About the technology
PLC control logic
Structured Text is a high-level programming language for programmable logic controllers. It belongs to the IEC 61131-3 family and expresses sequences, conditions, calculations, state machines and reusable function blocks in a readable text format. It is widely used when automation logic becomes too complex for ladder diagrams.
Automation applications
Companies use Structured Text to control production lines, robotic cells, packaging equipment, motion systems and process plants. It can coordinate sensors, actuators, safety-related states and operator commands while supporting precise timing and repeatable machine behavior.
- Sequence control for machines and production cells
- Motion and positioning logic
- Recipe, batch and process handling
- Alarm, interlock and fault-recovery routines
IEC 61131-3 ecosystem
Strong specialists work with IEC 61131-3 concepts such as programs, function blocks, functions, tasks and data types. Depending on the control system, their tooling may include Siemens TIA Portal and SCL, CODESYS, TwinCAT, Rockwell Studio 5000 or vendor-specific PLC environments. They also understand industrial networks and HMI integration.
When expertise matters
Freelance support is useful when a company is commissioning a new machine, modernizing legacy PLC logic or integrating equipment from several suppliers. Germany-based projects may require on-site commissioning, while design, testing and documentation can often be completed remotely. Clear technical English or German helps teams coordinate with plant staff and contractors.
- Reworking unclear or duplicated control logic
- Connecting PLC programs with drives, robots or HMIs
- Testing sequences before site commissioning
- Documenting code, alarms and operating states
Skills beyond programming
Effective Structured Text professionals read electrical schematics, understand machine sequences and diagnose behavior on real equipment. They can translate functional specifications into modular code, use simulation or test environments, manage source versions and create documentation that maintenance teams can follow. Knowledge of OPC UA, Profinet, EtherCAT, Modbus and industrial cybersecurity is often valuable.
Quality indicators
Look for specialists who explain their architecture clearly and separate reusable logic from machine-specific configuration. Useful evidence includes tested function blocks, commissioning records, readable naming conventions and examples of safe fault handling. Ask how they manage online changes, version control, backup procedures and acceptance tests before production handover.
Frequently asked questions
Quick answers to the questions that come up most around Structured Text.
Structured Text is used to write PLC logic for machine sequences, process control, motion coordination, recipes, alarms and data handling. It is especially effective for calculations, nested conditions and reusable function blocks that would be difficult to manage in graphical PLC languages.
Structured Text is usually more compact for calculations, state machines, data processing and complex conditions. Ladder Diagram can be easier for electricians to trace during maintenance, so many projects combine both rather than treating one language as universally better.
Structured Text specialists may work in Siemens TIA Portal with SCL, CODESYS, Beckhoff TwinCAT or Rockwell Studio 5000, depending on the control platform. They should also understand the relevant PLC runtime, fieldbus configuration, HMI environment and source management practices.
Structured Text work often benefits from knowledge of electrical schematics, motion control, industrial networks, HMI design and commissioning. Experience with Profinet, EtherCAT, OPC UA, Modbus, robotics or functional safety can be important when the PLC coordinates a complete production system.
Structured Text projects vary widely in complexity. A focused logic change may need a specialist who can work independently within an existing codebase, while a new machine or plant integration requires proven skills in architecture, testing, commissioning and fault diagnosis.
Structured Text specialists can often handle specification reviews, code development, simulation, documentation and test preparation remotely. Physical commissioning, troubleshooting on live equipment and operator training may require travel to a German production site, so the project plan should define the on-site phases clearly.
Structured Text quality is visible in modular function blocks, clear naming, consistent data types, controlled state transitions and well-documented alarms. Ask for examples of testing, version control, online-change procedures and how the specialist prevents an unsafe machine state during faults.
Structured Text is the IEC 61131-3 programming language, while Siemens SCL is Siemens’ implementation and naming for text-based PLC programming in its automation environment. The concepts overlap, but a specialist should still understand the target platform’s libraries, task model, data handling and commissioning workflow.
The average hourly rate of freelancers in Germany who have used Structured Text in their recent projects is 88 €, which corresponds to a daily rate of about 705 € based on an 8-hour working day.
Of the freelancers in Germany who have used Structured Text in their recent projects, 93% hold at least a Bachelor's degree, 64% hold at least a Master's degree, and 7% hold a doctorate.
On average, freelancers in Germany who have used Structured Text in their recent projects have 24 years of professional experience, with a single engagement typically lasting around 5.1 years.
