Hello everyone. I am new to using high speed counters and logix5000. I am using a 1769-L27ERM-QBFC1B controller with an embedded high speed counter. Currently the system is working but I am getting a large overshoot on my counter. My flow meter is providing a good signal to the PLC but I want to know if there is a different way to control my output. Currently I am using the counter input in my main sequence of logic and also use output off/on masks. I believe that I am getting overshoot from my scan time. Is there a way that I can once the HSC reaches its set point that it will automatically turn off an output without waiting for the PLC to scan the logic? The older SLC programs are using a #M10 word to control the output without waiting for the PLC to scan and eliminating the large amount of overshoot that I am seeing.
