Site adaptation
Layers
The platform layer is the same at every site. Device differences live in the site adaptation layer. A point table is the configuration and measurement points for one device at one site. One device is one process and one Windows service.
Driver validates commands, writes them, and reads them back. DataTS writes field points into the time-series store. The two do not call each other.
VirtualPlant
VirtualPlant is the virtual plant used for integration. That closed loop does not go through a field Driver. VirtualPlant writes the time-series store itself. Do not expect a second DataTS process to write the same paths.
