Hello , As shown in the attachmnet you have written in the same address 13 times (check it by "go to location" capability in LAD/STL/FBD editor).In some cases they are constant and some of them are variables. I suggest to check all cases to see in which case the address written by zero! Also check this: indirect adress tracineHope this helps Best regards, Hamid Hosseini AttachmentDB197.zip (32 Downloads) |
