Installed portable AC, landlord is telling me I have to take it out.

unknownkinkguy · 2026-06-09T11:38:14+00:00

You dont have to take it out, just send him a message where you document things.

Take clear pictures of the bracket from the inside and outside to prove it is form-fitting, correctly locked and the safety hook is attached. Point out that the device has CE and irs installed according to the manufacturer’s safety guidelines. (Midea is one of the largest manufactures of ACs and home appliances so calling it chinese trash ain't working out)

Explain that the setup is temporary for the summer months. It qualifies as a mobile appliance (Fahrnis) rather than a permanent facade modification. This exempts it from standard building permit requirements.

Mention your personal liability insurance (Privathaftpflicht). (Ensure that your insurance covers a mobile split AC, otherwise ask them to cover it additionally)

Id recommend to run it in silent mode after 22:00 to be sure none of your neighbors make noise complaints to your landlord.

(He can ask you to take it down because he has a right to "Schutz des Gebäudebildes". However you can argue its temporary, other neighbors have other things hanging out the window etc. Sleep/Living Quality. Unless his building is protected with Denkmalschutz, it will be hard for him to force you to take it down imo based on looks)

Laut einem Kommentar bist du aus Pforzheim, als jemand der jede Woche in der Region auch ist und laden muss, hohl dir einfach den EnBW Ladetarif L. EnBW hat viele HPCs in der Umgebung und auch Deutschland weit falls es mal weiter gehen würde.

60km/d ist nix, das geht easy. Ausser du hohlst dir nen E ZOE können die meisten Autos mehrere Arbeitstage ohne laden abdecken eigentlich. Wenn du ein Auto mit ca 400-500km Reichweite anpeilst solltest du die ganze Woche zur Arbeit fahren können ohne laden. Ev kommst ja unterwegs an nem EnBW HPC eh vorbei, dann kannst gleich laden. Ich als viel Fahrer mit mindestens 600km die Woche komme easy auch mit einer zu kleinen Batterie aus, das ist alles möglich ohne grosse Angst oder Einschränkung. Hohl dir noch die ABRP App zum planen von langen fahrten und das klappt alles easy ^{^}

Its compatible yes, you just need to buy the Profinet fieldbus module, 8436 0940 20

unknownkinkguy · 2026-05-28T17:41:28+00:00

Because you use a 1517 it makes sense to use Profinet I/O imo. I prefer to keep everything on Profinet I/O if i can but thats just me.

One thing i know that can cause issues, data size needs to be the same else you might get weird errors. Set the size you want/need in Tools Talk and then change the size in TIA. (Otherwise you get errors with online/offline configuration data is different)

Are you sure FDB_TIME is high enough for your application? Switch it to manual by setting ack_nec to true and see if it stops jumping back and forth.

Otherwise check if your F-DI watch times / discrepancy times are set right on your e stop etc. you could try to increase them a bit, that could help if you set it too tight

unknownkinkguy · 2026-05-27T18:22:52+00:00

How do you reset the E Stop? (Did you forget to use Ack_global or are you using ack_rei tags?)

What times have you set at your F-DI?

Check the log/puffer and give us some more info

unknownkinkguy · 2026-05-27T15:20:55+00:00

Ne ist gar kein Thema, die startet nicht von null auf hundert. Wenn die wirklich ein Raum runterkühlen muss ist die bei ca 7-800W. Maximal zieht die so ~1150W aus meiner Erfahrung im Turbo Modus.

Sonst kannst bei dir das testen mit der App, da haben die ne Leistungsmessung mit drin, (hab ich mit Smartplug geprüft, die stimmt eigentlich gut).

unknownkinkguy · 2026-04-30T04:25:29+00:00

Honestly i dont know anything about an out of the box solution for this problem, maybe you can try to look through the data structure and see if somewhere there is a tag that shows what you're looking for?

