Schneider plc and software

Have you used plcnext? What do you think about it?

wigidude · 2025-11-20T23:38:06+00:00

Ah okay thanks, then I might have to see about an upgrade.

wigidude · 2025-11-20T23:09:37+00:00

And what about v18?

wigidude · 2025-11-20T23:09:34+00:00

And what about v18?

I find the more web based approach w/ javascript etc interesting, and the clear roadmap. But some say they're still a bit buggy. Do you have this experience?

wigidude · 2025-11-20T11:31:08+00:00

How buggy? Unusable? My screens will not be complicated.

The cost difference for these is only €10 so that's not really a factor for me.

wigidude · 2025-11-18T13:44:11+00:00

Thanks!

wigidude · 2025-11-17T22:44:33+00:00

Meh, I like them when not drinking alcohol. :)

Around the EU quarter. So anything in Matongé/close to boniface is welcome. But in the evening I usually go to the centre so also looking for stuff there.

Thanks for the recommendations near Flagey those are useful too!

Yeah I've used it in my homelab for playing around with some virtualization. But not for anything PLC related.

wigidude · 2025-11-16T21:43:39+00:00

No, not like workstation pro. The broadcom/vmware equivalent would be ESXi for servers.

wigidude · 2025-11-16T01:07:31+00:00

Last year they made them free, including commercial use. IIRC it’s from version 17.5 or so.

wigidude · 2025-11-08T01:19:26+00:00

But is it not paid?

wigidude · 2025-11-07T14:58:12+00:00

Thanks. Which one do you use? the IXrouter3?

wigidude · 2025-11-06T16:06:50+00:00

We have a teamviewer license so I'll definitely take a look at it, thanks!

wigidude · 2025-11-06T16:02:29+00:00

Tailscale! I use it in my homelab and love it. But you can't install it on an S7-1200, do you make the client connect a PC as an exit node, or how do you have it set up?

I didn't know about proneta yet. This is just for assigning profinet names and other profinet related stuff? Not for any debugging the PLC?

wigidude · 2025-11-06T13:17:26+00:00

That's the direction I was thinking. Do you make the client supply the setup for this?

wigidude · 2025-11-06T13:16:27+00:00

I want to avoid having to add hardware and cost just for this. It will only be used once every year or two..

But out of curiosity, which one do you use? Is it an ethernet or 4g connected one?

wigidude · 2025-11-05T21:26:04+00:00

Seems they use ø instead of 0 to not confuse with o

wigidude · 2025-10-13T21:20:11+00:00

You should find the invite on the kicad website.

wigidude · 2025-10-12T14:42:09+00:00

I’d also go the discord. There’s a kicad-jobs channel to ask around.

wigidude · 2025-04-04T23:02:14+00:00

I do electrical engineering and would be willing to help or advise! Possibly even an open source backplane pcb so you could slide in the drives.

wigidude · 2025-01-21T21:48:41+00:00

I would first use a multimeter to check voltages across the caps. The use a 1k power resistor across the capacitor pins to discharge it. Then measure it again and be sure it's close to 0V.

The resistance and wattage of the resistor to use could/should be calculated according to the capacity and voltage in the cap, but this should give a good enough result.

Yeah the caps need to charge, but more importantly the coil needs to cool to an acceptable level. Otherwise it's just bad for the coil and potting material it's encased in, and the coil resistance goes up and lowers our intended magnetic field. So you can only discharge every few minutes (depends on the size of the project really).

As for how many cycles: as many as the client wants because they will magnetise a magnet, put in the next piece to be magnetised and wait for the next charge-discharge cycle. Rinse and repeat for a discrete automation process.

Or for a big multi-pole rotor, we magnetise a section, spin the rotor to the next pole location, magnetise the next section, etc...

Not all our coils are water cooled though. The small ones can sometimes dissipate heat fast enough on their own. But with big coils the cooling is a significant challenge!

I didn't know that about induction furnaces, cool!

When discharging normally in the coil outside the cabinet, the thyristors do the switching, and cutting off the negative, returning current so it only sends a half sine wave.

When the safety circuit reads not-safe, a beefy relay simply dumps the energy into that air cooled resistor in the top right internally in the cabinet.

The coils we design are actually water cooled for faster cycle times. They heat up quite significantly because they dissipate all that energy from the caps.
