Figure 6-2 Receive HART Command 3 data
(5) Parse the Modbus response data.
Response Data => 01 04 1A 00 00 A1 41 22 01 3E 0C C5 C5 20 B0 B6 41 C0 78 42 39
91 C9 00 C5 00 00 00 00 E5 B0
Register data =>
00 00 A1 41 22 01 3E 0C C5 C5 20 B0 B6 41 C0 78 42 39 91 C9 00 C5 00 00 00 00
Because the unit of HART-710’s database is byte and the unit of Modbus register is
word and the Modbus register is composed of database’s byte and the order is low byte
first.
(For example: Modbus register0 = 0x3412, database byte0 = 0x12, byte1 = 0x34).
So we need to change the byte order. So the data will be as below.
00 00 41 A1 01 22 0C 3E C5 C5 B0 20 41 B6 78 C0 39 42 C9 91 C5 00 00 00 00 00
