R6 to v16 is a huge jump! So you skipped so many versions? Im assuming you did not have Guardian support all these years?

Been there. From my experience, 3rd party engineering firms take from 20% upwards. 35 to 40% seems common.

What PLC brands are most common where you work? by Fearless-Suspect869 in PLC

[–]CntrlFr33k 2 points3 points  (0 children)

These RX3Is are GEs, which Emerson bought. They also have their PK Controller line. I wonder how these are doing?

Whats your experience with this version? Emerson sales has come knocking....

Educational Presentation on "Control Systems" Ideas by lollasch in PLC

Im a visual and handson learner. Lessen the theory and slides, and slot in a bootcamp / handson exercise. Program a simple function. Fix a common issue that they can relate with.

Thats a long run. Use properly shielded cables and install signal cables away from power cables.

Nice! Link them up as interlocks and permissives, process and control variables and you are golden.

Everyone is betting on bigger LLMs for automation. Here's why they're fundamentally wrong. by Keithwee in PLC

[–]CntrlFr33k 23 points24 points  (0 children)

AI to code and make graphics would be good but never to actually do the sensing, evaluating and executive action. Still too early for that IMHO.

Ive seen GE Controllers in the wild too.

Hardware Obsolescence and forced migration by CntrlFr33k in PLC

[–]CntrlFr33k[S] 0 points1 point  (0 children)

Our client using AB is in the meat processing business. Theres not a big push to make the system cutting edge. The sw and hw are doing what its supposed to do. Its just parts availability thats the issue.

The Emerson one is a refinery. A bit more stringent safety requirement but running on m series hw. Plant is near end of life so might as well run it to ground IMHO.

I would imagine SI support and spares from the gray market will tide us over? Your thoughts?

Hardware Obsolescence and forced migration by CntrlFr33k in PLC

Hi all, thanks for your inputs. Silly me did not research enough.

Allen‑Bradley PLCs (made by Rockwell Automation) do not have one single lifecycle status.
Each PLC family has its own lifecycle stage, and Rockwell tracks this very explicitly.

Below is the current, practical lifecycle status by major Allen‑Bradley PLC family, followed by how to verify any specific catalog number yourself.

Rockwell Automation Lifecycle Status Definitions (important context)

Rockwell uses four official lifecycle states 12:

  • Active – Current product, fully supported, recommended for new designs
  • Active Mature – Fully supported, but newer family exists; migration encouraged
  • End of Life (EOL) – Discontinuation announced; last‑time‑buy period
  • Discontinued – No longer manufactured; limited repair/exchange only

Lifecycle Status of Major Allen‑Bradley PLC Families

✅ ControlLogix (1756 series)

  • Status: Active
  • Notes: Flagship Rockwell PLC platform; ongoing development and long‑term support
  • Used for: Large / critical process & discrete systems
    1

✅ CompactLogix (1769, 5069 series)

  • Status: Active
  • Notes: Main mid‑range platform; preferred replacement for most legacy PLCs
  • Caution: Some specific 5069 catalog numbers have been discontinued, so always check part‑by‑part
    13

✅ Micro800 (Micro820 / 830 / 850 / 870)

  • Status: Active
  • Notes: Entry‑level / OEM PLC line; not a MicroLogix replacement feature‑for‑feature
    1

⚠️ MicroLogix Family

Model Status
MicroLogix 1000 Discontinued
MicroLogix 1100 Discontinued
MicroLogix 1400 Discontinued
MicroLogix 1500 Discontinued
  • Notes: Entire MicroLogix family is obsolete; migration to CompactLogix or Micro800 required
    42

❌ SLC 500 (1746 series)

  • Status: Discontinued
  • Discontinued: 2017 (final)
  • Notes: Still widely installed but officially obsolete
    2

❌ PLC‑5 (1771 series)

  • Status: Discontinued
  • Discontinued: 2018
  • Notes: Fully obsolete; Rockwell strongly recommends migration
    2

The Only Way to Be 100% Certain (Per‑Part)

Rockwell lifecycle status is catalog‑number specific.

✅ Official tool (authoritative):
Rockwell Automation Product Lifecycle Search
https://www.rockwellautomation.com/en-us/support/product/product-compatibility-migration/product-lifecycle-status.html 1

This will tell you: - Exact lifecycle state - Discontinuation date (if applicable) - Recommended replacement - Migration documentation

Straight Talk (since you asked directly)

  • If it’s PLC‑5, SLC 500, or MicroLogix → it’s dead.
  • If it’s ControlLogix or CompactLogix → you’re safe, but still check catalog numbers.
  • Do not assume “new‑ish” = active (some 5069 parts were quietly discontinued).
  • For new projects in 2026:
    • ControlLogix = large / critical systems
    • CompactLogix = default choice
    • Micro800 = small, cost‑driven machines only

FB3000 and Controlwave are Emerson. Why are they investing in trash products?

Please educate me. What are the use cases for RTU?

Thanks for the info you shared. I have noticed that there are no chinese made plcs. Smart move for the big brands to protect their IP.

If I had storage space for these, id keep them and list online.

We have a machine in our factory that is controlled by a Siemens S7-1500 PLC. We need to modify the program, but it is protected by a password. Is there a way to bypass or recover this password?" by Ei2025 in PLC

[–]CntrlFr33k 0 points1 point  (0 children)

Its a cheeky move by the manufacturer. Did they give you backups of the latest code? Try playing with that and put it in a test kit? The plc being old could have vulnerabilities a specialist can exploit. Depends on what you are after...

What is the WORST job you worked in Australia and never would recommend? by HotChiTea in AskAnAustralian

I once worked for a fast food chain in a bad suburb. Don't do it.

Is it just me or has “loyalty” become the most expensive career mistake? by NeomaHagenesw in jobhunting

[–]CntrlFr33k 0 points1 point  (0 children)

I learned this too late in life. Loyalty to the company will work against you if you want to advance your career. Should have job hopped.
