Hello, Not mutch happening in that FB, just a few move's from the inputs of the FB to the outputs off the FB, some calculations for speed torque, etc and some conversions to get the bits at the right format and place. I think (let us know if i'm wrong) you want to know how to use this block) Well, start with deleting the DB 22, then open OB1 in ladder or FBD. Call FB22 and let Step-7 generate a new DB22. Now you can see the Block with inputs and outputs (with comment) You have to get a GSD file to import in your hardware config, to let this FB work. Attached the program, with the changes. If you need to know more, let us know. Regards, Marcjan AttachmentVacon__1.zip (456 Downloads) |

O.k., now whe know why you want the explanation off that block. I have at the moment no acces to my S7 tools, can have a look at it next day. But there are others here, real cracks so don't worry. Have attached a explanation off all the STL commands, hope that helps you a bit. Regards, Marcjan AttachmentSTL-cheat-sheet-by-category.pdf (481 Downloads) |

New question published by AutoGen_7146170 is split to a separate thread with the subject Trying to implement this block on step 7, 5.6 , vacon20 and the opte5 card. Best regards |
