Project Cybersyn

Train Limits

Cybersyn reads the vanilla train limit and adheres to it allowing you to use it as you would normally in Factorio with basically no difference.

Behold one of the most feature-rich and performant train logistics network mods Factorio has to offer. Named for Project Cybersyn of Allende's Chile, with just this mod you can coordinate the economic inputs and outputs of your entire megabase. Similar in functionality to the famous Logistics Train Network mod, but with a much broader scope.

Quick Start Guide for Factorio 2.0 version

This mod is constantly being worked on and as we add more features and make changes to existing ones description below may no longer accuratly represent current state of the mod. Its best to follow the project's wiki page. You can still follow below description as main concepts remained the same and only fill new stuff from the wiki if that form of presentation is more suited for you.

Quick Start Guide for Factorio 1.1 version

Within Project Cybersyn, you can think of requester stations as requester chests, provider stations as passive provider chests, depots as roboports and trains as the logistics bots. There is a direct correspondence between the Cybersyn train network and Factorio's robot logistics network.

A bare minimum Cybersyn train network consists of 2 components: depots and stations. Both are created by placing a cybernetic combinator adjacent to a train stop. Select the "Mode" of the combinator to "Station" to create a station, and to "Depot" to create a depot. Create a basic train and order it to park at the depot you just created, it is now controlled by the Cybersyn network. Depots and stations can have any train stop name, names do not impact their function. The circuit network input of a station's cybernetic combinator determines what cargo, as in items or fluids, that station will request or provide to the Cybersyn network. A positive cargo signal is interpreted as that station providing that cargo to the network; A negative cargo signal is interpreted as that station requesting that cargo from the network.

To make a basic provider station, create a cargo buffer of chests or tanks adjacent to the station's tracks, and connect that buffer by wire to the input of the cybernetic combinator. To make a basic requester station, repeat the same, except reverse the direction of the inserters or pumps so they are unloading instead of loading; then connect a constant combinator to the same circuit network, set it to output the number of cargo you want this requester station to keep loaded in its cargo buffer, and flip the sign of each so the signal strength is negative. Then add the signal called "Request threshold" to the constant combinator. Set its signal strength to be at most the cargo capacity of the trains in your system. Once the provider station contains the cargo being requested, a train will automatically be sent to deliver that cargo from the provider station to the requester station. The requester station's buffer will automatically be topped up on the cargo being requested. Be sure that the requester station has the space to at minimum unload 2 fully loaded trains.

Follow the above directions and you have set up a bare minimum Cybersyn network! You may continue adding onto it with more stations and depots and Cybersyn will automatically manage all of them for you. There is one issue with this kind of network though; trains won't always deliver full loads of cargo, meaning trains will make deliveries more frequently than is necessary. To fix this issue you will need to start using "request thresholds". To get a full picture of how request thresholds work, either import the official example blueprints from above, or read the Request thresholds section below.

Features

Minimalistic and intuitively designed, without sacrificing features. Configure your stations using just 3 virtual signals, a couple of combinator settings and the train stop's own train limit.

A whole suite of new and optional circuit network inputs and outputs to control your stations precisely

• Natively read out all deliveries currently in progress for a station, not just the loading or unloading orders of the parked train.
• Set request thresholds per cargo instead of just for the entire station.
• Read out cargo loading or unloading orders per train wagon, instead of just for the entire train.
• Set item filters per cargo wagon, making multi-item deliveries very easy.
  

These all combine to make it possible to create "universal" stations; stations that provide any arbitrary number of different items for a train of any arbitrary length! Build stations that supply you all items from your mall, stations that grab selected items from your disorganized storage chests, or stations that transfer any item between two otherwise completely distinct networks!

Stations can automatically build allow-lists for trains they can load or unload. Inserters or pumps adjacent to the station's tracks are auto-detected. No more deadlocks caused by trains mistakenly attempting to fulfill a delivery to a station that cannot unload it. This feature is compatible with miniloaders.

Trains can automatically visit centralized refuelers. It is not required that every single depot loads trains with fuel.

Trains can bypass visiting the depot if they have enough fuel. Trains spend far more time productively making deliveries rather than travelling to and from their depot. Fewer reserve trains are needed as a result.

Easy and versatile ways to define separate train networks. Bitwise network masks are now optional! Networks are identified by signal id first, then by signal strength.

Improved fault handling. Mistakes and misconfigured stations are unlikely to result in cargo being delivered to places they shouldn't, and the player will be alerted immediately about the fault.

Runs a custom, highly optimized central planning algorithm, resulting in exceptionally good performance, see https://forums.factorio.com/viewtopic.php?p=580024#p580024. This allows the station update rate to be twice that of LTN by default, resulting in more responsive dispatching, especially on larger bases.

Native space exploration compatibility! Without any trouble this mod will automatically detect any space elevator on the planet and add it to the orders of trains which want to travel between surfaces. Unless there is a space elevator connecting the surfaces, each surface must be set to its own network.

Mod Details

This mod adds a single new entity to the game, the cybernetic combinator. This combinator can be in one of 5 different possible modes. While each mode has a purpose, the only modes you are required to use are station mode and depot mode.

Station mode

When placed adjacent to a vanilla train stop, a Cybersyn station is created. This station can provide or request cargo to your train network. Connect the input of the combinator to a circuit network; When a positive cargo signal is received, this station will provide that cargo to the network, when a negative signal is received, this station will request that cargo from the network. When a station is providing a type of cargo that another station is requesting, a train order will automatically be generated to transfer that cargo from the providing station to the requesting station. When a train arrives to fulfill this order, the output of the combinator will give the full list of cargo expected to be loaded (negative) or unloaded (positive) from the train.

Stations can automatically build allow-lists. When this option is enabled, only trains that can be loaded or unloaded by this station will be allowed to make deliveries to it. Stations determine this based on what inserters or pumps are present at this station along its tracks. When disab
