Just an echo of a couple older posts at Inside the System in light of a couple recent questions I received.
There are two posts, of many, that relate to the subject of my post. Who better to get this information from than the proverbial "horse"?
Go with the Flow Part 1 has two videos:
Connectors and Mapping
Connectors and Data
The second post is Go with the Flow Part 2 and has three videos:
Preset and Calculated Flow Configuration
System Flow Configuration
Linking Connectors on Equipment
You can download an example model based on what you've seen in the videos if you like.
