About the technology
PLC control logic
Structured Text is a high-level programming language defined by the IEC 61131-3 standard for programmable logic controllers. Its syntax resembles Pascal and supports variables, loops, functions, data structures and modular control logic. Companies use it for machine sequences, process control, motion routines, alarms and safety-related application logic.
Automation environments
Structured Text runs inside PLC engineering suites rather than as a standalone application. Common environments include CODESYS, Siemens TIA Portal with SCL, Beckhoff TwinCAT, Schneider Electric EcoStruxure and Rockwell Automation Studio 5000. Strong specialists understand vendor libraries, runtime constraints, fieldbus configuration, HMI links and version-controlled project structures.
Typical deliverables
- PLC programs for machines, production lines and process systems
- Reusable function blocks, state machines and alarm handling
- Motion, recipe, sequencing and communication routines
- HMI and SCADA data interfaces
- Commissioning documentation and tested software releases
When companies bring expertise
Companies often need freelance expertise when a new machine must be automated, an existing PLC application needs restructuring or an internal team faces a commissioning deadline. Specialists can also help migrate legacy logic, standardize reusable modules, connect drives and sensors, or troubleshoot intermittent behavior. In Germany, remote programming can work well when the site team handles physical access, while commissioning may require on-site collaboration.
Skills around Structured Text
Effective work combines Structured Text with PLC hardware selection, industrial networks and electrical documentation. Relevant adjacent skills include Profinet, EtherCAT, OPC UA, Modbus TCP, HMI configuration, SCADA integration, motion control and safety PLC concepts. Testing on a simulator or test rig, clear naming and disciplined change management reduce commissioning risk.
Signs of strong specialists
- They turn functional specifications into clear states, interlocks and fault paths
- They separate reusable logic from machine-specific configuration
- They trace variables across PLC, HMI, drives and field devices
- They test edge cases, restart behavior and communication failures
- They document assumptions and support handover to the plant team
A capable professional explains why a sequence is safe and maintainable, not only why it runs. Look for relevant experience with the target PLC family, realistic commissioning practice and concise technical documentation. German or English communication may matter depending on the site, suppliers and operating team.
Frequently asked questions
Quick answers to the questions that come up most around Structured Text.
Structured Text is used to program PLCs that control machines, production lines and process equipment. It is well suited to calculations, state machines, recipes, communication handling, motion sequences and reusable function blocks.
Structured Text is usually more concise for calculations, data processing, loops and larger program structures. Ladder Logic can be easier for electricians to diagnose visually, so many projects combine both according to the task and the maintenance team’s needs.
Structured Text is the IEC 61131-3 language family, while Siemens SCL is Siemens’ implementation and naming for text-based PLC programming. The core concepts are similar, but syntax details, libraries, diagnostics and engineering workflows depend on the PLC vendor.
A strong Structured Text specialist often also understands PLC hardware, fieldbus systems and HMI or SCADA integration. Profinet, EtherCAT, OPC UA, Modbus TCP, drive control, safety concepts and commissioning are valuable when the work spans the complete automation system.
The required Structured Text experience depends on the system’s safety, motion, networking and commissioning demands rather than on code volume alone. A small logic change may need focused PLC knowledge, while a new production cell benefits from someone who has designed, tested and commissioned comparable systems.
Structured Text programming, code reviews, simulation and documentation can often be completed remotely when project files and test access are available. Factory acceptance tests, hardware troubleshooting and machine commissioning may still require on-site work, with clear coordination between the specialist and the plant team.
Review Structured Text for clear state handling, predictable restart behavior, meaningful diagnostics and separation of reusable logic from machine-specific settings. Ask for examples of testing, version control, documentation and how faults in sensors, drives or network communication were handled.
Structured Text is commonly developed in CODESYS, Siemens TIA Portal with SCL, Beckhoff TwinCAT and other vendor environments that support IEC 61131-3. The right tool depends on the PLC platform, installed libraries, fieldbus technology, simulation options and the plant’s maintenance standards.
