Silo

Vanilla game class at Assets.Scripts.Objects.Chutes.Silo. Bulk item storage that sits on a chute network and accepts stacked items (ore, ingots, etc.). Minimal logic surface: exposes its current item count and nothing else.

Class hierarchy

// Assembly-CSharp.dll :: Assets.Scripts.Objects.Chutes.Silo
public class Silo : DeviceImportExport { ... }

Chain: Silo -> DeviceImportExport -> DeviceImport -> Device.

Logic variables

// Silo.CanLogicRead
public override bool CanLogicRead(LogicType logicType)
{
    if (logicType == LogicType.Quantity)
    {
        return true;
    }
    return base.CanLogicRead(logicType);
}

// Silo.GetLogicValue
public override double GetLogicValue(LogicType logicType)
{
    if (logicType == LogicType.Quantity)
    {
        return SiloThingQuantity;
    }
    return base.GetLogicValue(logicType);
}

LogicType	Read	Write	Value
Quantity	yes	no	current stored item count, 0..600
Ratio	no	no	NOT exposed, do not use
Maximum	no	no	NOT exposed, capacity is implicit
Setting	no	no	NOT exposed
(inherited)			On, Power, Error from base

LogicType.Ratio is a common fill-indicator on other Stationeers devices (sorters, furnaces, tanks), but the Silo class deliberately does not implement it. Any IC10 script using lb <silo> Ratio Average will fail to read. Scripts needing a fill percentage must compute it themselves from Quantity and the fixed capacity.

Capacity

MaxItems = 600 is hardcoded in the class. A full silo reports Quantity = 600; an empty silo reports Quantity = 0. There is no logic-readable way to query the max; it must be encoded as a constant in consuming scripts (or derived from stationpedia at design time).

Typical IC10 pattern

Absolute-threshold gating is simpler than computing a ratio:

define Silo HASH("StructureSilo")
define SILO_FULL 600                 # MaxItems from the decompile
define SILO_EMPTY 0

lb r1 Silo Quantity Average          # read current item count
sge r2 r1 SILO_FULL                  # 1 if silo is at capacity
sle r3 r1 SILO_EMPTY                 # 1 if silo is drained

If a ratio is genuinely needed (for display, etc.), div r1 r1 600 after the lb produces a float 0.0..1.0, with no division-by-zero concern because 600 is a constant.

Verification history

• 2026-04-20: page created. Decompile pass against Assets.Scripts.Objects.Chutes.Silo; only readable LogicType is Quantity, capacity is hardcoded at MaxItems = 600.

Open questions

• Whether StructureSilo is the correct prefab name for HASH(). The decompile shows the class name is Silo; Stationeers convention prefixes Structure on the prefab name for built structures, but this was not verified against a PrefabName string in the decompile. Confirmable via configuration tablet against a placed silo.
• Community references to "SDB silo" (Silo Dense Bulk) may denote a modded variant rather than vanilla Silo. A modded silo would have its own prefab hash and its own LogicType surface; the vanilla analysis above may not apply.
