Hello , There are rules for creating logics in LAD and it is compulsory to follow them.In STEP7,LAD editor will not allow you to create wrong logics in Nature in most of the time. For your case in TIA Portal,error is clearly pointed out. "The Network contains more than one current path".There are rules that should be followed for error-free operation. Here compiler is helping and pointing out that error.For complex LAD logics, try using branches. See the following topics: Rules for the use of LAD elements (STEP7 Professional V11) Rules for the use of LAD elements (STEP 7 Basic) Best regards Hamid Hosseini |

is it wrong?? Hello, Writing on inputs (e.g %I0.0) are possible as they are parts of process image (section in system memory) as shown in attachment.I think that is not cause of mentioned error. Please read the following section from online manual of STEP7 in the attachmnet (PII). Best regards Hamid Hosseini AttachmentPII.zip (322 Downloads) |
