getting coordinate based on survey point from dynamo

hi guys I am new to dynamo, I want to get coordinates point for embedded plates, because i want the coordinates to be in schedule i am using dynamo to extract the coordinates and place them in shared parameter i created, I was able to create a script but the coordinates is based on internal origin, the project I am working on has real world data and we are using shared coordinates for survey point, the question is how to convert the coordinates from internal origin to survey point in dynamo, I tried different ideas but didn't work.
