connectivity component of SAP that allows users to define a set of actions that will be triggered when a device disconnects from the system. This feature is useful for ensuring that any changes made to the system are properly saved and that any necessary clean-up tasks are completed. 
  
  How to use it: 
  To use Last Will, users must first define the actions they want to be triggered when a device disconnects. This can include saving any changes made to the system, closing any open files, and performing any other necessary clean-up tasks. Once these actions have been defined, they can be associated with a specific device or group of devices. When the device or group of devices disconnects from the system, the Last Will feature will automatically trigger the defined actions. 
  
  Tips & Tricks: 
  When defining Last Will actions, it is important to consider what tasks need to be completed in order to ensure that the system remains in a consistent state. Additionally, it is important to ensure that all Last Will actions are properly tested before they are associated with a device or group of devices.
