Hello. What size of data do you want to transfer to S7-CPU? Look at themanual, chapter 4.3.1, where you will find the overview of 3-type data transfer, and use the third (data sets/blocks). |

Hello. You may use "Communications utility, trace" (function block TRCC) or "Pointer-based communications" (function block DB_P). You read about this in the manualSIMATIC D7-SYS Selecting Function blocks(chapters 1.4.4 and 1.4.8). |
