-Niagara has in my opinion 2 primary functions:+Niagara has in my opinion 4 primary functions:
   * First, controlling output and input points (IO), which in turn can control all kind of actuators, motors or sensors.   * First, controlling output and input points (IO), which in turn can control all kind of actuators, motors or sensors.
   * Second, integration of pretty much any network (Driver) or system you can imagine. My personal favorites being Bacnet, Modbus. But can also do more exotic things like MQTT.   * Second, integration of pretty much any network (Driver) or system you can imagine. My personal favorites being Bacnet, Modbus.

 +==== System overview ====
 +
 +A typical office customer setup would be comprised of the following:
 +
 +  * Supervisor (PC or Controller)
 +  * Main controllers (1 pr floor typically)
 +  * IO Room controllers connected to main controllers (1 pr 1-2 room)
 +  * Airhandling unit with integrated controller connected to supervisor or main controller
 +  * Airhandling unit with direct IO controllers from a main controller or dedicated controller.
 +  * Any integration from light or other, connected to main controller or supervisor.
 +
 +All network connections is preferred to be TCP/IP but serial 2 wire connections is widely used too.
 +
 +Best practice is to keep as much programming and calendars as local as possible. Meaning, if you can keep a 0 point supervisor, it's preferred.
 +Also, direct signal transfer from controller to controller is preferred.
 +This way, if supervisor restarts, controllers keep running their programs.
 +
 +The supervisor is then used for collecting alarms, history data and proxy points from controllers, to present on a website.

 +
 +==== Framework breakdown ====
 +
 +Framework runs as a 2 part deal, a platform and a station.
 +
 +=== Platform ===
 +The platform is running either on a unix based controller or windows based PC, and can best be compared to "a firmware".
 +It contains settings for TCP/IP and licensing.
 +It also contains systems to copy stations and control start/stop of these.
 +
 +== Platform tree structure example ==
 +See below image of a standard platform setup
 +{{ :c_niagara:pasted:20220225-214956.png |}}
 +
 +=== Station ===
 +
 +It's where all the magic happens!
 +It it build up like a tree structure.
 +First comes 
 +
 +  * Alarms
 +  * Config
 +  * Files
 +  * Hierarchy
 +  * History
 +
 +== Alarms ==
 +Shortcut to alarm section, with views and database maintenance.
 +
 +== Config ==
 +Where all primary programming is located, it also contains Services, Drivers and Apps.
 +
 +  Services
 +  Contains alarm handling, user services, web and the internally used fox servers 
 +  and other primary backend systems. 
 +  If you want a primary function to work, this is where to locate and install it.
 +
 +  Drivers
 +  Contains programming part of the station, including Bacnet and Modbus drivers, 
 +  but this is also where you create your programming, 
 +  in separate folders or directly inside the drivers network.
 +  A folder contains multiple view options like property sheet or wire sheet.
 +  They also supports a custom view (Px view), meaning to show website animations.
 +
 +  Apps
 +  I actually don't know what this is for?
 +
 +== Files ==
 +Is the local file storage, it contains images, px files (website animations) or other files used.
 +
 +== Hierarchy ==
 +One of the newer functions, used to dynamically build a tree structure for your site, and to allow easier navigation.
 +In my opinion it's not "completely there yet" and I look forward to new updates and features for this part.
 +The hierarchy is build using tags on folders and points, they can be direct or implied.
 +What is needed to make it really nice is implied relations and better interaction with objects.
 +
 +== History ==
 +Contains all your history files and the ability to run database maintenance.
 +
 +== Station tree structure example ==
