Visual conventions for reading network diagrams in Stationeering Systems

Network topology diagrams show logical power distribution and data connections between systems. These simplified representations focus on functional relationships rather than physical layout.

Reading Network Diagrams

• Hierarchical Flow: Shows power source relationships from generation to consumption

• Color Coding: Represents data network domains (not power flow)

• Mixed Connections: Some devices receive power from one network and send data to another

Power Distribution Elements

Transformers/APCs: Rectangular boxes showing device type and network name

• Standard rectangular outline = Direct power distribution

• Color indicates devices that share a data network domain, not power source

Network Cables: Lines connecting components

• Solid lines = Primary connections

• Color follows the data network domain

• Objects are deduplicated to reduce diagram clutter

• Heavy solid lines recommend using high-wattage cables

Connection Points: Different shapes represent different element types

• Lines represent cables

• Boxes represent transformers and power distribution

• Circles represent device consumers

• Diamonds represent logic components

Device Labeling: Elements show device type and functional identifiers

• Single instances: Device type only

• Multiple instances: Device type + unique identifier describing functional purpose

• Example: Two Logic I/O devices on same network distinguished as "Pressure Sensor" and "Failsafe Control"

Network Classifications:

• MAIN — Operational power networks fed through series transformer-then-APC configuration. Devices connect to MAIN networks for normal operations. The -MAIN suffix indicates the network has a corresponding -ALT alternative path, distinguishing dual-feed redundancy implementations from single-path configurations.

• BKP — Battery backup system for emergency operation and charging isolation. Uses transformers to prevent high-power charging cycles from disrupting precision equipment.

• FS — Failsafe system that automatically shuts down equipment during fault conditions to prevent resource loss or equipment damage.

• LL — Load leveling system that uses a transformer and APC in series to smooth out temporal power mismatches between baseline and peak power demands.
