Model
A Category:Model implement the concrete logic and interface to the database.
Example
- Ratio of 2 child channels
Channel type
The channel type is based on a model and describes use cases and attributes.
Example
(based on Ratio)
- Ratio calculator calculates the raw ratio of 2 child channels
- Percentage calculator multiplies the raw ratio of 2 child channels by 100 to get %
Channel
A channel is a concrete instance of a channel type.
Example
(based on Percentage calculator)
- Performance ratio of an inverter
- Disk usage of a server
- ...
Channel hierarchy
The channel hierarchy organizes all channels and links them together.
Here you define for calculated channels the child channel(s) where the data to use come from.
Example
- Performance ratio of an inverter
- Pac AC Power
- Pdc DC Power