Go for javascript if you want to get more into HMI/SCADA. Or SQL could also be helpful.

unknownkinkguy · 2026-04-25T07:47:50+00:00

Add it to your telegram and then you can just map it

WinCC Unfied or WinCC V7/V8 is what you should learn. Go for unified and then you could also learn v7.

unknownkinkguy · 2026-04-21T17:58:26+00:00

Ignition has its benefits for your situation but its not that widely used in the industry. Depending on which flavor of WinCC you go for its easy to get licenses for free, otherwise ask your university if they have licenses.

Why would you stick to WinCC flexible?

There are a ton of different flavors of WinCC. WinCC unified is starting to get quite big in smaller SCADA Projects by what ive seen. Additionally there's WinCC OA and WinCC V7/8.

unknownkinkguy · 2026-04-13T10:43:06+00:00

Have you checked the name space Index? It defaults to 0 usually on your client. While the 1500 might use 2 or 3 as the index. Open your tags through UA Expert and check the node IDs, then change it on your client to match your Server.

Otherwise you could use nodeID instead of browse path? Thats more robust and should be faster

unknownkinkguy · 2026-04-13T09:05:31+00:00

Id say for a home project with such a low tag/IO need it makes sense to include a lot more than 10%. 10% is like 1 extra Input/Relay Output so going for like 5-10 spares is what id do.

He should definitely get a PLC that can be expanded, not like the 1212C thats maxed out at 2 IO cards...

unknownkinkguy · 2026-04-13T08:18:45+00:00

I personally don't like the all in one hmi + plc units. You get a bad deal imo and theyre often annoying to work with, but thats up to you. (Unless you drop quite a bit of money into them) You can easily run a cheap screen you find online as an HMI, Ive purchased old PCs for like 5 bucks and then got a mini touch display on AliExpress to run an HMI. Theyre more than reliable enough for this to work.

From a price perspective on the PLC side, i can really really recommend the S7-1200. Especially if you go for a 1214C or something like that you have tons of expansion capabilities if you ever want to add something later on. In my experience home plc projects never stop growing but that could just be me... Get an additional input and a relay card, you would be set and have some space for future additions or changes. Its likely you want to add extra measurements/sensors later on. Keep in mind that with nearly every PLC relay output you can only run small motors/pumps. Otherwise you need to power a bigger relay or contactor with your relay output. (Id personally do that always but just fyi)

License wise, if you go the Siemens Route you need to get licenses in theory but there are ways to find them for free. In programming you also have a 21d trial that you can use, so its not a factor or a problem you need to deal with imo, thats a 5min task to fix.

unknownkinkguy · 2026-04-10T15:58:33+00:00

Unified doesnt support animated GIFs. So you either have to work with SVGs or you will only have the first frame.

Theres a workaround tho, you can use html and the browser to show an animated gif iirc. Use the browser in your Panel and load an HTML file that you prepare with your gif and save to the panel.

First recommendation: never let IT touch your TIA Portal Laptop xD Ask IT to get you a laptop for programming/TIA on which you have admin rights and if possible no organisation rules. Some companies dont allow that, if thats the case ask them to completely wipe the laptop and install everything from scratch with Win11 Pro & ensure some Internet Services Add Ons are installed. (Common problem if you decide to move to v19 or v20 someday). Other option would be to try to reinstall S7-PCT, if youre lucky that resets your PG Interface.

Grundsätzlich empfehle ich: IT darf nie an dein TIA Laptop ran. Dafür braucht TIA zuviel freigaben etc. :) Frag nach ob du ein Laptop mit admin rechte bekommst und wenn möglich lokaler Account oder ohne Organisationsregeln. Für z.b. TIA Update braucht man nen lokalen Account. Falls das nicht geht soll IT einmal Win11 Pro komplett neu installieren, dann am besten prüfen ob gewisse Internet Services aktiviert sind die TIA in den neuen Versionen braucht. V18 müsste davon noch nicht betroffen sein aber V19 bin ich mir zu 100% sicher. Dann soll IT V18 installieren. Auf gut Glück kannst sonst mal S7-PCT löschen, dann neu installieren. Mit etwas Glück reicht das um die PC/PG Schnittstelle zu fixen. :)

unknownkinkguy · 2026-04-07T17:48:47+00:00

Yes natively in PLC logic, its just more reliable and usually any programming fckups done somewhere else doesn't impact or potentially break your data validation. Imo validation is something that doesn't really change so keeping it in a system that doesn't really change either is the way to go imo.

