Status byte (byte x+4)
The structure of the status byte corresponds to the PROFIBUS PA profile. With the ET 200iSP, the
following status codes of the PROFIBUS PA profile are used:

Byte x+4
Status codes used by the PROFIBUS PA profile for ET 200iSP:
• 01001100 (4C
• 00011000 (18
• 00001100 (0C
• 01000111 (47
• 10000100 (84
• 10000000 (80

HART data records

Requirements
You need this information if you go beyond the standard applications of STEP 7 and SIMATIC PDM
applications or use your own configuration 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 Profile HART Version 1.0. For more information on the HART protocol,
refer to the PROFIBUS DP HART Profile Application Guidelines.

0 Description
HART status byte for HART measured value 1, as specified for
HART
Bit 0 and Bit 1: Limits: Reports limit violations
Bit 2 to bit 5: Sub-status: differentiates and refines the qual‐
ity of the associated measured value. Meaning depends on
"Quality". See operating instructions of the HART field device
Bit 6 and Bit 7: Quality: Describes the basic quality of the
measured value
