Response message from a digital MFC controller to Master Controller

MAC ID (0

– Master controller))

STX(0x02)

Command Code(0x80 for read)

Packet Length(0x05)

Class ID(0x31)

Instance ID(0x03)

Attribute ID(0x06)

Data Byte #1(LSB)

Data Byte #2(MSB)

Pad(0x00)

Checksum

Actual Temperature Reading (psia)

Output Value (hex)

Output Value (decimal)

0000

500

6000

24576

The actual temperature reading is calculated from the output value:

Actual Temperature Reading (

⁰

K) = (Output_Value/Full_scale_output_value)*500

Where Full_scale_output_value = 24576 (0x6000)

Actual Temperature Reading (

C) = ((Output_value/Full_scale_output_value)*500) - 273.15
