About the technology
What it is
Function Block Diagram, commonly called FBD, is a graphical programming language for programmable logic controllers. Engineers and automation specialists connect function blocks to represent signals, logic, timers, counters and control sequences. The visual format makes relationships between inputs, processing steps and outputs easy to trace.
What it builds
FBD is used to create control programs for machines, production lines, process equipment and building systems. It suits applications where operators and maintenance teams need to understand control behavior without reading extensive text-based code.
- Motor, pump and valve control
- Interlocks, alarms and safety-related sequences
- Conveyor and production-line automation
- HVAC, energy and process control
Tools and skills
FBD work usually takes place in a PLC engineering environment such as Siemens TIA Portal, CODESYS, Rockwell Studio 5000 or Schneider EcoStruxure Control Expert. Strong specialists understand IEC 61131-3 concepts, PLC hardware, fieldbus communication, HMI design and industrial networking. They also work with structured text or ladder logic when a project needs a mixed-language solution.
When expertise matters
Companies bring in freelance FBD specialists when a new machine must be commissioned, an existing PLC program needs restructuring or a production system requires reliable troubleshooting. In Germany, this work often connects with manufacturing, logistics, process facilities and building automation. Remote preparation can cover logic reviews and documentation, while commissioning may require on-site collaboration.
- Review unclear or fragile control logic
- Convert functional specifications into PLC programs
- Test sequences with simulation or factory equipment
- Document blocks, signals and operating states
What professionals deliver
A capable professional turns operating requirements into clear, reusable blocks with meaningful names and defined interfaces. Deliverables may include PLC source code, hardware and I/O mappings, alarm behavior, test plans, commissioning records and operator documentation. Good practice includes fault handling, safe restart behavior, version control and disciplined change management.
How to assess quality
Look for experience with the PLC vendor and engineering environment used in the project, not just general automation knowledge. Ask how the specialist approaches signal validation, diagnostics, recovery after faults and handover to maintenance teams. A practical review of sample documentation or a discussion of a comparable control sequence can reveal whether the person creates understandable logic rather than only working code.
Frequently asked questions
What clients ask us most about Function Block Diagram — answered in short.
Function Block Diagram is used to program PLC-based control systems with connected graphical blocks. Companies use it for machine sequences, motor and valve control, interlocks, alarms, process automation and building systems.
FBD represents logic through connected blocks, which can make signal flow and reusable functions easy to follow. Ladder logic is often preferred for relay-style logic and maintenance familiarity, while structured text is better suited to complex calculations and data handling. Many industrial projects combine these IEC 61131-3 languages.
A strong Function Block Diagram specialist should understand PLC hardware, I/O configuration, HMI systems, industrial Ethernet and fieldbus communication. Knowledge of Siemens TIA Portal, CODESYS, Rockwell Studio 5000 or Schneider EcoStruxure can be important when the project is tied to a specific environment. Commissioning and technical documentation skills also matter.
The required experience depends on the control scope, safety demands, equipment variety and commissioning conditions. A small logic change may need a different profile from a full machine or process startup. Ask candidates to explain comparable FBD work, their testing method and how they document changes.
Function Block Diagram development, code reviews, simulation and documentation can often be handled remotely. Hardware testing, plant integration and commissioning may require access to the machine or site. In Germany, agree early on which activities need on-site presence and which can be completed through secure remote collaboration.
Bring in a FBD freelancer when internal automation capacity is limited, a commissioning deadline is approaching or existing PLC logic is difficult to maintain. External expertise can also help with migrations, diagnostics, documentation and independent validation before production use.
Review whether Function Block Diagram code uses clear names, consistent interfaces, sensible block reuse and explicit fault handling. Ask how the specialist tests normal cycles, abnormal signals, restart behavior and operator alarms. Readable documentation and a controlled handover are strong quality indicators.
Function Block Diagram is common in discrete manufacturing, logistics automation, energy systems, process plants, water treatment and building controls. It is especially useful where teams need to inspect visual control relationships during commissioning, maintenance and troubleshooting.
The average hourly rate of freelancers in Germany who have used Function Block Diagram in their recent projects is 92 €, which corresponds to a daily rate of about 739 € based on an 8-hour working day.
