5. Address list
ASCII mode:
 Reads one or more parameter values: 3Ah (start bit'：') + 30h 31h (station address 01) + 30h 33h
(function code 03h) + 30h 30h xxh xxh–32h 36h xxh xxh (Modbus address 00xxh–26xxh) + xxh xxh
xxh xxh (reading length 1) + LRC (checksum) + CR/LF
 Writes one parameter value: 3Ah (start bit'：') + 30h 31h (station address 01) + 30h 36h (function
code 06h) + 30h 30h xxh xxh–32h 36h xxh xxh (Modbus address 00xxh–26xxh) + xxh xxh xxh xxh
(writing value) + LRC (checksum) + CR/LF
 Writes 20 parameter values: 3Ah (start bit'：') + 30h 31h (station address 01) + 31h 30h (function
code 10h) + 30h 30h xxh xxh–32h 36h xxh xxh (Modbus address 00xxh–26xxh) + 30h 30h 31h 34h
(word data length) + 32h 38h (byte data length) + xxh xxh xxh xxh (the first writing value) + ... + xxh
xxh xxh xxh (the 20th writing value) + LRC (checksum) + CR/LF
RTU mode:
 Reads one or more parameter values: 01h (station address 01) + 03h (function code 03h) + 00xxh–
26xxh (Modbus address) + xxxxh (reading length) + CRC (checksum)
 Writes one parameter value: 01h (station address 01) + 06h (function code 06h) + 00xxh–26xxh
(Modbus address) + xxxxh (writing value) + CRC (checksum)
 Writes 20 parameter values: 01h (station address 01) + 10h (function code 10h) + 00xxh–26xxh
(Modbus address) + 0014h (data length, count by word) + 28h (data length, count by byte) + xxxxh (the
first writing value) + ... + xxxxh (the 20th writing value) + CRC (checksum)
