About the technology
What Sequential Function Chart means
Sequential Function Chart, commonly called SFC and closely related to Grafcet, is a graphical method for describing sequential control logic. It represents a process through steps, transitions and actions, making machine states and operating order easier to review. SFC is standardised within IEC 61131-3 and is used in PLC programming for processes that follow defined stages.
Where SFC is used
SFC fits automation tasks where equipment must move through controlled states and respond to conditions in a known order.
- Machine cycles with start, run, pause and fault states
- Batch processes with phases, recipes and interlocks
- Assembly, packaging and material-handling systems
- Commissioning sequences for industrial equipment
- Recovery logic after stops, alarms or operator intervention
Ecosystem and tooling
SFC specialists work across IEC 61131-3 programming environments, including CODESYS, Siemens TIA Portal, Schneider Electric tools and other PLC platforms that support sequential logic. They combine SFC with Ladder Diagram, Structured Text and Function Block Diagram when a complete control application needs different programming styles. HMI design, fieldbus communication, safety systems and version control often form part of the surrounding work.
When companies bring in specialists
Companies usually seek freelance expertise when an existing sequence is difficult to maintain, a new machine needs a reliable control concept or a production line must be adapted without disrupting operations. Typical assignments include translating process descriptions into steps and transitions, refactoring legacy Grafcet logic, testing edge cases and preparing clear documentation. In Germany, collaboration may involve remote programming alongside on-site commissioning at a plant.
What strong professionals deliver
Strong SFC professionals begin with the process, not the diagram. They clarify operating modes, permissives, interlocks, timeout behaviour, manual controls and fault recovery before implementing the sequence. Their work separates normal flow from exceptional states and keeps actions deterministic, traceable and understandable to operators and maintenance teams.
- A documented state model linked to real equipment behaviour
- Tested transitions, interlocks and restart scenarios
- Clean integration with PLC, HMI and safety concepts
- Maintainable code that matches the chosen vendor environment
Evaluating project fit
Ask candidates to explain how they would model a sequence with parallel branches, aborted cycles and a controlled restart. Review examples of commissioning notes, test procedures and alarm handling rather than diagrams alone. The right specialist understands both the formal SFC structure and the practical limits of sensors, actuators, PLC scan behaviour and plant operations.
Frequently asked questions
Everything clients usually want to know about Sequential Function Chart, in one place.
Sequential Function Chart is used to model processes that move through defined steps based on transition conditions. Companies apply SFC to machine cycles, batch operations, packaging lines, assembly cells and other PLC-controlled systems where sequence visibility and fault recovery matter.
Sequential Function Chart shows process flow directly through steps, transitions and actions, while Ladder Diagram is often useful for relay-style logic and Structured Text suits calculations or complex algorithms. Many control applications combine these IEC 61131-3 languages instead of choosing only one.
Grafcet is the formal method that strongly influenced Sequential Function Chart, and the terms are often used together in industrial automation. SFC is the IEC 61131-3 programming representation, while Grafcet may refer to the modelling notation or specification approach used before implementation.
A strong Sequential Function Chart specialist usually understands PLC programming, HMI and SCADA integration, industrial networks, safety interlocks and commissioning. Knowledge of Ladder Diagram, Structured Text, Function Block Diagram and vendor tools such as CODESYS or Siemens TIA Portal is also valuable.
Sequential Function Chart work for a small, well-defined sequence may need focused implementation and testing support. Complex machines, batch systems or production lines require a specialist who can analyse operating modes, parallel paths, alarms, recovery states and on-site commissioning constraints.
Sequential Function Chart design, code review, documentation and simulation can often be completed remotely using shared specifications and controlled access to the automation environment. On-site time may still be needed for commissioning, sensor checks, safety validation or production trials, so travel and German or English communication should be agreed early.
Review whether Sequential Function Chart logic clearly defines every operating mode, transition condition, action and fault response. Ask for evidence of simulation, test cases, restart behaviour, alarm handling and documentation that maintenance staff can follow without relying on the original specialist.
Sequential Function Chart implementation stays maintainable when steps have clear names, transitions express one understandable condition and actions do not hide unrelated logic. Consistent state handling, documented interlocks, reusable patterns and alignment with the PLC vendor's conventions make later troubleshooting and expansion safer.
