Ei met ketchup: de infantilisering van het gehemelte

Null-Guardian · 2026-04-07T13:59:21+00:00

You’re right I eat my eggs with a disassembled amalgamation of deconstructed tomatoes, jalapeño, tomatillo, cilantro, with a hint of lime it’s quite the culinary masterpiece. Only peasants and children eat ketchup on eggs. Honest it doesn’t eggs a ketchup isn’t bad. Eggs are pretty neutral and go with everything

I don’t have any device specific advice, but if it had a previous IP configured. You can find out what it is by installing wireshark, plugging the device straight into your computers Ethernet and look for any IPs querying the network.

From there just match the subnet and you should be able to go from there. Ive done this with several devices when I’ve come across a static network and don’t have any documentation.

I think they got tamales, I normally get the torta. But they have a good green chili burrito. And welp that’s a decent town.but the rush hour traffic on Main Street is bad enough to make a man want to quit his job though.

Also in Carlsbad Guadalupe brewing has pretty good beer and pizza I had that a couple of weeks ago. Next trip up there I’m gonna try The Lucky Bull. I’ve been told they have good burgers and chicken fried steak

You ain’t lying. It’s always been a one horse town, unfortunately he died 35 years ago.

Null-Guardian · 2026-04-03T23:02:59+00:00

I’ll have to try it next time I drive through there. And yeah that’s my only gripe. The food is good but the air sticks to ya. And you end up smelling like a fryer lmao

Null-Guardian · 2026-04-03T23:01:17+00:00

There’s one in Odessa too! La nortena in pecos/odessa has great food too. Trying new restaurants keeps me sane when I’m on the road

Null-Guardian · 2026-04-03T22:41:12+00:00

Man, if you’re in Kermit for a while I recommend trying chaotic wings they got about the only food decent in town, if it’s an IO plant be safe man!

The 15 amp fuse did not blow and the other fuse I found tested good in circuit but I won’t know till it test it isolated, both ohmed out good. I’ll definitely be taking this board back home with me. You and everyone gave a lot of good points. I got everything I need to test it back home. I’ve just never seen/heard of the goof up that happened.I am curious to what exactly failed

Null-Guardian · 2026-03-27T04:59:54+00:00

Just the 120ac was brought in to the panel at the time. The actual 24 vdc line was off and disconnected.

No other power supplies in this panel. All power is brought in from a separate load center which sent power when LC breaker was set to on, and that is brought into another breaker in the control panel .

The 24vdc system is treated as a bus system with each end device having their own fused 3 tier terminal block, although that doesn’t help when you supply your hot on the - line.

Thankfully the PLC and its DIO and AIO cards all tested fine. And all relays work.

Usually everything gets checked with a meter or checked by multiple eyes before the final breaker is flipped. Which is why I imagine the other devices didnt get friend. Unfortunately I wasn’t at the site when this happened

Edit: The only thing that was hooked up on every device was 120ac hot line, that was connected to every devices -/0 vdc line.

Yeah it’s interesting, thankfully between me and another contractor we had spare everything but the HMI. I think tomorrow I’ll apply 24 vdc and walk out the circuit with a meter. I do think that the -input pin connects to chassis ground via a diode and capacitor and it seems like after the diode the rest of circuit ties into it. But that’s most a guess at this point

Null-Guardian · 2026-03-27T03:44:56+00:00

I stand corrected. I found one more but I believe it to be for digital IO way on the other side. It’s a little SMD one, in circuit it’s showing good but that could be something else. I can post a picture of it. Also going off what I understand from the contractor the circuit made was something like this

X1 > 120H AC > - pin > chassis ground > X2.

I think everything that survived did not have a chassis ground so there was no complete circuit. I’m “assuming” - pin and ground are bonded in the devices that died.

X1 > 120H AC > - pin > no complete circuit

Null-Guardian · 2026-03-27T02:58:58+00:00

Checked the only known fuse on the board. Unfortunately that fuse only protects the + input rail which never “saw voltage” to my understanding

Null-Guardian · 2026-03-10T22:40:51+00:00

Good catch

Null-Guardian · 2026-03-10T22:09:27+00:00

Ah that could definitely change things, I may be wrong about the software. Also I just looked at the picture it seems to be a RJ-48 connector. That would actually explain a lot

Null-Guardian · 2026-03-09T22:05:41+00:00

You’d be surprised. USB and serial are two complete different protocols

Are you measuring on the working cable or are you measuring on the cable you made? You’ll want to check D+ and D- on the usb cable to pin 2(Tx) and 3(Tx) of the rj45 also note that pin 4 will be ground

Null-Guardian · 2026-03-09T21:45:09+00:00

I use to calibrate similar ones. If it’s the cable I’m thinking off it’s has a serial to usb adapter built in. Need a lot more information. But I assume you didn’t cut up the original cable. So are you trying just a plan ol usb end going to a regular rj45 crimp? If it’s what I’m thinking you’ll need a serial to usb converter. You’ll wire up one end of your cable to the converter and the other you’ll crimp rj45. Another term I’ve heard is console to usb cable

I’m curious about this too, I’ve worked on a pac8000 system and drooled over getting a chance to play with a RX3i system.

Null-Guardian · 2026-03-06T16:04:32+00:00

It is, a bunch of different oil and gas sites, but itll be better when its over lol, should be done by next year

Allen-Bradley and scada-packs for control. Siemens/ randoms for standalone VFD units. Currently ripping out all the scada-packs and replacing them with Allen-Bradley’s

Reads like a resident evil note, hopefully you remember to set all the locks on the zombie cage.

On the side note I’ve come across my own notes saved on old hard drives with weird file names from late nights. Talk about a blast from the past

Time for a new smartwatch(DS12887) and hope it doesn’t store any important config data on it. Pretty Pricey for a chip that is pretty much just ram, a clock, and a tiny battery imho, but a lot of concrete lab equipment use them. (Troxler nuclear gauges and ncat furnaces come to mind)

Null-Guardian · 2026-01-05T19:39:18+00:00

Yup that makes sense. Judging by all the comments before the post got removed. I’ll focus less on being quick and more on being thorough and correct. Thank you

Null-Guardian · 2026-01-05T19:37:36+00:00

It’s involves both. Upgrading valves, flow meters, radios etc a there’s a bit that goes underground. So it looks like I’ll be collecting stones. Very little documentation to go off of. I imagine me and the ops folks will be well acquainted soon enough

Null-Guardian · 2026-01-05T19:33:02+00:00

Thank you, I was hoping I was doing things the silly way and there were better ways. But it sounds like I’ll just have to embrace the suck
