Thank you 🥳
thank you sir giving us free your expertise and support
thx
If your component has a range of 0-100 you have a total range of 100. This means that each 4ma equals 25 (100/4) and you now know the size of your supplying 4ma. You then put in -25 as min on the norm_x you have achieved the same end result in one network as you have after making the conversion function. Keep it simple.
For analog integer values for each and every sensor is from 0-27648. Hench 0=0 and 100=27648.
For 20 mA is equal to 27648
1 ma is equal to 27648/20
so, 4 mA is equal to 1382.4*4=5529.6.
Why there is 6912 in subtraction block ? convert 4-20 to 0-20 thanks for the answer
How could I convert analog sensor voltage (0-10V) to 4-20mA. And what are the PLC settings?
500 om resistans
What is 27648??
Why u r choosing the two value (5229.4& 6912.0)there is any formula to choose that value pls help me dude
0-20 have 20 value as 27648. then 1value is 27548/20 =1382.4.
4-20 is lost 4 value as 4 * 1382.4 = 5292.6
@@HungVu-dj5ti 27548/20 is 1377.4. But thanks for info too!
sound ?????
Without sound :)
@@JohnGvideo why make such videos without explaining
