What Does an Automation Engineer Actually Do? A Practical Guide

Industrial automation is one of the most important areas in modern manufacturing, production, oil and gas, water treatment, energy, and process industries.

But what does an Automation Engineer actually do?

Is the job only about programming PLCs? Does an Automation Engineer need to understand electrical systems? What about SCADA, instrumentation, control panels, VFDs, and industrial communication?

The reality is that industrial automation is a multidisciplinary field. An Automation Engineer needs to understand how electrical systems, control systems, instrumentation, software, and industrial equipment work together.

This guide explains what Automation Engineers actually do in real industrial environments and provides a practical learning roadmap for electrical, mechatronics, and engineering graduates who want to build a career in automation.

What Is an Automation Engineer?

An Automation Engineer is responsible for designing, programming, integrating, commissioning, maintaining, and troubleshooting automated industrial systems.

In a typical industrial environment, an Automation Engineer may work with:

• PLCs
• HMI systems
• SCADA systems
• Sensors and transmitters
• Motors and motor control systems
• Variable Frequency Drives (VFDs)
• Control panels
• Industrial networks
• Process instrumentation
• Industrial machines
• Electrical control systems

The engineer’s role is to make industrial processes operate safely, reliably, and efficiently with minimum unnecessary manual intervention.

What Does an Automation Engineer Do in a Real Industrial Environment?

The daily responsibilities of an Automation Engineer can vary depending on the industry and project.

However, several activities are common across industrial automation jobs.

PLC Programming

PLC programming is one of the core skills in industrial automation.

An Automation Engineer may program a PLC to control motors, pumps, valves, conveyors, production machines, and complete industrial processes.

Common PLC tasks include:

• Creating control logic
• Programming digital and analog inputs and outputs
• Developing sequences
• Monitoring PLC status
• Testing I/O signals
• Troubleshooting logic problems
• Modifying existing programs
• Commissioning PLC systems

Siemens PLCs and TIA Portal are widely used technologies that automation engineers may encounter in industrial environments.

For engineers starting their automation journey, understanding PLC fundamentals is one of the most important steps.

Motor Control and Classic Control

Automation does not start with PLC programming.

A strong Automation Engineer should understand the electrical control systems that existed before modern PLC-based automation.

Classic control concepts include:

• Contactors
• Relays
• Overload protection
• Timers
• Push buttons
• Emergency stop circuits
• Star-delta starting
• Direct-on-line starting
• Interlocking
• Motor protection

Understanding these systems makes PLC programming easier because many PLC control sequences are based on the same fundamental industrial control concepts.

HMI and SCADA

Automation Engineers also work with operator interfaces and supervisory systems.

An HMI allows operators to interact with machines and processes through graphical interfaces.

SCADA systems provide a higher-level view of industrial processes, allowing operators and engineers to monitor equipment, alarms, process values, trends, and system status.

A typical automation system may therefore include:

PLC → HMI → SCADA → Industrial Network → Field Devices

Understanding how these systems communicate is an important part of modern automation engineering.

Industrial Wiring and Control Panels

An Automation Engineer should not be limited to software.

Industrial automation systems depend on correctly designed and wired electrical panels.

Engineers may need to understand:

• Control panel components
• Terminal blocks
• Circuit breakers
• Contactors
• Relays
• PLC modules
• Power supplies
• Industrial switches
• Control wiring
• Signal wiring
• Cable identification
• Electrical schematics

During installation and commissioning, the engineer may also need to inspect wiring and verify that field devices are correctly connected to the control system.

Sensors and Process Instrumentation

Industrial automation depends heavily on accurate field information.

Sensors and instruments provide the PLC or control system with information about the physical process.

Examples include:

• Temperature sensors
• Pressure transmitters
• Flow meters
• Level sensors
• Proximity sensors
• Photoelectric sensors
• Position sensors
• Pressure switches
• Level switches

An Automation Engineer should understand how these devices work, how they are connected, and how their signals are interpreted by the control system.

Variable Frequency Drives

VFDs are commonly used to control the speed and operation of electric motors.

Automation Engineers may configure and troubleshoot VFDs for applications such as:

• Pumps
• Fans
• Conveyors
• Compressors
• Industrial machinery

A practical understanding of motor control, PLCs, electrical systems, and VFDs allows the engineer to build more complete automation solutions.

Troubleshooting

Troubleshooting is one of the most important practical skills for an Automation Engineer.

When a machine stops working, the engineer needs to determine whether the problem is related to:

• Electrical power
• Wiring
• Sensors
• Actuators
• PLC inputs or outputs
• PLC programming
• Communication
• HMI
• SCADA
• VFD parameters
• Mechanical equipment

This is why practical training is so important.

Knowing the theory of a PLC is different from standing in front of a real control panel and finding why an input is not changing or why a motor is not starting.

What Skills Does an Automation Engineer Need?

A successful Automation Engineer typically develops skills across several areas.

1. Electrical Fundamentals

Understanding electrical principles is essential.

You should be comfortable with:

• Voltage
• Current
• Power
• AC and DC circuits
• Protection devices
• Motors
• Control circuits
• Electrical diagrams

2. Classic Control

Learn how industrial control circuits work before moving deeply into PLC programming.

3. PLC Programming

7. Industrial Communication

Modern automation systems rely heavily on communication between PLCs, HMIs, SCADA systems, drives, sensors, and other industrial devices.

Understanding industrial Ethernet and common industrial communication concepts is increasingly important.

8. Troubleshooting

Develop the ability to diagnose problems systematically instead of simply changing components until the system works.

What Software Should an Automation Engineer Learn?

The exact software depends on the company, industry, and automation platform.

However, engineers working with Siemens automation systems may encounter:

• TIA Portal
• WinCC
• PLC programming environments
• HMI configuration tools
• Simulation and testing tools
• Industrial communication software

Software knowledge should always be combined with practical understanding of the physical automation system.

Programming a PLC without understanding the equipment it controls can create significant gaps in practical engineering skills.

Can an Electrical Engineer Become an Automation Engineer?

Yes.

Electrical engineering provides a strong foundation for industrial automation because automation systems depend heavily on electrical control, motors, protection, wiring, and industrial equipment.

An Electrical Engineer can build toward automation by developing additional skills in:

Electrical Engineering
→ Classic Control
→ PLC Programming
→ HMI
→ SCADA
→ Instrumentation
→ Industrial Networking
→ Troubleshooting

Mechatronics and control engineering graduates can follow a similar path.

Can a Fresh Graduate Become an Automation Engineer?

Fresh graduates can enter the automation field, but academic knowledge alone may not be enough for many practical industrial responsibilities.

The biggest gap for many new engineers is hands-on experience.

A graduate may understand what a PLC is but still have limited experience with:

• Connecting real I/O
• Wiring control circuits
• Testing sensors
• Troubleshooting PLC inputs and outputs
• Building control panels
• Configuring HMIs
• Commissioning equipment
• Diagnosing industrial faults

Practical laboratory training can help bridge this gap by allowing engineers to work with real industrial components and realistic control systems.

Theory vs. Hands-On Training: What Actually Matters?

Automation is a practical engineering discipline.

Books and courses can explain how PLCs, sensors, motors, and control systems work. However, engineers also need opportunities to apply that knowledge.

Hands-on practice allows you to experience situations such as:

• A sensor providing an incorrect signal
• A PLC input not responding
• A motor failing to start
• A communication connection failing
• An incorrect control sequence
• A VFD parameter problem
• A wiring fault

These situations develop troubleshooting skills that are difficult to acquire through theory alone.

This is why practical industrial laboratories can play an important role in automation training.
