4.2 Overview of the engineering
Before you can start using the SPA OPC Server, you need to create and configure an
object tree in the SPA OPC Server configuration tool to define the system structure. The
possible objects are SPA OPC Server, Line, Device, Rack, Module and Signal, see Table
4-1.
The toolbar is placed on top of the screen. The icons for the selectable objects in the
toolbar are colored, and the icons that cannot be selected remain grey.
