Hello, I have read this guideline pdf as well. I am still confusing those descriptions insde. "Based on the changed processor architecture, the new S7-1500 controller generation always accesses 4 byte (32 bit) in "Little-Endian” sequence." What does it mean? How is the processor architecture changed? S7-300 processor uses bigger endian while s7-1500 uses little endian? But I searched online, it says the S7300 uses processor from infineon which stands for little endian of byte order. And if the optimized block stores data in little endian, but why in the attached pic, it still indicates 0,1,2,3 from lower to upper, still big endian? ------------------------------------------------------------------------------------------ |
