Many thanks for your time Duris_I, and you've all reason my old Italian panel is a marchesini FIM30 and has RS-232 serial interface. Now the new recommedation that I followed is Combined configuration with WinCC (TIA Portal) and STEP 7 V5.x because my PLC is a old version and is not compatible with TIA PORTAL V13 and my panel it is. When I did the procedure I could not see the symbols for my HMI variable, but I could see ONLY the DB in TIA PORTAL, then I receive a new recommendation and this was that in Step 7 V5.5 I needed create my symbol table, in this moment this table just had 2 symbols WR_REC with SFC 58 address and RD_REC with SFC 59 address. Then I created my symbol table with all necesary variables and now I can see the symbols in TIA PORTAL for my HMI variables. But the new questions are: 1. When I created my symbols table in step 7 v5.5 the size of this table increse considerably ¿Can this size affect my PLC memory? (see picture 1) 2. In other project in the same plant has the same application running over the same CPU and the same panel KTP 700. On symbols table in step 7 V5.5 only use 3 symbols WR_REC with SFC 58 address, RD_REC with SFC 59 address and READ_CLK with SFC 1 address. ¿How was the integration between PLC and panel possible with only this symbols? This is my major question. ¿Why they dont need this kind of extensive symbols table? (See picture 2). Thanks a lot, really I'm so new in Siemens programming, I was a Rockwell user..

Hello Murof, Thanks for your help, check the attached document. ¿Is the correct way to create my symbols table in Step 7 v5.5 to view it in TIA PORTAL? ¿Can you share me some info to use my DB to view is variables in TIA PORTAL?
