I recently won a Siemens Simatic S7-1200 PLC with software license

ever heard of a transformer?

SkillsUSA?

AWWWW YEEAAHHHH. State champion, nationals second place, and I competed on the WorldSkills USA team.

Good choice, m80. I just hope your industry doesn't die as soon as you win medals like mine did

The reason they gave you a plc is nothing to do with letting you build something cool or exciting it's purely a marketing circle jerk.
You put in effort to your project for this competition and then they reward you by essentially getting you to use their product and try to influence any company you might work for in the future and give you some hardware that costs them literally nothing to make and then make you feel like you owe them something? Fuck that
If you have any integrity you will throw it in the trash, otherwise put it on eBay and buy yourself something for a project you actually want to do

I looked a bit and cannot find anything to do this directly. :|
There is a shit-ton of inverters that convert 24vdc to 12vdc, and a shit-ton of inverters that convert 24vdc to 115vac, but I could not find one single converter that would convert 12vdc directly to 24vdc.
,,,,,,
So it's a 115vac inverter, and then a 24vdc power supply on that.... My inner autist is not pleased. :[

Also I can only find stubby little pieces of DIN rail on aliexpress. WTF?

If you wanted it for home use, you can get a little DIN ps for like $15--pic related
(I could not find out how much basic current the damn thing draws... the manufacturer's website has 5000 links saying how great it is, and no link that gives the basic specs. I'm sure there's a real-actual-spec-sheet somewhere on there, but good luck finding it)

Lastly--before using this thing for anything real impressive, I would want to know what happens when that software license expires, or that version is no longer "current".... Will you be able to do anything with this PLC at all? I mean,,, it will keep working as it is, but will you still be able to change the programming at all?
-------
A lot of programmable industrial level stuff has tag-along/maintenance costs. Software is often one of them.

An s7 1200 is way overkill for anything you can do in a car.

Still, if you wanna use it, then use it.

Hook two 12v supplies together to make a 24v source.

I meant to add: Din Rail is cheap and easy to find here: http://www.newark.com/webapp/wcs/stores/servlet/Search?pageSize=25&st=din+rail&catalogId=15003&categoryId=800000004816&langId=-1&storeId=10194

>>1048067
I will buy this off of you as I am an automation tech and would love a decent PLC to hone my skills on.

temp email, shoot me a timestamped proof of you having this and we will talk

Does this work? ,,,,,,, Is it wise? ,,,,,,,
Internet experts express cautions about it being perilous.

I was always under the impression that you're not supposed to hook power supplies in series OR parallel.

Google "DC to DC step-up converter 12-24v" - theres about a million of the fucking things, from about $9.99 upwards. None of which makes this anything other than a solution looking for a problem, but, nevermind.

What is a step-up transformer?

>>1048404
It takes a lot more than a transformer to step up DC voltage. It is easily doable but just saying "transformer" is flat out retarded. The addition of "step up tranformer" further confirms the retardation/bait.

>>1048387
How do you think batteries work when you put more than one in anything? Hook 2 1.4v AA cells together you get 2.8v and power a TV remote. Hook 6 18650 3.7v batteries together for around 22 volts and power a laptop.

Hook 2 car batteries together and you can run a 24v PLC no problem. Actually finding a way to make a single 12v battery give you 2 independent supplies might be more of a challenge but I'm sure it would be possible with a bit of thought.

I know about those, but the ones I've seen don't have real generous current limits. And most I've seen were really pretty dinky.

A (switched-mode) power supply is not the same thing as a battery...

>>1048482
I thought the point was to put it in a car.

Siemens simatic S7-1200 is junk. You should sell it on eBay and stick with Allen Bradley.

Pic is from a service call I was on recently for a Kodiak cartoner using that same plc. one of the outputs fucked up so as to that it was always outputting 24v. I didn't have Siemens software installed on my laptop at the time so I ran a wire from the input (photoeye) right to a motor relay and bypassed the plc. A week later I got a call that one of the glue head wouldn't stop firing glue. Another output fucked up and was stuck on. I readdressed the 2 outputs to spares and haven't heard back yet.

tl:dr I've seen Siemens units fail more often than Allen Bradley. Don't trust that unit.

Nah, you have to be retarded to believe that a step-up transformer is nothing more than a transformer.

>>1048433
Takes a lot more than a transformer to step down DC voltage correctly.

I guess we have a lot of idiots, but clearly you must be a genius.

Make a mdf board up with some din rails, psu, lights, cable management and anything you fancy of ebay and just try things out. I cut my teeth buying shit products like a bread maker, gutting the pcb and trying to replicate the functionality

No one in the US uses Siemens.
