There are about ~20 bytes of data at 3 different input starting address for a total of ~60 bytes into 3 different arrays. All this will be done in TIA Portal V11 SP2 Upd3 using an S7-1200 PLC, preferably in SCL. I think this is fairly easy to accomplish but cannot get the portal to cooperate and tell me exactly how to parameterize based on indirectly addressing IW[#]. Suggestions welcome. In more detail: Copy IW[68..87] to myDB.myArray1[0..9] (of word) Copy IW[88..107] to myDB.myArray2[0..9] (of word) Copy IW[108..127] to myDB.myArray3[0..9] (of word) If the sizes do not match, that's ok as I am using an example rather than exactly like my program needs.

For now, I manually typed all the move commands referencing all the input words one word per move command, and manually indexing the destination array. I know in legacy Step 7 this is fairly easy to do. The portal still has a ways to go even after the recently released V11 SP2 Update 4.
