How to Configure Interrupt OBs?

The Siemens S7 series of industrial PLCs provides a robust platform for programming and monitoring logical operations to control an endless variety of processes and equipment.

In this course, we demonstrate the use of special program blocks, called interrupt organization blocks to help control the flow of logic in the PLC and we introduce you to the most commonly used interrupt OBs.

How to Configure Interrupt OBs?
  • 1. What is an Interrupt OB?

    In this video, you will learn how the PLC program flow is controlled using the main cyclic program OB, OB1, and the use of various types of interrupt OBs and you will also learn that different PLC models may have different available interrupt OBs.

  • 2. What is a Cyclic Interrupt OB?

    In this video, you will learn the configuration of a "Cyclic Interrupt OB" and how it is implemented in two different S7 PLC models using a simple programming example and the S7-PLCSIM simulator.

  • 3. What is a Time-of-Day Interrupt OB?

    In this video, you will learn the configuration of a Time-of-Day Interrupt OB and how it is implemented in two different S7 PLC models using a simple programming example and the S7-PLCSIM simulator.
