- | Subnetworks are smaller ME systems inside larger ones. | + | A **subnetwork** is a loosely-defined term in Applied Energistics 2, but it generally refers to any smaller ME system that supports your main network or handles a specific task. They are typically small enough to not require controllers. |

+ | ===== Why Use Subnetworks ===== | ||
+ | |||
+ | * **Restricting Access** – Prevent certain devices from accessing your main storage. For example, an import bus on a pipe subnet should not have access to your main cells, or it will dump items into them instead of the destination inventory. | ||
+ | * **Saving Channels** – Reduce channel usage on your main network. For example, a single Pattern Provider can output to an Interface connected to several Storage Buses on multiple machines, using 1 channel instead of one per machine. | ||
+ | |||
+ | Colored cables have nothing to do with subnetworks except that different colors prevent cables from connecting to each other. | ||

+ | ===== Common Subnetwork Uses ===== | ||
+ | |||
+ | * **Item/ | ||
+ | * **Filtered Breaking** – Annihilation Plane connected only to a Storage Bus, ensuring the plane can only place items into a specific inventory. | ||
+ | * **World Placement** – Interface feeding a Formation Plane, so whatever enters the Interface is placed or dropped into the world. | ||
+ | * **Automation** – Controlled setups like automatically creating Certus Quartz, regulated with an ME Level Emitter on the main network. | ||
+ | * **Specialized Storage** – A farm output system isolated via a Storage Bus on an Interface, preventing farm overflow from filling main storage. | ||

+ | ===== Powering Subnetworks ===== | ||
+ | |||
+ | A very useful tool is the **Quartz Fiber**. | ||
+ | It transfers power between networks **without connecting them**, allowing you to power subnetworks without needing extra Energy Acceptors or power cables everywhere. | ||
- | * Useful for automation loops. | ||
- | * Storage Bus or Interface bridges connect them. | ||
- | * Keeps recipes and devices isolated while still sharing items. | ||
