Does running a large number of FC programs within the interrupt OB37 affect the processing speed of normal programs in OB1 and other interrupt routines? What impact does it have on the CPU's operation? Answer: 1. When a large number of FC programs are executed inside OB37, it can indeed influence the execution of other programs such as OB1 and other interrupts. This is because the priority of the organization block determines when it runs. In general, higher-numbered OBs have higher priority. For example, OB1 typically has a priority level of 1, while OB37 is set to level 14. This means that OB37 will execute before lower-priority blocks. 2. Regarding the impact on the CPU itself, there is no direct effect on the CPU hardware. The CPU simply follows the system’s scheduling rules. However, if too many tasks are assigned to high-priority OBs like OB37, it may reduce the overall efficiency of the system by limiting the time available for other important tasks. 3. It's more relevant to ask whether this affects the real-time performance of your control system. If OB37 is used for high-priority, time-sensitive tasks, then it's a good practice. But if it's overloaded with too many FC programs, it could cause delays in less urgent tasks. 4. A well-designed system should assign critical, real-time functions to higher-priority OBs, while less urgent tasks go into lower-priority ones like OB1. This ensures better resource management and system responsiveness. 5. While it's not ideal to run a large number of FC programs in OB37, there are cases where it might be necessary to meet strict real-time requirements. In such situations, it's crucial to optimize the code and ensure that the interrupt handling is efficient and doesn't cause unnecessary delays. Ultimately, a skilled programmer knows how to balance the use of interrupts, ensuring that the control system remains both efficient and responsive.
