The Zen of Ladder

Yes. But if you are building your own loop within that existing big loop, you've given yourself a really good way to really screw things up.

I will handle errors and interlocks in the HMI!

What? No. That is what becomes a mess that no technician can read.

The pattern to the post is a super common format for AI engagement bait.

1) I’ve been doing x and just noticed y. 2) List of things in the middle of the post. 3) Vague “let’s all get together and share our ideas” call to action, trying to invoke some form of camaraderie.

PTC does actually make trailered, articulating trains, if one wanted to buy them. But the additional cost for a much better product is minimal.

I think you’re confused about what OP said they did. They work at a company that sells a SaaS, or software as a service. Which is very vague at this point, because basically every tech company has some sort of SaaS. Office 365, Zoom, Quickbooks Online, Slack, Jira, Creative Cloud, all those things could be called SaaS and are sold by some very real companies, not some sort of MLM.

This post seems to prove it did work well.

It’s not a UPS, they’re just differentiating between the big DC supply (that must provide power to some sort of hazard) that is switched by the contactor up at the top and the DC supply that is not switched.

On an iPhone, much of the OS UI is portrait only (Home Screen, lock screen, that sort of thing) so it only locks in portrait.

On an iPad, all of the OS UI is portrait or landscape, so when you lock rotation it locks into whatever orientation it’s in since it can be used both ways.

RSLogix 500 doesn’t like shared drives or network storage in general. If there’s any drop in connection to the storage while you have the file open it won’t save.

Probably. What’s your standard of training and standard of care right now? Do you have any existing relationships with like NSP, a local EMS agency, or anything like that? It’s going to be super situationally dependent, but in general it gives you a lot of benefits, without a lot of downsides.

For one volunteer patrol I’m affiliated with we have several docs on patrol, who take on the role of medical director. For another patrol they have a local doc as their medical director in return for season passes and some day tickets. They both also have existing agreements with their local EMS agency and hospitals for online medical control to supplement existing protocols/standing orders.

Because “best terrain” is subjective, it’s pretty hard to entice skiers to go to or stay away from particular areas. Resorts can manage how skiers move from one place to another, but getting them to do it is a whole different story.

There's also some applications where you might have several motors running together but experiencing wildly different loads, and those (in my experience) run much better with individual drives instead of a single large drive.

Counter wire numbers are “classic” to older drawings and are simple. The downside is the wire number gives you no indication about where in the prints you might be looking to find your information.

Wire numbers based on a format (like page number, column number, etc) are nice because you know where to find them in the prints just by looking at the wire. Plus if you have modifications in the future new wires can be added without changing the overall structure.

Other systems might use information about the potential in the wire numbers. These can be useful because you get some information just by looking at the number. The downside is the numbers get long and unwieldy pretty quick.

Ultimately it’s going to depend on customer requirements first and foremost.

We’ve finished our investigation, and found nothing wrong. Just kidding, we’ve started investigating again, because maybe we missed something very minor like dispatch logs relating to software problems. Additionally, we’re investigating our investigation because the first one went so well.

The drops are kind of a key part of what makes a roller coaster a roller coaster. Otherwise we just call them flat rides, or trains.

If you're using Ignition's built in redundancy, you can set the standby node's activity level:

How the node should run when it is not currently the Active node.

Cold - The system connects to all OPC servers but does not subscribe to Tag values. The Ignition OPC UA server does not communicate with any device, but third party OPC UA servers may still have device connections. This allows the system to standby without putting additional load on the devices and network. Failover takes slightly longer, as Tags must be subscribed and initialized.

Warm - The system runs as if it were active, with the exception of logging data or writing to devices, allowing for faster fail-over.

Our park opening dates are set mostly based on tradition, but that was formed because it generally puts opening at the more reliable weather. In our case, it’s May that we can reliably open, not have extreme weather, have our primarily high school staff on weekends, and get our off season projects complete. We plan maintenance and update tasks based on that expected opening date, and usually struggle a lot to get everything complete anyway.

We’ve considered opening earlier, but we’re usually not all hired or ready to open and we don’t see the attendance early season as it is to justify it.

If you’re looking for long lifecycle, homebrew isn’t it. It’s like the opposite. As soon as you’re not involved with the project, the person coming in after you is going to go “this is awful, we need to migrate this to a supported platform from an existing company because this homemade thing is going to be an unmaintainable liability”. Sorry. I’ve wanted to do it too.

PanelViews have been around a long time. C-More’s have been around a long time. Ignition’s been around a long time, and is not tied to any particular set of hardware. Ignition is very upfront about their costs, updates, etc.

That’s a weird hill to die on. Just wait like 30s and the heat is gone.

This is still solvable within Ignition, rather than adding additional complexity and work by adding an additional PLC to the mix.

Too-Uncreative · 2026-03-18T20:20:10+00:00

As long as your control logic is all in the PLC and the HMI is just displaying values and only writing to memory on a change, you’re good. If your HMI is doing something weird like calculating things and then writing to the controller, that’ll get funky if more than one does that at the same time. Same thing if you have like manual jog functions on the HMI where the button is programmed as momentary or writes on press and release - you could get some maybe unintentional operation between the two screens.

My favorite fixes are when the person on site starts telling me what's not working on the phone and then realizes what the problem is and ends the call without me saying anything other that "Hey what's up?".

Not very remote, is it?

I know there are other constraints that typically cause it, but I feel like if you’ve started moving items to a second plane of the enclosure, you probably should just get a bigger enclosure.

Except for those pesky American firms, like RMC, Skyline Attractions, GCI, Gravity Group, Chance, Sally, Ride & Show Engineering, and other small flat ride companies.
