PLC Platforms

Getting Started

Entry Point: Most PLC programmers start with one platform (usually Allen-Bradley or Siemens), then expand. Manufacturer training is essential—each platform has unique software and programming methods.

First Steps: Choose based on local job market. Allen-Bradley dominates US manufacturing; Siemens in process industries; Mitsubishi in smaller shops. Take manufacturer's basic course.

Key Insight: Once you master ladder logic on one platform, concepts transfer—but each has quirks. Employers value multi-platform experience.

Prerequisites

• Foundation: Basic electrical concepts, understanding of industrial systems
• Logic: Sequential thinking, troubleshooting ability
• Computer: Comfortable with Windows software, file management

Manufacturer courses assume no prior PLC experience—they teach from basics.

Timeline

• 1-2 weeks: Basic platform certification (RSLogix, TIA Portal)
• 3-6 months: Productive on one platform
• 1-2 years: Proficient in 2-3 platforms
• 3+ years: Multi-platform expert, can work across brands

Reality Check: Most programmers master their first platform within 6 months.

Time Investment

Allen-Bradley: 1-2 weeks basic course, ongoing advanced training

Siemens TIA Portal: 1 week basic, 1 week advanced

Mitsubishi: 3-5 days GX Works training

On-the-Job: 3-6 months to become fully productive

Continuing Education: 40-80 hours/year for new platforms

Costs

Allen-Bradley Training: $2,000-$3,500 per course

Siemens: $2,500-$4,000 per course

Software: Often employer-provided; student versions $100-$500

Tools: $500-$1,500 for laptop, multimeter

ROI: Multi-platform programmers earn 20-30% premium

Equipment & Tools

• Laptop: Windows-based, 16GB RAM for programming software
• Software: RSLogix (employer license), TIA Portal (Siemens, free trial)
• Hardware: Training PLCs often provided by schools/employers
