Function Block
A Function Block is a basic building block used in industrial automation programming. Think of it like a pre-made recipe that tells machines how to perform specific tasks. Instead of writing complicated instructions from scratch, automation engineers use these ready-made blocks to create programs for manufacturing equipment, assembly lines, or automated systems. It's similar to using building blocks in a construction set - engineers combine different Function Blocks to make machines work together. This approach is common in systems like Siemens PLC, Rockwell Automation, or Schneider Electric equipment.

Example Interview Questions
Senior Level Questions
Q: How would you manage a library of custom Function Blocks across multiple projects?
Expected Answer: A strong answer should discuss standardization practices, version control, documentation methods, and how to ensure consistency across different manufacturing sites or projects. They should mention testing procedures and training other team members.
Q: Explain how you would troubleshoot a complex system using Function Blocks?
Expected Answer: Look for answers that demonstrate systematic approaches to problem-solving, using monitoring tools, understanding signal flow between blocks, and experience with different automation platforms.
Mid Level Questions
Q: What considerations do you take when creating a custom Function Block?
Expected Answer: They should mention user-friendliness, error handling, input/output parameters, documentation, and testing procedures. Understanding of industry standards is important.
Q: How do you ensure Function Blocks are working correctly in a safety system?
Expected Answer: Should discuss testing procedures, certification requirements, documentation needs, and understanding of safety standards and regulations.
Junior Level Questions
Q: What is a Function Block and why are they used?
Expected Answer: Should explain that Function Blocks are pre-programmed units that perform specific tasks in automation systems, making programming easier and more standardized.
Q: Can you describe the basic parts of a Function Block?
Expected Answer: Should mention inputs, outputs, internal logic, and how Function Blocks connect to each other in a program.
