10.3.4 Register address distribution Table 10-2 Detailed Definition of Register Address of MODBUS Protocol 262 Request Respond Domain name (0x) Domain name (normal) (0x) Domain name (abnormal) (0x) Function 10 Function 10 Function 90 Starting address Hi 03 Starting address Hi 03 Exception code 03 Starting address Lo 00 Starting address Lo 00 Number (Hi) of registers 00 Number (Hi) of registers 00 Number (Lo) ofregisters 02 Number (Lo) of registers 02 Number of bytes 04 Register value Hi (F03.00) 00 Register value Lo (F03.00) 01 Register value Hi (F03.01) 00 Register value Lo (F03.01) 03 Address Space Description Function code 0000H - 6F63H For the function code FXX.YY, the high order is hexadecimal of XX and the low order is hexadecimal of YY.
For example, the address ofF00.14 is 000EH (00D=00H, 14D=0EH). Function code (not saved after power-down) 8000H-EF63H When the parameters are set with the function code 0x06 or 0x10, the function that “the settings are valid immediately and not saved after power-down” can be realized in the form of “original address +8000H”. For example, the corresponding address ofF00.14 is 800EH (=000EH+8000H).
