Stations & other LTN based designs

[Optera]

"Logistic Provider & Requester for LTN 1.10.13" is to be used with "Logistic Network to LTN stop filter" or a custom wiring of buffer and storage chests.

All other blueprints are designed to only require changes to combinator settings.

omg now i feel a little bit stupid thanks a lot!

Just about to set up my first LTN network in a Krastorio 2 save and I'm struggling to get my head around how to manage air filters, I was hoping to be able to have a single 1-1 train delivering new filters and collecting old ones for recycling. I was hoping to set this up at existing stations rather than set up a separate station at every city block.
So there would be one station that provides clean air filters and unloads the used ones for recycling, and then for example at an ore loading station i'd have 2 chests on the other side of the tracks from the ore loading setup with filter inserters loading/unloading the filters. Is it posible to set this up with LTN?
I'm sure someone must have used a system like this before in K2 but my googlefu seems to be failing me as I can't find any mention of it.

Hi i tryed to do following.
First condition: Train should only come if stations incoming storrage box are free for a hole train (320 stacks must be free 8x40)
(This incoming box is a mixing/multi income box)

Second condition: A !separate! storage schould be ask how many is in and if lnt see its smaler than 250.000 a new train are calling.

Problem, all wat i tested ltn mixed both signals and conditions. So LTN see oh ther are so many space in the storage i bring more trains but the income Box are full.

Is ther a way to seperate the two storage signals?

I hope its clear what i want, i cant explain it verry good sorry for that.
Thx all for answering.

(The green Depotchests are convertet in a red cable, i was to lazy to change all the green to red - so at the circuits the incoming red are the storage magazin down picture)

[FritzHugo3]

I helped me self after days i have this:

Summary:
When the delivery stations at the ore-receiving train stations are full, no trains should arrive, even if the main storage is empty.

Explanation of what the facility is:
A facility to split and sort core ore (bottom left in the picture) and transport it to the mass storage for ores (bottom right in the picture). There are also train stations connected at the top and, not visible here, large cargo ships that also deliver ores on the top left.

If the ore processing facility overproduces certain ores, it stops and blocks the entire production, which is why a completely full storage of a single ore needs to be prevented! This ore is then destroyed (not shown in the picture).

To avoid wasting ores from natural ore fields, I needed the following circuit:

01 First, check how much ore of each raw material is in the main storage.
02 Trains and ships should only deliver in case of emergency when there is insufficient ore processing, and the main storage has fallen below 250.000 of that ore.

03 The delivery box must be empty enough for an incoming train to unload its entire load! (The delivery box can contain different ores at the same time).

After much thought, testing, and experimentation, I have been able to achieve this with the following circuit.

On the left, the input box is asked by a mathematical comparator if it is fuller than 9.000.

This number is composed as follows:
(500 slots from the box * 50 #stack size of ore) = 25.000
(8 wagons * 40 stacks per wagon * 50 #stack size of ore) = 16.000)
25.000 - 16.000 = 9.000

If there are more than 9.000, then output a red signal with a value of 1.

This signal then goes into a second mathematical comparator.
If a red signal with 1 arrives, this number is multiplied by 5.000.000 (this number must be higher than the number with which you want to allow LTN to deliver the resource – in my case, I could also say 250.000, but I prefer millions to make it more universally applicable when copying – so I always make sure it's always too much for LTN and say LTN clearly NO, NO TRAIN!

Then I output the ore as the output signal that could arrive.
Unfortunately, you need to set up a separate mathematical comparator for each commodity that arrives by train at this station (in my case, two below each other).

I added the last mathematical comparator only to prevent feedback with the main storage.
(You don't need this if you place the individual storages separately at different stations. For space reasons, I have all 25 different ores with the same green cable wired together at my place (nickel, tin, aluminum, titanium...), so I need this feedback protection).

I hope the two hours I invested in the pictures, text, and translation will help or inspire someone.

With a system with that much inherent latency the best way would be:
1) count items entering the system
2) subtract items leaving for production
3) send current counter to LTN

You could also just filter at unloading, remove that filter buffer warehouse and send the main storage to LTN.

Since my design works so well, I see no reason to change it. It also confuses everything when I count something and then take out 200,000 by hand. I don't think much of such complicated circuits. And there are ores what are wasted if storrage are too full - only with that the Coremining will be continue.

Or I misunderstood it.

This is what i make for transport multiple products with loader (yes arms are more easier but i thing needs more performance - and yes also circuit network needs performance too but for me this is te nicer way than 18 arms for a waggon and the red loaders are later upgrade to 90/s loader)

Provider

This station can handle multiple items and will only load the amounts scheduled to load.
Note: Overloading up to 1 cycle per inserter is possible, use locked slots per wagon signal.

Why is don't work?
Configured according to the blueprint. The train arrives at the loading station, but the filter manipulator does not load.
What is wrong?

Just about to set up my first LTN network in a Krastorio 2 save and I'm struggling to get my head around how to manage air filters, I was hoping to be able to have a single 1-1 train delivering new filters and collecting old ones for recycling. I was hoping to set this up at existing stations rather than set up a separate station at every city block.
So there would be one station that provides clean air filters and unloads the used ones for recycling, and then for example at an ore loading station i'd have 2 chests on the other side of the tracks from the ore loading setup with filter inserters loading/unloading the filters. Is it posible to set this up with LTN?
I'm sure someone must have used a system like this before in K2 but my googlefu seems to be failing me as I can't find any mention of it.

Sorry to necro this but I didn't see a responce and this might be a recurring problem.

This can be easily done simply by using filter inserters and wires and having both a request and provide limit. On the other hand I don"t think this will work due to differences in scale.

I might be totally wrong here, not knowing Krastorio 2, but don't you need far fewer air filters than ore? That means you don't want to have a station that unloads 8 cargo wagons of ore to also request 8 cargo wagons of air filters. You can't have different limits for different items at the same LTTN stop. So if you want trains of size 2 (LC) for air filters that also means you allow trains of size 2 for copper ore. You can probably make suure not to have any copper ore poviders that allow size 2 trains so this isn't an issue. But you also need to set a requester stack size of 40 for the air filters. And then LTN will also request copper ores if 40 stacks of copper ore a missing. Then you get a 8 cargo wagon train for 40 stacks of copper ore. Overall not an ideal solution.

So I strongly suggest using 2 LTN train stops. With some car you can overlap both stations on the same track but using 2 tracks with completely separate stops and stations is easier if you have the space and looks cleaner.

You can combine the unloading station for clean air filters and loading of dirty air filters thorugh. There is a blueprints for a requester & provider station at the start of the thread you can use.
