Structured Text vs Function Block Diagram

Developers should learn Structured Text when working in industrial automation, manufacturing, or process control environments where PLCs are used, as it is essential for programming advanced control logic, mathematical computations, and data handling meets developers should learn fbd when working on industrial automation projects, such as factory automation, building management systems, or process control in sectors like oil and gas, where plcs are standard. Here's our take.

Structured Text

Nice Pick

Developers should learn Structured Text when working in industrial automation, manufacturing, or process control environments where PLCs are used, as it is essential for programming advanced control logic, mathematical computations, and data handling

Pros

• It is particularly valuable for applications requiring complex algorithms, such as motion control, batch processing, or supervisory control and data acquisition (SCADA) systems, where ladder logic or other IEC 61131-3 languages may be less efficient
• Related to: programmable-logic-controllers, industrial-automation

Cons

• Specific tradeoffs depend on your use case

Function Block Diagram

Developers should learn FBD when working on industrial automation projects, such as factory automation, building management systems, or process control in sectors like oil and gas, where PLCs are standard

Pros

• It is essential because it provides an intuitive, standardized way to implement control logic that aligns with IEC 61131-3 standards, making it easier for engineers to collaborate and maintain systems over time
• Related to: programmable-logic-controller, ladder-logic

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. Structured Text is a language while Function Block Diagram is a concept. We picked Structured Text based on overall popularity, but your choice depends on what you're building.

The Bottom Line

Structured Text wins

Based on overall popularity. Structured Text is more widely used, but Function Block Diagram excels in its own space.
