Dear Automation Program, 1-2: You cannot find them because in the program is using like indirect addressing (PEW (German mnemonics) [AR1,P#0.0]). If you go to FC2 block, Network 59 you will see ADDRESS and only "256" without PEW, then if you go to FC 254 on the Network 10 you will see L #ADDRESS --> SLD 3 -->LAR1 and then prepare the address to read and in the Network 11 prepare to write in the Drive.3: Sorry but I not work with TIA (not yet), I would not say one thing for another, sorry FC 254: Network 10 L #ADDRESS //256 SLD 3 // Pointer format LAR1 // Load address register L PEW [AR1,P#0.0] T DBW 0 and so on Network 11 L DBD20 T PAD [AR1,P#0.0] How can you calculate an offset for an ANY pointer or change the ... |

Hello, I will try, L #ADDRESS = 256 SLD 3 = 256.0 (2048) // Pointer format LAR1 = 256.0 // Load address register L PEW [AR1,P#0.0] = 256.0 --> PEW 256 T DBW 0 --> Now is DB97.DBW0 Look to DB97 L PEW [AR1,P#2.0] = 258.0 --> PEW 258 T DBW 2 --> Now id DB97.DBW2 and so on Used Of pointers and Indrirect addressing - Siemens Industry Online ... |
