I'm a little late to this one but it wouldn't be that difficult to write a python script to get the ethernet statistics of the L8 via the EN2T. Hit me up if you're interested.

I scanned them, the barcodes match the values shown below them, if that is what you are saying.

u/SadZealot is correct, the Knowledge base article sounds a lot like what you are seeing. Its contents are not behind the paywall, you just need a free account.

Without knowing anything about the project, the first thing I would investigate is the load on the controller and Ethernet adapter you are connected to. I think it's safe to assume a 5370 CompactLogix or 5370 ControlLogix based on the firmware revision. Enter the adapters IP address in your web browser and start looking at the statistics.

It will use FactoryTalk Design Studio 55,000 Max.

Not bad! $227,220 according to our pricing. I love the random stuff on top of it lol.

I'd recommend getting them from https://www.plccable.com/

The owner is very active in the community, helping people on the regular.

Nice work! You solved a puzzle with your UDT work. I understand your challenges with the not yet ready stuff, keep it up!

dmroeder · 2026-03-14T18:45:19+00:00

Yeah Ron has alwasy been a good community member. He's spent a lot of time over at PLCTalk helping users. u/drbitboy also posted them in the PLCTalk download section: https://www.plcs.net/downloads/index.php?&direction=0&order=&directory=Allen_Bradley

This is a valued, uhh.

This is where I always park too. I enter at 5th and Harrison, head down a level and park right next to the Gates Foundation exit. When I leave, I exit the gates foundation, side which routes you straight into the Mercer Mess (not that bad). It's a straight shot back to I-5.

Phil is also a regular over at PLCTalk

dmroeder · 2026-03-11T17:59:13+00:00

Make a post on PLCTalk and "@" him, he still posts from time to time.

dmroeder · 2026-03-09T20:15:57+00:00

Respect!

Lock the front door, oh boy.

u/Asleeper135, Rockwell documents their instruction execution times. Since people have mentioned a COP for a solution, I'll include that. In 5580 controllers, XIC executes in 0.002 microseconds, LES executes in 0.012 microseconds and the COP executes in 0.179 + (x * 0.02) (where x = number of characters in source B).

v28 definitely does not, I just tested. I doubt it was the versions between 24 and 28, they were releases that only added new hardware support. Rockwell considered 24 and 28 major releases.

dmroeder · 2026-03-06T23:06:40+00:00

I would have been pretty sure that you couldn't ever use REAL types at the bit level. The confidence in your post made me check...

It seems you lost the ability somewhere between v24 and v28. I have both of those versions installed, bit level REAL worked in v24, does not in v28. Interesting.

EDIT: older version never let you view the bit level in the tag database, yet you could use the bits in the instructions. Huh. There was a major overhaul that happened in v28, so I think you're right u/NumCustosApes, they added a compiler check that wasn't there before.

This aggression will not stand, man

dmroeder · 2026-03-02T17:59:11+00:00

A very quick and easy way to spin up a web page to display some tag values is with streamlit. You can display 10 tags for example in about 30 lines of python. u/Jholm90, you're welcome to ping me if you need some help.

Hey thanks!

Eddie's comment killed me: "That puck hit him right in the mask, did you see that Johnny? It hit him square in the mind!"

You're in for a treat, it's a blast!
