I am experimenting with a straightforward program. I've assigned the DPLSY instruction to output Y0 and created a wire connection that routes the output pulses from Y0 back to the input at X0. Currently, I'm measuring the pulse counts on both output Y0 and input X0. When using a standard counter, I receive precise values; however, utilizing a high-speed counter (C235) to measure the input pulses at X0 results in significantly inflated values compared to the actual pulse count. For this trial, I am working with a low frequency of 20Hz. What could be causing this discrepancy?
Is the output generated by a relay or a solid-state transistor? If it's a relay, it could potentially be accounting for all the signal bounces as well. Just a suggestion! Best regards,
It's a relay system. If it's tracking those flickers or bounces, then both counters should log them, right? I've utilized two separate counters to measure x0 pulses: one is a general-purpose counter, while the other is specifically designed to track x0 pulses exclusively.
High-speed counter inputs deliver faster response times, which can result in observable contact bounce. In contrast, standard inputs incorporate filtering methods that mitigate the appearance of contact bounces.
To analyze the performance of your +1 AlanHook output relay, connect it to an oscilloscope. This setup will allow you to observe the phenomenon of relay contact bounce. For visual references, check out these images demonstrating contact switch bounce: [Contact Switch Bounce Images](https://www.bing.com/images/search?q=Contact+Switch+Bounce&FORM=IDINTS). Best regards!
Thank you very much! All I require is a transistor model to run this program on. There shouldn’t be any issues with transistor models, right?
