Thanks. So, now, I have a length that I can give in myself ( in cm), and an analog value that's converted to a speed in cm/min. Is there a way to make a constant calculation of the remaining length? So: the length that I gave in should be constantly reduce, dependent on the speed (analog value). Purpose is to unroll a coil with fiber at a certain speed (analog value) and to know when the coil will be empty. In best case, we can constantly see the remaining length on the coil. Thanks in advance ------------------------------------------------------------------------------------------ |

Here an example.

Thanks a lot! I'll try to understand that now :D |

Thanks for that! Now I made the program myself, but seems like there's still something wrong. When I enable the I1, to start the cyclus, it doesn't start from the given value (here 10000) but it starts reducing from 0. Any idea what I do wrong?

That is the problem by LOGO!. The LOGO! can only calculate with integer values. |

In attachment another suggestion. Instead the length not in cm but in mm. Counters works with double integers. So is the start value instead 10,000 cm then 100,000 mm. AttachmentConstant_calculation_of_the_remaining_length_8.3.zip (503 Downloads) |

Yes, while the factor is 10 (mm instead cm) ... |

Here a version with a alarm output if the rest is lesser then 10,000 mm (10 m).

A OR block? |

Ok yes, sometimes even forgot the most simple things . But the program will become kind of a spider web |

With the other example, this should be possible?

Okay, but the maximum length is around 200m, so this shouldn't cause a problem I guess |

Okay, but I guess both things aren't just an easy adaptation to the program I already have? |

I can't say that because I know what you think you're capable of. I know, how it works. |

No I just changed the value to give in, so I can give in in metres, multiply it by 100 for the calculations, but seems like the rest of the program isn't working well anymore AttachmentLeegloopdetectie_5.zip (567 Downloads) |

In the simulation it seems for me that it works correct. |

Dear, I'm still working on the version with the counters, but I'm stuck again. For the moment, I change the start value manually on the TDE (here: 120000 mm). But I should want to change that value with two buttons (digital inputs). If i push one button, that value should increase with 10000 (10 m) and if I push the other it should increase with 100000 (100 m). Is there a possibility to do that?

No, there's no way for this. Because the start value can only changed by the display or remote. |
