Most likely because the conditional Jump (JC M001) is active and the logic in the bottom is NOT executed(I can't be 100% sure though as your screendump does not show the RLO neither the STAcolumn). I hope this helps |

Hello mexflexx ok, let's call it "a picture of what you saw on your computer screen and which you attached to your post as plcsim.jpg". For ease of typing I will refer to thisfomnow on as a "screendump".
Can you please scroll a little bit to the left and make the RLO and STA columns visible?
I'm afraid I don'tunderstand what you are trying to say. The RLOcolumn will show you the Result of the Logic Operationwhich determines (in your case) if the JC (conditional Jump) is executed or not. The STA column lists the STAtus of thebit that is being "questioned" so I'm not too sure how these columns can be the sameas "the other ones"
Again, not too sure what you mean. Assuming the JC comand is active, the logic will jump over the bottom part and continue at the jump label, hence there is no use in trying to display any status values in the bottom part of your logic (there is no status because the logic is NOT executed). I hope this helps and bear in mind too that you can click on any of the STL commands and use F1 to get context sensitive HELP onthem. |
