For example LTN will use this L-CC train for a 4k coal delivery, expecting this provider able to load both wagons.
Hmm, I didn't think of that. I guess I could hard limit the capacity of the coal chests for this particular station by red X'ing most of the slots in the buffer chests. Then this particular station would never show more than 2k coal is available to the LTN system, and no trains that want more than one-wagon-load of coal would stop here. Thanks for the idea.

This is about car lengths, not about simultaneous deliveries.

It doesn't mention it here but the max and min length is set to 3 on the requester station.
I see what's happening there.
That's why I always warned how easy it is to produce deadlocks with min/max train length.

Edit: I'll delay 1.2.3 to add the fix to that version.

LTN does not know about special stations being able to load only some items to some wagons like in your screenshot.
For example LTN will use this L-CC train for a 4k coal delivery, expecting this provider able to load both wagons.
And does it matter? Abstract the wagons, requests are not assigned to wagons but instead to trains. For LTN, this train will pick and deliver 4k coal, it doesnt matter if its on one wagon or divided by multiple.
Now, if the user overbooks the train, configuring the system to request more then 4k.... its the user fault.

I actually would like to see some screens of those combinators settings. Are you gradually reducing the the stack inserter item amount to guarantee precise numbers?

Re-released 1.2.3
These desyncs viewtopic.php?f=23&t=46873 should be fixed. I havn't got time or others to test it thoroughly

Providers are only picked if their train length settings allow at least one train size to be serviced by it and the requester.
Will still fail in endless loops if no matching train exists. Just use sensible length settings.

Improved performance of checking duplicate names by using new events from 0.15. Also checks against any base or other mod added train-stop names.

The Mod is working fine for me. TY Opt

I have a request, a suggestion. On the stop itself, I find it hard to connect wires to the proper part because they are bunched up together . Often, I connect wires badly because I simply clicked sloppy. Maybe the stop itself could be laid out in a way that us fumblers are less likely to miss our intended target?

Thanks so much!
I realized not every station needs a full 4-4 train full of items; So having the ability to haul large and small amounts is rather handy.

Hello.

I been reading the last few pages of this forum post and I cant seem to figure out if this is a bug or not...

I got a train station that supplies Coal. I told train station that it needs to deliver so and so much, how ever the train NEVER stops loading and fills up the train so it times out.

Oh and I'm using the lastest version of LTN.

there is a 'AND' to much in the conditions. if I remove it, the train functions as I want it to, and how it used to work.

Use some combinator magic dude, pick a wire from the station stop to an arithmetic combinator with the setup "each * -1 | each", get a wire from the yellow combinator of the station to the output of that combinator, the wire needs to be the same color tho. Remember to set the station to "read train contents" then you hook up another wire from that combinator to your requester chest configured to "set requests", remember, wire with the same color.

See, in that picture of yours, you're using a belt-based loading, so you still need that combinator magic but instead of linking it to a provider chest you hook it up to your filter insterters and on the inserters you check "Set filters". By looking at the picture, that combinator is useless since that station would request either coal or coke so you should do this:
1- Place an arithmetic combinator with the config: "each * -1 | each"
2- Grab a Red wire from the station to the combinator input, set the station to "read train contents"
3- Grab a red wire from the yellow combinator to the output of the arithmetic combinator
4- Grab a red wire from the output of the arithmetic combinator to the inserters, set the inserters to "set filters"

That works like this: the train arrives with a signal requesting 2000 coal, the combinator outputs a constant signal of +2000, the station outputs 0 when the train arrives. Since the signal is positive, it'll set the filters on the inserters to that type of item. As the train fills up, each item inside of the train will become a negative signal added to the positive signal the combinator is outputting, so if the train has 1000 coal, the Arithmetic combinator will output -1000 and will add with the constant +2000 outputting the final +1000 signal. When the train fills up with 2000 coal, the signal that is sent to the inserters is 0coal, since 0 doesn't set any filters, the inserters will stop loading the train and it'll leave the station.

I actually would like to see some screens of those combinators settings. Are you gradually reducing the the stack inserter item amount to guarantee precise numbers?
I think the point being made was since there could be more than 2k coal in stock at that particular station, the system would send a train there expecting to be loaded with more than 2k worth of coal (more than one wagon worth) which the station would not be capable of since it can only load coal into one wagon the way I have it configured. So I suggested I can limit the amount of coal in stock to exactly 2k and not any more, then no train would arrive at the station expecting such a condition.

The combinator settings are a little hard to explain, but you can pick it all up in the blueprint string I posted earlier.

Essentially a single stack inserter works all the time and it picks up the first stack of coal. The single inserter pulses 12 coal to the combinators which subtract this from the output from the LTN train stop, then divide the remainder of the request by the number of other inserters (factorio seems to always round-down any fractional answer), and send that number to the other inserters. So if I want 50 coal, the first inserter picks 12. The combinators do
roundDown[ (50-12)/11 ] = 3 so each of the other eleven inserters pick 3 coal and load it.

Now 12 coal has been loaded by the first inserter plus 33 coal has been loaded by the other eleven inserters. Now the "counter" is outputting -45 coal so the single inserter sees +5 coal remaining and it loads the last 5 coal. Since there is zero remaining, the other inserters do not load any more.

For a single item loaded by a single inserter, it works very similar but there is no math needed for the other inserters and therefore less combinators are needed.

full blueprint again, if needed

I mean, the problem is, that i have a station which supplies all which is needed for my outposts... filter inserters filter and everything is working great... but since its "AND 2 sec inactive" it just keep addon ammo... and more ammo... and ... way to much ammo, even if i just request 50...

Use some quick circuit network on the inserters to only load the requested amount, so they stop, train goes idle for 2 seconds and leaves

Somehow, it seems I have a lost delivery in the system...

One of my provider stations, that actually is a priority provider has the station light at yellow and no request is being made to it. The request for oxygen go all for station 2 (which is also a priority provider) and station 3, normal priority. Seems like the station is blocked waiting for something that will never come. All trains are parked at the depot, no orders for them to complete!
