An  oscillography  is  started  when  the  "fault  init"  state  is  activated;  this  is  a  configurable  logical 
signal. The default configuration is as follows: 

 

 

 

 

It is possible to visualize the oscillography using SICom software 

  

 

 

Using SICom software, it is possible to save the oscillo as a COMTRADE file
