He obviously meant copy and pasting the design. What did you think he meant?

I have no idea - that's why I was asking. I've been responsible for installing systems that had the same "design" into multiple physical locations - hundreds of physical devices at each location.

Having a common design does help but it doesn't help that much as most of the problems are with the physical realities of each location - and what I did was much simpler and less critical than signalling.
