Hi, I would like to seek some professional help from you guys. First of all, im using TIA Portal V13 SP2 and im using a counter module, 6es7-138-6aa00-0ba0 and i have this encoder with 1024 pulse per revolution. This encoder will be attach to a wheel to measure wire length, and Speed (m/min). -For my counter module parameters (counting behavior) i change the high counting limit and low counting limit to 1024 and -1024 respectively and set "to start value" when counting limit is violated. i do this because i want to measure also the number of rotations. Is it right to adjust the high and low limit value to get number of rotation? Or is there any other way to calculate for this? -to calculate the RPM, kindly confirm that the formula is (frequency*60)/1024. i have seen this formula while browsing the forum. My counter module measured value is set to frequency. is this the frequency that i need to multiply with 60 and divide by 1024? -for speed(m/min) calculation, formula i use is wheel diameter(user input)*RPM*Pi. -to calculate the wire length. client require to have this "K-Factor" which is in m/rev. this "K-Factor" is user input. As for my understanding i only need to multiply this K-Factor (m/rev) to my number of rotation (rev) to get the length. Kindly advise me if there is a mistake that i need to change. Kindly download my logic in my dropbox link below since i can't attach file larger than 3MB. --Deleted Link-- Thank you very much AttachmentCounter.zip (193 Downloads) |
