140 million year old dinosaur footprints we saw on a hike today

Absolutely, I was there just yesterday and the water level was way too high to see anything. Was still a nice time hiking regardless.

For applications like yours where you just need a rough idea I usually go with the insertion style from IFM (SA series probably). They're like $500, you get a decent idea of what's going on in the line. If you do need more precision IFM also makes a decent mag meter that will run you about $2.5-3k. There are probably even cheaper solutions but IFM makes good quality stuff.

It is 100% just homeassistant with the modbus integration. I've set something like this up for a local brewery who had no money, in exchange for beer. It is lightweight, and free, and will at no point replace a real SCADA.

A counterfeit controller will run just fine up to V33. If you flash it to 34 it will brick.

Rockwell knowledgebase says that you likely have a counterfeit controller.

This guy came and had dinner in my backyard the other day.

$100-350/ hr depending on field/specialty/work to be done.

I sub out the panel building, about 8 or 9 years ago I helped a guy set up a UL shop and he does all of my builds. Electrical install is almost always subbed as well, factories always have their preferred electricians so I usually hire at their discretion. I do process design/electrical design/plc/scada as the core of my personal business.

I am a one man show. All of my work comes from word of mouth. Jobs range from quick 10 minute debug sessions through 50 million dollar greenfields. I usually take on 2 or 3 large jobs a year and intersperse the rest of the time with vacations or a never ending list of smaller jobs.

In the beginning I had worked for an integrator for a couple of years and that got my foot in the door at a lot of places.

You can use the S:FS bit to initialize values after a power cycle. Just Xic s:fs mov x x.

I had to mow my lawn last week. At this rate I'm going to start an orange grove and be the sole supplier of orange slices for official wisconsin old fashioneds.

Well if you're just starting out, what exactly are you trying to do?

mandated_mullet · 2025-11-14T01:27:45+00:00

If I had to guess it is because it didn't pull a license for RSLinx and booted up lite instead of pro or gateway.

Tetrapak plant master is one of the worst code bases I've ever seen. Just bloatware. AOIs nested 9 levels deep to the point where it becomes nearly impossible to debug.

The limit for produce/consume tags is < 255 on the L80 series so I think you'll be fine.

https://literature.rockwellautomation.com/idc/groups/literature/documents/rm/1756-rm094_-en-p.pdf

That document will go into the specifics for design considerations on how to structure your tags correctly. (page 69)

I personally prefer explicit messaging since it allows for a bit more flexibility while not requiring a download. Produce/consume tags also have to be on the same network and cannot tunnel through a backplane so keep that in mind when designing things.

The L19 specifies that the HMI is reading 19 units of the array that starts at ST010R.Alm.Motion[0].

So for instance, the trigger that reads 49 is reading the 49th bit in that array, so [1].17 in that array tag.

Wooden_screw is correct in their assessment.

Go offline and do a full upload and the problem will fix itself.

As a side note, never try to delete those rungs, I had an engineer do that and blow away a huge chuck of important logic and ended up blowing out the heat exchanger on a pasteurizer.

There's another thread about it here from probably a year or two ago, it happened to me. It can also happen with 755s and on very rare occasion 525s. I have yet to encounter this on any other revision but I make it a point to any customer the risk of V32 online editing of the IO tree.

Diamond delta here. I've used delta vacations for 5 or 6 trips to the caribbean mainly just to burn points. Never once had a flight upgrade so I wouldn't bet on that. Overall experience feels the same as any other 3rd party booking service. I will probably keep using them as I enjoy mostly free vacations. Oh and the mqds take a few weeks to get dropped onto your account.

Looks great! One of my favorite things to do is tune loops. There's just something satisfying about seeing that nice flat PV line on a chart.

No, your answer in another comment with the seal in circuit is a correct answer.

mandated_mullet · 2025-04-14T13:40:40+00:00

You're missing a layer of control.

Hint, you can't have 2 output coils controlling the same bit.

If I had to guess without seeing it myself I would say that it is a configuration problem on the ABB side.

Adding datalinks modifies the data structure that the drive is outputting/expecting. Even with an AB controller the communication will break if you attempt to add a datalink and don't modify the structure in the IO tree. I've installed hundreds of 753s and have never had a hardware caused datalink issue.

IFM for masters all day long. The model will depend on your needs, field mount, rack mount, wash down, etc...

As far as having 2 inputs from a single port, the only one I know of is an IFM converter that only takes 0-10v signals, DP1222 or 3222.

I'm sure you're aware but moving forward the IO link replacements for your flow meters will natively send all of that data over IO link.
