2…239 Response data according to HART specica‐
tion
Only present when "Response result" = 4 =
"Successful, with data"
"Response control" coding:
Bits 0-2: Response result (processing status)
0 = Inactive
1 = Inactive (reserved)
2 = Waiting
3 = Waiting, executing
4 = Successful, with data
5 = Successful, without data
6 = Error, with data
7 = Error, without data
Bit 3: 0 = Burst mode not active
Bit 4: 0 = Response data come directly from the HART device
Bit 5: 0 = Response data in transparent message format
Bit 6: 0 = SHC mode is not active
1 = SHC mode active
Bit 7: 0 = HART response
"HART group fault display" coding
