Codex Processing Plant Modules
Plants with process lanes have no upgrade slots like single machines. Instead their controller has one module slot for Plant Speed Modules: each module makes every lane of the plant twice as fast, at twice the power, so a run costs the same energy as before.
- Chemical Plant: every column.
- Assembly Complex: every station, also pattern crafts and step recipes.
- Particle Facility: every run; the beam draws the factor in power as well.
- Quantum Facility: the recipe runs, not the coherence field.
- Matter Reconstructor: the reconstruction runs, not the pattern scan.
The Tunnel Furnace, the Foundry, the Agricultural Facility and the Deep Core Extractor take no modules; they scale with their size or their own settings.
| Modules | Speed | Power per tick | Energy per run |
|---|---|---|---|
| 0 | ×1 | ×1 | the same |
| 1 | ×2 | ×2 | the same |
| 2 | ×4 | ×4 | the same |
| 3 | ×8 | ×8 | the same |
- At most 3 modules work; a stack holds no more.
- The factor applies to every run a lane starts after you insert the modules. A run already going keeps its speed until it ends.
- The plant's energy buffer grows by the same factor, so it can always take one tick of its fastest runs. Taking modules out never deletes stored energy: the buffer only shrinks once its content fits.
- The line under the module slot shows the factor, for example "x4".
Compare a 
Speed Upgrade in a single machine: it halves the time too, but for 2.8 times the power, so every run costs 1.4 times the energy. Plant modules have no such surcharge.
Important
Power for the modules Three modules make a plant draw eight times the power while it runs. Its Energy Input Hatches must let that in: plan a hatch tier or two higher, or more hatches, before you insert modules.
Plant Speed Modules are made in the Quantum Facility from two Speed Upgrades, a 
Quantum Processor, a 
Field Emitter and eight 
Superconductor Wire.
Pipes can put modules into the module slot through an Item Input Port of the plant; they cannot take them out.
Tip
Speed or a second plant? Modules give the same output per energy as a second plant, without the second building. They pay off when your power supply is big but your space or your inputs are short.
