西門子PLC300。上位（vb)從PLC讀上來的數據是倒的？或者說，PLC存儲器高低位和別人的是反著的？見下。謝謝

這是上位要往PLC寫數據之前的操作，需要把數據倒過來一下。

CopyMemory pReadBuffer1(0), a, 4

pReadBuffer(0) = pReadBuffer1(3)
pReadBuffer(1) = pReadBuffer1(2)
pReadBuffer(2) = pReadBuffer1(1)
pReadBuffer(3) = pReadBuffer1(0)

MyHex = field_write_ex6(100, 2, 20, 12, 12, pReadBuffer(0))

求介紹西門子存儲器 是倒著的 詳細學習資料（網址也可喲）謝謝！
