Hi, I have a sensor that gives me a signal 0-10V, according to the pressure (0-1 meter) and I do a Norm_X function and after I do an Scale_X function. Thanks |

Not sure if this will work with a real analog signal but might be worth a try. Check out the small user program in Step7 attached where MW130 is the level input, instead of subracting from the level you can add 5 every time when you start at zero level and compare the difference. Then you can use M50.1 to trigger your fluid injection.AttachmentLEVEL_2.pdf (406 Downloads) |

Hi Bruno, check out the revised program in TIA portal which is attached as pdf. Change the compare block to a greater than block and use the move function to reset the count to 0 when the level drops below 5. I am not sure however if the pressure sensor for the level is the correct solution for such a small tank, you might need to look at other level sensors to give a more accurate and updated response to the fast changes in the level.
