hdnosseini, I certainly agree that S7 memory structure makes it difficult to perform this kind of indirect addressing. But I also think that S7-SCL compiler lacks one serious point - possibility to concatenate (or even create or interpret) pure plain text instructions (one interesting discussionhere). If one was able to concatenate instructions within a loop, something like: DB40.DBX[i]:="MOTOR_(i)" with quotation marks meaning that enumerator "i" besides motor does not refer to address, but to instruction index, many things in SCL would be easier to acheive. Best regards. |
