Online vs. In-Person Siemens PLC Training: The Real Cost Breakdown
I manage a procurement budget for a mid-sized systems integrator. Over the past 6 years, I've processed about 180—maybe 200—training requests for our engineers. The question always comes down to this: online self-paced or instructor-led in-person. Everyone wants the cheapest option. But I've seen the 'cheap' choice blow up budgets more times than I can count.
So let's cut through the marketing. What's the actual cost difference? Not just the sticker price. I'm talking about the total cost, the time-to-competency, and the hidden gotchas that hit your bottom line.
Dimension 1: Upfront Cost vs. Hidden Costs
On the surface, this isn't even a contest.
Online courses from Siemens (like their TIA Portal e-learning) run around $200–$600 per seat for a one-year subscription. A 3-day in-person class at a Siemens training center? That's typically $1,500–$2,500 per person, plus travel, plus maybe a hotel room.
So online wins, right? Not so fast.
What I mean is that the 'cheapest' option isn't just about the sticker price—it's about the total cost including your time spent managing issues, the risk of delays, and the potential need for retraining. (Should mention: we once bought a 'bulk' online subscription for $3,000. Two engineers never finished it. That's $1,500 per completion, which is more than the in-person class would've been.)
Online has a lower entry cost. In-person has a lower completion cost. If your team actually finishes the course, online is cheaper. But if they don't—which happens more than vendors admit—you're paying for nothing.
Dimension 2: Time to Competency – The Speed of Results
Why does this matter? Because time is the real currency. An engineer who's not productive is an engineer you're still paying.
Online: You work at your own pace. That sounds great, but in reality, it means a 40-hour course takes 3–6 months to finish because people get interrupted by project work. The 'cheap' option drags out your time-to-competency.
In-person: You're locked in for 3 days. That's it. They come back on Thursday morning and can actually do something. In Q2 2024, we had an urgent project deadline. I paid $2,200 for a rush in-person class for two engineers. The alternative was waiting 6 weeks for them to finish an online module. The cost of missing that deadline? $8,400 in penalties.
The question isn't 'Is in-person more expensive?' It's 'Is the price of waiting higher than the price of the class?' In that case, the answer was a clear yes.
Dimension 3: Learning Depth – Are You Getting Results or Just a Certificate?
Here's where the misconception lives. 'Online is the same content.' That was sorta true 5 years ago. Today, the gap is real.
The '[Online is just as good]' thinking comes from an era when companies tried to save money by recording a lecture. That changed. Modern online courses from Siemens actually have good simulations and interactive elements. For basic PLC programming—S7-1200 config, ladder logic fundamentals—online works just fine.
But for advanced stuff? Say, complex S7-1500 motion control or TIA Portal security (IEC 62443)? In-person wins every time. The hands-on troubleshooting, the instructor answering your specific problems, the debugging of real hardware—that's where you get the real learning.
I saw an engineer spend 3 hours online trying to figure out a Profinet communication error. In an in-person class, the instructor walked him through it in 15 minutes. That's a 3-hour savings. For a team of 5 engineers, that can be a $2,000+ savings in salary time alone.
Dimension 4: The Hidden Cost of Giving Up Control
Here's the dimension most cost analyses miss: schedule certainty.
Online means you're at the mercy of the engineer's motivation. They have to carve out time. They have to not get pulled into a fire drill. In my experience, about 30% of online learners drop off within the first month. That's a 100% waste of your investment.
In-person means the work gets done. Period. You pay for certainty. It's the same reason you pay for a guaranteed FedEx delivery instead of a 'ships when ready' option. You're not paying for speed; you're paying for the guarantee that it will happen.
I've been burned twice by 'probably on time' promises. Now, for critical skills training, I budget for the in-person option. It's basically a no-brainer for urgent needs.
Which Should You Choose?
There's no universal right answer. It depends on your situation.
Go with online self-paced if:
- You're training a large group (10+ engineers) on fundamentals
- Your team is self-motivated and proven to finish online courses
- The skill isn't time-sensitive—it's for future projects
- Your budget is tight and you can't afford the upfront cost of in-person
Go with in-person instructor-led if:
- You need an engineer productive next week
- The training is for complex or advanced topics (motion control, safety)
- Your team has a history of not finishing online courses
- The cost of delay (missed deadlines, project penalties) is high
In the end, the cheapest training is the one your team actually finishes and uses on the job. For my budget, a $1,800 in-person class that gets used is infinitely better than a $200 online course that collects dust.