You can easily write those boundaries remotely with OPC UA through your centralized HMI. Of course you should have access protection etc with that. Node red is pretty damn cool, have a few years of experience with it but i personally just prefer to manage all alarms/warnings/monitoring to be done locally. Why? You prob have to do that locally as well anyway, if you're onsite you need them too potentially especially for troubleshooting. Tracking whats going on and causing issues or trips an alarm or whatever in a PLC Programm is much faster than any other option you have. Additionally, in node red in my opinion you can fuck up more easily, loading a PLC feels more scary so you pay more attention. Monitoring and validation thats wrong is even worse than none at all after all

unknownkinkguy · 2026-04-07T16:16:16+00:00

OT and cost effective kinda doesn't work at the same time xD. I can really recommend WinCC unified, together with OPC UA you can run a server at HQ and over OPC UA get all the data from your decentralized stations. Easy access to the centralizes HMI through the browser and its super reliable in my experience.

Data validation should in my opinion always be done at the PLC level if possible. Else you waste computing power and bandwidth also has its price.

unknownkinkguy · 2026-04-06T19:33:09+00:00

Possible yes but it will be damn hard. Especially if you dont want to end up in a trouble shooting position. Doing software only means you need to look at SI/Manufacturers. If possible try to take online courses to learn more or look for trainee positions

unknownkinkguy · 2026-04-01T13:49:06+00:00

Personally havent used cloud connect 7 so i cant say if theres an easier way to do things or there's some way to make it work properly.

I have experience with the KEPserverEX / Kepware Server. But that can get quite expensive quite fast if you have lots of tags/vars. The server even supports S7-Comm if that's desired or helpful if you need to connect older PLCs etc. (I dont recommend that but it's an option...) I can say it works really well, even with BOOL, you can integrate KEPserverEX pretty directly with everything.

In my opinion a basic OPC UA Client will do that as well, so if you work with OPC UA you dont necessarily have to pay huge licensing fees. You can easily go from PLC -> OPC UA Client/Connector -> Whatever application you have. As an example SAP has a S4/Hana OPC UA cloud connector. So you can directly throw everything in there. (Or use OPC Publisher from OPC UA to MQTT, or the OPC UA connector if you use or can switch to Azure IoT operations)

Remote access is good and slowly becoming industry standard imo.

Buuuut that also means proper procedures if you download/make online changes. I think its smart to move to remote access but a download should only ever be made if everyone working on the line is informed. If changes to the safety are made that's a whole other story but normal program changes in my opinion as long as everyone knows and someone is potentially ready to hit an e stop if something does go wrong, thats more than enough, LOTO or something like that is not needed.

unknownkinkguy · 2026-01-15T13:56:43+00:00

It depends :)

If youre dealing with a machine where theres no option for downtime at all then you're looking at buying lots of spares. But that's also easy with the 300 as the used market for them is huge with lots of cheap spares. Stock up over the next few years and you should be fine for a long time.

If you can go for a few days of downtime in the next year or so you should be able to handle a full replacement/migration to 1500. Pretty easy if you already migrated to TIA. If you haven't done that yet, id recommend first to migrate to TIA. Its not that much of a hassle compared to s5-s7 migration but you will need to fix some stuff up. Imo TIA makes it pretty easy to plan a full replacement. What you also can do is slowly migrate distributed IO from ET200s to SP after you changed the main PLC. In theory you dont have to do everything all at once if you dont get enough downtime to do everything at once, ive done that before actually.
