The starting address of Modbus register: The starting address of register or switching value or loop and so on
in Modbus slave and the range is 0~65535.
Data number: The length of data. Two bytes are one data length.
The starting address of memory mapping (hexadecimal): The starting address of data in memory buffer of the
module.
The address range of data mapping in the module memory:
Read command: 0x0000~ 0x01FF
Write command: 0x4000 ~ 0x41FF
When write command is used exchanging locally, it also can use: 0x0000 ~ 0x01FF
Bit offset of memory mapping (0 ~ 7): For the bit operation commands, the position range of start-bit byte is
0 ~ 7.
Bytes swap: There are three kinds of type, No swapping, two bytes swapping, four bytes swapping. The byte
display order of Modbus and Profibus-DP is MSB being preferential; the byte display order of DeviceNet is LSB
