I am utilizing the FM350-1 with the S7 315-2DP PLC to count encoder pulses for accurately cutting a crossing plate at a specified position. However, I have noticed that the precision of the results is not satisfactory. Would implementing an interrupt in the FM350-1 enhance the response time? If that's the case, I would appreciate any guidance on the best approach. Additionally, do you have any other recommendations to improve the overall performance?
For assistance, you may find valuable information in the thread linked above. Could you please specify the urgency of your response for optimal accuracy? Best regards,
Implementing an interrupt in the FM350-1 can definitely help enhance the response time for counting encoder pulses, as it allows your system to process inputs more efficiently without delays. To set it up, you’ll want to prioritize your interrupt servicing routine so that it captures the pulses with minimal latency. Additionally, you might also consider optimizing your PLC's scan time or using high-speed counters if they're available, as this can significantly improve the accuracy and reliability of your measurements. Setting proper debounce logic for the encoder signals can also help eliminate noise and erroneous counts. Don't forget to test your setup under different conditions to ensure it's robust before finalizing your approach!
