Install or program computer hardware or machine or instrumentation software in microprocessor-based systems.+
Install the new motion-control board and load its firmware into the PLC rack, wire the encoder and motor power according to the panel drawings, then commission the axes so the spindle reaches 3,000 rpm under load with no fault trips by end of shift.

Measure the clearance between the coupler and shaft on ten samples using the micrometer and feeler gauges, record each measurement with serial number, compare to the drawing tolerance and mark any out-of-spec parts for rework by end of day.

Establish and maintain inventory, records, or documentation systems.+
Create and update the spares ledger with current stock, part numbers, locations and minimum levels, attach the latest purchase receipts, and produce a one-page reorder list for procurement to action before Monday.

Operate metalworking machines to fabricate housings, jigs, fittings, or fixtures.+
Set up the job to fabricate five motor housings and two alignment jigs: produce the step‑by‑step machining plan, specify stock sizes, cutting speeds, tooling list, tolerances and finish, schedule machine time with the shop foreman and record setup parameters after first part run.

Identify energy-conserving production or fabrication methods, such as by bending metal rather than cutting and welding or casting metal.+
Survey current fabrication processes and identify three energy‑saving changes, prioritising bending over cutting/welding where possible: estimate material, energy and labour savings, check compliance with banned‑materials rules, and produce an implementation plan with payback times for the operations manager within two weeks.

Can AI actually do this job?

the honest answer

It can

where it genuinely helps
  • Explain the theory behind the work
  • Draft, tidy and structure your writing
  • Rehearse a hard conversation before you have it
  • Build a study plan that fits your gaps

It cannot

where it stops, completely
  • Be in the room where a plc technician actually works
  • Carry the responsibility when the call is wrong — that weight stays yours
  • Notice what no one wrote down: the hesitation, the thing left unsaid
  • Live with the outcome

Questions people actually ask

You’ll split time between hands-on machines and paperwork. Mornings often start with scheduled checks: calibrate sensors, verify part dimensions with calipers, and run test sequences on automated lines or EM (electromechanical) games.

Afternoons usually go to troubleshooting faults, replacing defective electronic or mechanical parts, and updating maintenance records in Microsoft Excel or Microsoft Access. You may also help engineers test prototypes, write assembly or repair steps in Microsoft Word, and attend briefings in Microsoft Outlook.

Expect ladder-logic and device setup on PLCs through vendor programming tools, plus general tools like Microsoft Excel, Word, and Outlook for logs and reports. For design or drawings you’ll see Autodesk AutoCAD and Dassault Systèmes SolidWorks.

If you’re scripting tests or processing logs, basic Python helps. For development work on microprocessor-based systems you might encounter C++ and Linux for embedded programming and device configuration.

According to the U.S. Bureau of Labor Statistics (BLS) for 2025, 15,520 people were employed as PLC-related technicians in this SOC, with a median pay of $73,900 per year. The lowest tenth earned $47,840 and the top tenth $109,890.

Use those numbers as a range—local wages differ by industry, location, and experience, especially if you work in robotics or specialized test equipment.

Begin with basic electrical and mechanical classes at a community college or trade school — topics: circuits, pneumatics, and reading technical drawings (AutoCAD basics help). Get comfortable with Microsoft Excel and Word for documentation.

Practice on entry-level PLC kits and learn ladder logic via vendor tutorials. Add basic Python and C++ for simple scripting and embedded work, and try SolidWorks or AutoCAD to read designs. A certificate plus 1–2 years as a maintenance tech or assembler gets you in.

No. A PLC technician focuses on programming, installing, calibrating, and maintaining PLC-controlled electromechanical systems — sensors, actuators, and game or production rigs. You’ll do hands-on troubleshooting and replace parts.

A robotics technician overlaps but spends more time on robot assembly, motion testing, and actuator control; a controls engineer designs control systems and writes higher-level programs and specs, often using C++ or Python in Linux and working with engineers on environmental or statistical studies.

AI can help draft maintenance documents, analyze log data exported to Excel, or suggest troubleshooting steps based on error codes. Use it to write clear assembly instructions in Word or to parse test results produced during prototype evaluation.

Do not rely on AI for safety-critical decisions: verify all calibration, sensor settings, and code changes on the actual machine. Keep a human-in-the-loop for approval, and store final procedures and records in your official systems like Excel/Access.

Prioritize hands-on troubleshooting: electrical measurement, replacing faulty electronic/mechanical parts, and calibrating sensors/targets. Those skills fix most daily problems and let you work across EM games, unmanned systems, and production lines.

Second, learn PLC programming and basic ladder logic plus one software tool—Excel for records and reports. Knowing AutoCAD or SolidWorks helps with jigs and parts, and basic Python/C++ is valuable for embedded or prototype testing.
