Hello Ray;
If you do not have the original PLC code in your programming PC, there will be no comments or symbols in the uploaded program. This makes your troubleshooting more difficult, unfortunately, you will have to rely on alternate sources, such as electrical drawings, to locate the inputs and outputs of your data. For confirmation, look at this screenshot, extracted from the Programming with Step 7 v5.5 maNual: https://support.industry.siemens.com/cs/ar/en/view/45531107 Hope this helps, Daniel Chartier |
