found an instruction PRV, will try to do some tests tomorrow, because it is hard to test in simulation mode. will keep you posted

Thanks, looks like my math portion is working now. first converted all of the variables to floating and than did the calculation. But how do I read the frequency on the CIO001 to make my application work? Looks like there is no function for reading pulses per minute (ppm) test_pulsteller_v1_6.cxp

Thanks Pdl for your reply, I did like you said and downloaded the manual started reading and trying, indeed had some problems setting up the communication with the NQ but that’s all working now. But, I still can't get my program to work the problem is (I think) that the outcome of the last divider is a number like 0,00006754 I have to multiply this with the ppm on CIO3 but can't find a function for that. I attached the file, maybe you will have a look? test_pulsteller_v1_5.cxp

Hi, i'm using the CP1L cpu with NQ3 Hmi

Hello all, I am a newbie to this plc thing and already have a great challenge I need to calculate following; D0=((D1*D2)*(D3/1000000))/1000 = 0,0002170 kg/pulse D1 = Number of strands = 2 D2 = Diameter of roll = 45.2 mm D3 = thickness of strands= 1200 D4 = totalized count of IN1*D0 D5 = ppm IN1*D0 = xx.xx kg/min Every time a input signal is presented at IN1 it have to be multiplied with D0 to see the KG/min In1 has a frequency between 0 and 6000 ppm The problem I have is getting D2 into the formula because of the decimal point and calculating the ppm on In1 to display the actual rate of D5 Anny suggestions are welcome
