You Think You’re Saving Money by Skipping Training? I Did Too.
When I first started managing PLC procurement for our mid-sized automation company, I made the same mistake a lot of people make. I looked at the price tag of a CompactLogix controller—say $2,800—and then looked at the training course: $1,500 per person for a 3-day class. My budget said skip the class, buy the hardware. We’d figure out the programming ourselves.
That was early 2021. By mid-2022, I had a spreadsheet that told a very different story. It took me 18 months and four separate incidents to understand that the real cost of a PLC isn’t the purchase price—it’s the lack of training that follows.
The Surface Problem: Training Cost vs. Hardware Cost
If you’re like most procurement folks in the automation space, you’ve probably done the same math. A Micro850 costs around $400. A ControlLogix L73 is roughly $6,500. Official Rockwell Automation training for RSLogix 5000? That’s another $2,000-3,000 per student. When budgets are tight, training looks like the easiest line item to cut.
I remember sitting in a review meeting in Q4 2021, defending my decision to defer three training slots. “We have our lead programmer,” I said. “He’s been doing this for years. We can self-train the new guys.” That assumption turned out to be way more expensive than any course.
What I Missed (and What You Might Be Missing)
The problem isn’t the hardware cost—it’s the downtime cost and the rework cost. Here’s what I learned the hard way:
- Programming errors from lack of training: Our team misused Add-On Instructions, causing a batch process to mis-trigger. Result: 8 hours of line downtime, lost production worth ~$12,000.
- Incorrect safety logic: Without proper safety PLC training, a safety-rated input was wired to a standard input. OSHA near-miss. Investigation cost $3,500 in consultant fees plus three days of lost supervisor time.
- Inefficient code: The maintenance team couldn’t read the program when the original programmer left. Recoding took 60 hours at $75/hour—$4,500.
The Deep Cause: It’s Not About Training—It’s About Competency Gaps
The real issue isn’t that training is expensive. It’s that the competency gap between a trained and an untrained programmer is massive, and the gap shows up in every part of the lifecycle: commissioning, troubleshooting, and scaling.
After 6 years of tracking every invoice related to PLC projects in our cost tracking system, I found something surprising. About 35% of our annual “PLC-related costs” weren’t hardware or software—they were fixes caused by inadequate training. That number was even higher in the first two years when we didn’t require certification.
I built a simple TCO calculator after those early mistakes. The formula ended up being:
Total PLC Cost = Hardware Cost + Training Cost + (Downtime Cost + Rework Cost + Maintenance Cost)
The “downtime + rework + maintenance” bucket was almost always 4-8x larger than the training line item. Skipping training to save $1,500 often cost us $6,000-12,000 in the same year.
The Cost of Not Fixing This
Let me give you a concrete example from Q2 2022. We had a new integrator program a ControlLogix system for a critical packaging line. They had “10 years of PLC experience” but no formal Allen-Bradley certification. During commissioning, a routine function block misconfiguration caused the robot to crash into the guard. The hardware damage was $2,800. The production lost that day was $18,500. The rewiring and reprogramming took three more days.
Total: over $25,000. That’s more than enough to send every technician to a full Rockwell training course with travel expenses.
And it wasn’t a one-off. We audited all projects from 2020-2023 and found that projects led by formally trained programmers had 60% fewer post-commissioning change orders. The ROI on that training investment? About 8:1.
The Fix: Prevention Over Cure (and It’s Cheaper Than You Think)
Here’s what I finally did, and what I recommend to anyone managing Allen-Bradley PLC budgets:
- Make training a prerequisite – Not optional. Our procurement policy now requires proof of Rockwell certification (or equivalent) for any contractor handling safety or critical controls.
- Use the 80/20 rule – Focus training on the most common pain points: RSLogix 5000 programming, safety instructions, and HMI integration. You don’t need every course, just the ones that prevent the biggest failures.
- Add a verification step – Before commissioning, have a second trained technician review the program. That 2-hour review has saved us an estimated $8,000 in potential rework so far.
I’m not saying you should never skip a class. But if you’re making that decision based purely on the upfront cost, you’re probably leaving a lot of money on the table. I wish someone had shown me that spreadsheet in 2021.
(For what it’s worth, the Allen-Bradley official training portal has a handy ROI calculator. I plugged in our numbers after the fact—the result was sobering.)
Bottom Line
5 minutes of training verification can save 5 days of correction. Investing in proper Allen-Bradley PLC training isn’t a cost—it’s the cheapest insurance you’ll ever buy. If you want to keep your automation budget under control, start by spending more on the people who operate the hardware, not just the hardware itself.
