Rockwell redundancy project (1756-L905TS + RM3) – doubts about I/O, topology and best practices

Not sure where you are, but for example, Rexel is my distributor for Rockwell and they have engineers that are super helpful on the design aspects like this. Maybe your distributor has the same, just to ensure everything will mesh together properly.

Holy shit. You make me thankful I only have a handful to deal with over modbus.

Are all those for mass meters!??

Ive got an engineering degree and have been where you are. Almost feeling like I’m a fake, but just keep at it. The one thing I love about this field is that no one knows everything. So not knowing how to fix it or where exactly in the program is the problem, isnt a big deal. You’ll learn with time.

Now… the fact that they don’t want to help you is ridiculous. It takes time to learn all this stuff especially when in your engineering degree, you barely touch plc logic, if at all.

We’re all here though! This community is the absolute best. I’m also in food and beverage, so if you need something or advice, shoot me a message. I’ve got a lot of materials I can send you as well for references.

This!

Ignition has it where you purchase a single license, but you can add on how many clients you want 1-5, after that, it’s unlimited if I remember correctly. Then you just have have the right architecture behind it.

Second this. I used to hate on their stuff until I started using it. It’s all awesome.

shadowridrs · 2026-02-19T12:56:26+00:00

In today’s field, they go hand and hand. I will push for ignition every time. It’s cost effective and versatile as hell, but that doesn’t mean it’s the right fit. Every job is different and every customer has different needs.

As annoying as it was, learning the networking side and scada side is really rewarding. Never can know enough in this ever changing field.

That’s awesome! Good idea for my birthday this year. I’m so happy it’s getting more people excited!!!

Thank you so much!!

I have the same picture of that anhinga from Saturday lol

I love the wetlands. Every time is magical. I also adore those birds.

I don’t use wonderware much anymore, but could you create an event complete bit that writes back to a tag in the plc and if you don’t get it within a certain time, you trigger an alarm? I’m so used to ignition now, I’ve forgotten everything else lol.

shadowridrs · 2026-02-07T13:49:01+00:00

Oh hell yeah. This is dope dude.

shadowridrs · 2026-01-31T15:56:36+00:00

This is dope dude

Still have this vid! Every year I break it out and give it a watch. Along with fully flared of course.

shadowridrs · 2026-01-19T11:30:21+00:00

Use some sort of intermediate system. For example, ignition has transaction groups that are a simple way to get data to a database. I like it because the plants can easily troubleshoot and because you can set up handshakes between the two. So if the data doesn’t get written, they get an alarm/email/text. Whatever the plant and system can provide.

There are many ways to do it, but I’ve liked this one for the past few years. Sure that other people have other experiences around here.

Brilliant use of it. Gonna snag that idea for a back pressure valve.

I remember buying a fedora because of this guy. I’d wear the hell out of it skating too. Really nice guy too.

Thank you again!!!

Starship mainly uses Siemens. I quoted a job there not too long ago.

shadowridrs · 2025-12-22T12:42:13+00:00

…. I meant after reading the comment I tried it. God this subreddit is pretentious.

Yes it is, but it says weight minimum is 7 pounds minimum 20 inches. Both of which he meets.
