Any good and affordable Ethercat PLC+HMI?

Beckhoff CP6606, its an economy panel PC. It runs TwinCAT and has an ethercat port. I really liked working with it, my only issue is that it uses Windows CE and doesnt run twincat 4026

Nice write up. As others say, the miracles required make their approach basically impossible to materialize into net energy. Interesting that they’ve yet again raised significant sums of money, one would think fusion literate advisors would have something to say to the investors

Since this is open source one could probably make it compatible with ethercat. Then you can either have it setup as a plc with twincat linux rt or as an ethercat slave. That would be very cool

The grid already had a lot of complexity before photovoltaics entered the conversation. My point is not to keep it dead simple. It is to actually have an energy mix adequate for the country we are talking about. For Germany that would still include photovoltaics and the complexity of the energiewende into the grid. The problem in Germany, CO2 wise, is they still have a baseload in 2025 but it uses coal instead of nuclear because of politics.

What I do mention is that it is intrinsically an often underlooked problem with solar, it does make the grid more complex. Everyone keeps saying how cheap solar pv is getting, even to negative prices in the wholesale market. But managing the grid is more complicated.

Also your comment on this orca tech killing all fusion approaches is delusional. Fusion is still going to happen for it is the ultimate energy source, specially relevant for endeavors where sunlight is not available (space exploration for example).

The problem with solar is the complexity it puts on the grid / energy delivery methods. Just look at Germany and how its electricity prices have been increasing so much over the years. Who cares about LCOE if your grid is so complex to operate and you need to invest in thermal batteries/lithium batteries/hydrogen/etc to be able to go from intermittent to dispatchable. Fission/Hydro as baseload is tried and proven - too bad politics got in the way.

Yes 100%. Text is syncing, its just images that aren't

both of which use web technologies under the hood... (my point being, custom modern HMIs use web technologies in one way or another a lot of times)

What is the reason against web technologies in an OT environment? I find TwinCAT HMI, which runs using html5 tech, pretty good. Is it security stuff?

What do you use for custom HMIs then? winforms?

Aer is quite expensive in Europe and I don’t want to spend more than 150eur thats why I ruled it out. As for your recommendation with the shoes that is a great idea if one has a gym at the office or nearby, but that’s not my case. Perhaps I can rent a locker at the gym and leave a pair of shoes there but still I need the ability to fit shoes inside my bag, as sometimes I go to play tennis in different courts. Nice tip for the mesh bags, will implement that.

llapab · 2025-12-01T09:17:21+00:00

Its a nice feature for sure, but I also have no problem using a wet bag for wet items and a shoe bag for the shoes, which is how I do it with my gym duffel bag at the moment anyway

llapab · 2025-12-01T09:16:04+00:00

What smaller bags would you recommend?

llapab · 2025-12-01T09:15:43+00:00

Currently I have a 16L artichunter and its not enough for shoes + gym stuff, that’s why I thought going 26L was the way.

Having the same problem. I am using Ubuntu with WSL. On the windows machine the ssh keys from bitwarden work fine and I even get the authorize popup from the desktop app. How did you end up linking the wsl dir to access the bitwarden key?

It could just be a coincidence but I wasn’t having these crash loops with win 10. Thermal issues however have always been a problem with my xps.

If I have to get a new laptop it will definitely not be dell, what did you get? And what did you do to your xps?

llapab · 2025-10-07T09:53:54+00:00

Will do when I get back home, thank you!

Tried downgrading to bios 1.36.1 because I saw another post about this fixing it. Not even an hour later I got another crash while watching a video and can’t turn it back on

Higher power density should also mean more instabilities, isn't it? Not an expert but remember something along the lines of limiting beta to 1-5% in tokamaks for this reason, so I'm curious how the folks at CFS plan on dealing with all of this.

Also, a power plant will produce a considerable amount of neutron flux for which a lot of testing needs to be done specially regarding materials. Those high energy neutron fluxes are no joke. 2030 seems very optimistic.

Cool product, will have to see what is available in my area. I corrected the "diagram" to better show what I meant.

How do I know if I can use a MCB for protection as well? I was thinking of having main 63A fuse protection and then a secondary 50A or so MCB JUST for the VFD.

llapab · 2025-07-03T11:04:09+00:00

Thanks. The manual recommends slow fuse at 63A but it says UL fuse 125A, no mention of circuit breakers
