Hey Bruce it was a bit late when I read your message. By the looks of it I think in the siemens s7 we have the function block diagram. There are codes and blocks with conections that don't seem to go anywhere. Now that I see your message I think I should have a look at it. I could really steel the show if I have some knowledge of it.

Node red is not a language to put in a plc, at least as far as I know, I think you can talk to it with modbus or OBD and and do a lot more with your plc.
Quick look on youtube, www.youtube.com/watch?v=fV78MQks6BI, just scroll past the install stuff and you can get an idea what you can do.

Greetings Bernhard

Hello bruce, I will read it and have a look at it. I like this stuff so I like some new input. Come back to you later.

Hey Bruce, the only language I "know" is C I put a lot of time and effort to master the language. At moments I came close, but after a while .... at the moment I can sort of read the code and understand what is happening, it's not so hard actually.

Mqtt is just made to send short messages or to reseave a message to do something((Message Queuing Telemetry Transport) is an ISO standard (ISO/IEC PRF 20922)[3] publish-subscribe-based messaging protocol.). Small and powerfull.  Node red can do also  someting with mqtt but it's really powerfull it's not some half ass attempt. Just google or have a look on youtube.
It's standard inside raspberry pi.

Hey Bruce I know you do not like other people's software but I am not smart enough to make something myself from scratch. There have been times I came close but after a small year most of my skills are gone again.
With the "new" esp8266 you can collect data send it wirelessly with mqtt to a broker and use node red to control all of it. Node red is also something to google. Really interesting. You can do your "coding"in there it's graphical.  Just like to encourage people to have a look, it's not hard even I can use it.

You mentioned the teensy board, I heard about it but am not familliar with it. I saw you can also program it with arduino ide.

In my job we have mostly siemens s7 plc's there is no ladder diagram inside (was made 2013). Nobody in the group has really the skills to really find what your looking for in the raw code. There is scada wich gives you access to certain things but at times you need to adjust a timer or such and most of the time it takes a day to find what you need to change where. I really don't know what they used for programming they have remote sessions to adjust/make changes.

So in short with mqtt and node red and some microcontrolers of your choosing you can make something complex dirt cheap and with very limited knowledge. Have fun.

Greetings Bernhard

Heavy respect to work with plc's I had a look into it when I started to get something automated, for the expenses and the diffeculty I decided to go the arduino route.

For somebody who is not into electronics and programming I would highly recoment just to have a look at it. It's really cheap and there are so many people busy with it you can just use the code from somebody else and adapt it a little to your own needs. Now there are the esp8266 boards that are super powerfull and have wifi on board and you can program it with arduino. They cost less then 4 dollar in china.

Just a message to encourage people not to get scared away when it comes to automation,

Greetings Bernhard

Nice project, just had a quick look on youtube,

That should be it I guess.

Original Lister Cs Engines / Re: New engine and parts from India
« on: January 09, 2019, 01:51:47 AM »
Posted a picture from the water cooled injector head, A picture of the rods with pistons, put a normal piston in the middle for the contrast. One rod is wider at the big end, but if you tilt it it passes the cilinder.

And Bob you got a good point with the scraper ring, should do some measuring.
To be honoust I am totally not familliar with all the oversizes, has also to do with the inch/mm thing. But I have some cilinder blocks lying around that are a lot bigger then standard.

With these blocks(of this one) and pistons I have the feeling it is very early type, the guy also tried to sell me the old injectors with the push pin on the top.

i think I will move it to his new location and save the rest of the fun for a later time. Still got a lot of work to do in the new location, busy with heating now to make it more comfortable to be overthere.

And again if somebody has smart ideas distilled from the pictures I am all ears.

Hey Bob did you notice the freeze plug in the bottem of the  cilinder block. I was also looking at the liners, that would be nice if they are wet liners. Size is 115.6mm liner and 115.4 piston. standard is 114mm so somebody been busy with it.
Some strange parts in this engine.

Ok here the update,

I've been busy with my new garage put a 65m2 atic in it and now slowly moving my stuff overthere. Most of my engines are allready there. The 16-2 is a bit heavy for the old trailer and I was really anxious to have a look inside...
So took the heads of with the watercooled injectors, didn,t open that yet, and had a look inside the cilinder. Could clearly see where the piston rings been sitting for years explaines why the guy filled the engine with oil to get some compression. So far so good.
Took the first piston out, big end bearing worn out pretty much, Thats a funny piston.......... especially the scraper ring tsss...
Ok next block.. I could not get the piston out...the big end is bigger than the bore of the liner... Took them of together. On the crankshaft you can see the imprint of the bearings this engine has been sitting for  many years.

So on one cilinder a piston with a scraper ring that has enourmous play, you can almost fit two, the other piston they left it out. I have the feeling it's a prehistoric cs piston that didn't use scraper rings ?. I have two different piston rods with one not passing the bore.

At least the crankshaft looks in a reasonable shape, 2 flywheels. Should be able to build something out of this.

If somebody has ideas about the pictures and the parts I really like to hear the opinions and ideas.

16-2 magnetic piston update.

I need to trim the engine down for weight a bit to move it to my new location and I am curious what to find......first some pictures...

Hey glort why don't you start mining altcoins with free electricity it's still profitable..

Generators / Re: Remote stop

On the start o matic lister cs there is a resistor connected to the sollenoid to reduce the amps going to the coil when it's running, works with a switch thats being pushed by the fuel linkage.

Also with a multimeter you can see on witch wires you got reading and witch on not. and the start o matic was 24v.

just an idea

Listeroid Engines / Re: field marshal with gas connection
« on: October 26, 2018, 02:14:10 AM »
Thanks for that I was just correcting my lazyness by posting the wiki of both.
Propane is a popular choice for barbecues and portable stoves because the low boiling point of −42 C (−44 F) makes it vaporize as soon as it is released from its pressurized container. Therefore, no carburetor or other vaporizing device is required; a simple metering nozzle suffices

butane
Boiling point   −1 to 1 C; 30 to 34 F; 272 to 274 K

Hey glort I knew you would dive in, the gas thing was just out of interest and the fact when I store my boat in winter I need to take the bottle out for insurance reasons.  So engine + bottle....

If I would use the bottle sometimes I would use a torch on the bottle to get the gas out, it would freeze.  (sounds more dramatic then it is). Not bullshitting propane and butane have verry different boiling points, to lazy to look it up again but butane beeing someting like 10 degr celcius. So if in cold weather your draining the bottle....Thats why in summer you have a load more butane like 30%. You can find it somewhere on internet.
But the last bit of the bottle was not nice to run it really started to knock badly.

With the natural gas the economic reason is not there in my case almost same price, but I used it and it worked only I should increase flow, was like 10 % of the load.



I know one point your very keen on the water injection, if you burn fuel you got a lot of water aswell  hydrocarbons...with gas I believe its even more. I was condensing the exhaust gas so I already got liters of water draining from the heatexchanger and when the boiler reached it's temperature the condensing would happen somewhere further down the line making a mess.
I'll promise that when I start the plant up again I will give it a try with extra water but for the exhaustgas heat exchanger I do not see the advantage (yet). Promise one day I will try.

For the last years I put to much time in my chp plant I need to catch up with some other stuff I still work and just bought some garage that I am busy with.I love this stuff so it will start again.
