Status byte (byte x+4)
The structure of the status byte corresponds to the PROFIBUS PA prole. With the ET 200iSP, the
following status codes of the PROFIBUS PA prole are used:
Table 14-37 Status byte
7 6 5 4 3 2 1 0 Description
Byte x+4 HART status byte for HART measured value 1, as specied for
HART
Bit 0 and Bit 1: Limits: Reports limit violations
Bit 2 to bit 5: Sub-status: dierentiates and renes the qual‐
ity of the associated measured value. Meaning depends on
"Quality". See operating instructions of the HART eld device
Bit 6 and Bit 7: Quality: Describes the basic quality of the
measured value
Status codes used by the PROFIBUS PA prole for ET 200iSP:
• 01001100 (4C
H
) uncertain, initial value (before rst contact)
• 00011000 (18
H
) bad, no communication (communication error)
• 00001100 (0C
H
) bad, device failure (device fault)
• 01000111 (47
H
) uncertain, last usable event, constant (device is busy)
• 10000100 (84
H
) good, update event (re-conguring)
• 10000000 (80
H
) good, ok (no error)

Requirements
You need this information if you go beyond the standard applications of STEP 7 and SIMATIC PDM
applications or use your own conguration tool for HART communication.
Data record interface
The analog modules with HART use data records as the input and output interface:
The mapping of the HART commands and HART responses into the PROFIBUS DP data records is
based on the PROFIBUS Prole HART Version 1.0. For more information on the HART protocol,
refer to the PROFIBUS DP HART Prole Application Guidelines.
