Hello Rashid; The complete address of your bit should include a DB number designation, as it is part of that DB. For example, DB100.DBX13.6 is a valid and complete address. Step 7 allows you to "open" the specific DB (DB100 in this example) in preceding rungs to the one you have captured. Once the DB is opened, you can use the different bit and word addresses inside the DB in your logic. You will find all needed explanations for the Open DB instruction in the LAD manual for S7-300 CPUs: https://support.industry.siemens.com/cs/ww/en/view/45523822 Can you find the Open DB command in the rungs preceding the one you showed us? Hope this helps, Daniel Chartier |
