QUOTE: /////////////////////////////////////////////////////////////////////////// But here I couldn't find wrong operand or address. And the point was only left for DB exists or not. So that I cleared that point. But problem was totally different. It was language problem.
/////////////////////////////////////////////////////////////////////////// "U I0.0" is a wrong operand if we are working in English/English selection. "A DB1.DBB0" is also a wrong combination of operand and address. I still think that it a wrong opeand issue.In case of non-existing DB, you can download the project to PLC but with an error (even you download error OBs). QUOTE: /////////////////////////////////////////////////////////////////////////// Thank you for this information. But even if : U DB5.DBX 0.0 = "Destination".DB6_VAR1 is executed without error when I run CPU DB6.DBX 0.0 maintain the same value !!! /////////////////////////////////////////////////////////////////////////// Dear Dadoui, I also suggest the starters' Guide for STEP 7 here.This will help you to learn STEP 7 in a more strong way: HD_STEP7 Starting Point Check the following manual: 1-Working with STEP 7 V5.4 Getting Started 2-SIMATIC Programming with STEP 7 V5.5 and these demos: 3-The SIMATIC Manager 4-The Basic Languages LAD, FBD, STL 5-The SIMATIC S7 Architecture and these 2 books:
