All mentioned byte indices are 0-based!

The first 16 bytes are a ASCII encoded String Hello, S7! with trailing spaces.
byte 16/17 are the max/min value of a signed byte (127/-128)
bytes 32-33/34-35 are the max/min value of a signed short
bytes 48-51/52-55 are the max/min value of a signed integer
bytes 64-71/72-79 are the max/min value of a signed long
bytes 80-83/84-87 are the max/min value of a float
bytes 96-103/104-111 are the max/min value of a double
bytes 1024-2048 are just bytes starting from 0 continousely incremented
 

仿真PLC:  DB1的   地址段 2048 Byte

2048个byte: DBB0 -- DBB2047 ( 后面的数字是十进制表示）

1 读写 前两个byte： DBW0  (word 16位, 两个byte)
                                         DBB0 - DBB1的两个byte
2 读写 前两个byte：DBW2  - 2是起始地址 DBB2
                      DBB2 - DBB3
3 读写 前两个byte：DBW4  - 4是起始地址 DBB4
                      DBB4 - DBB5
4 读写 4个byte   ：DBD6  - 6是起始地址 DBB6
                      DBB6 - DBB9

B: Byte
W: word (wbyte)
X: DBX8.1(第8个byte的第一位）
Sting: DB1.DBX20
