About the technology
What FBD is
Function Block Diagram, commonly called FBD, is a graphical programming language for programmable logic controllers. It represents control logic as interconnected blocks, making signal flow, conditions and data processing easier to review than purely text-based code. FBD is standardised within IEC 61131-3.
Where it runs
FBD is used in machine controls, production lines, process plants, building systems and energy equipment. It can coordinate sensors, actuators, drives, safety-related signals and operator interfaces. In Germany, it appears across manufacturing and industrial automation environments where clear, maintainable PLC logic is essential.
Ecosystem and tools
Professionals work with PLC programming suites, engineering workstations, simulation tools and industrial networks. The surrounding stack may include Siemens TIA Portal, CODESYS, Beckhoff TwinCAT, Schneider Electric environments, PLCopen libraries, OPC UA and fieldbus technologies. Strong specialists understand how FBD blocks interact with hardware configuration and HMI systems.
Typical project work
- Translate functional specifications into FBD control sequences
- Create reusable function blocks for machines and process units
- Connect PLC logic with sensors, drives, valves and HMIs
- Test sequences through simulation, commissioning and fault handling
- Document interfaces, alarms, operating states and maintenance logic
When expertise matters
Companies bring in freelance FBD specialists when a new machine must be automated, an existing PLC program needs modernisation or an urgent commissioning phase requires additional capacity. They also help standardise libraries across plants, migrate logic between control environments and diagnose intermittent faults. Remote work suits design, documentation and code reviews; commissioning and site acceptance often require on-site collaboration in Germany.
What good specialists bring
A strong professional combines graphical PLC programming with practical automation knowledge. They read electrical diagrams, understand sequencing and state machines, work safely around industrial equipment and communicate clearly with electricians, production teams and project leads. Look for disciplined naming, modular blocks, defensive fault handling, traceable testing and documentation that another team can maintain.
Frequently asked questions
What clients ask us most about Function Block Diagram — answered in short.
Function Block Diagram is used to create graphical control logic for PLC-based machines, production lines and process systems. Specialists connect blocks for timers, counters, calculations, comparisons, sequences and device signals to describe how the system should behave.
FBD presents logic as connected functional blocks, while Ladder Diagram resembles relay circuits and Structured Text uses a text-based programming style. FBD is often effective for signal processing, reusable logic and systems that benefit from visible data flow, but the best choice depends on the control task and team standards.
A strong Function Block Diagram specialist usually understands PLC hardware, electrical schematics, HMI configuration, industrial Ethernet and fieldbus communication. Experience with IEC 61131-3, PLCopen libraries, OPC UA, drives and commissioning is also valuable.
The right level depends on risk, system size and the project phase. FBD work for a small machine retrofit may need a specialist focused on implementation, while a plant-wide standardisation or safety-critical commissioning project calls for deeper experience with architecture, testing, documentation and fault analysis.
Function Block Diagram design, reviews, simulation and documentation can often be handled remotely from Germany or elsewhere. Hardware integration, machine testing and commissioning may require planned site visits, secure access to engineering systems and close coordination with the on-site team.
Manufacturing, packaging, food processing, logistics, energy, water treatment and building automation commonly use FBD. It is useful wherever PLC logic must coordinate sensors, actuators, drives, process values and operator commands.
Review whether the FBD logic is modular, readable and consistent with the hardware and functional specification. Ask for evidence of simulation or commissioning tests, clear alarm handling, meaningful block names, version control and documentation covering normal, abnormal and recovery states.
Before taking on a Function Block Diagram assignment, clarify the PLC platform, programming environment, IEC 61131-3 conventions, existing code standards and access to test hardware. Also confirm commissioning responsibilities, safety boundaries, language expectations and whether the work is remote, on-site or hybrid in Germany.
