 36 Structure of the coding byte
The content of the coding byte depends on the configured failsafe mode in the particular
function block. Depending on which failsafe mode has been configured, status information
in accordance with PROFIBUS PA Profile Specification 3.02 is transmitted to the PROFIBUS
Master (Class 1) via the coding byte .
Determining the measured value status and device status via the diagnostic behavior
When the diagnostic behavior is assigned, this also changes the measured value status and
device status for the diagnostic information. The measured value status and device status
depend on the choice of diagnostic behavior and on the group in which the diagnostic
information is located.
The diagnostic information is grouped as follows:
• Diagnostic information pertaining to the sensor: diagnostic number 000 to 199
→  170
• Diagnostic information pertaining to the electronics: diagnostic number 200 to 399
→  171
• Diagnostic information pertaining to the configuration: diagnostic number 400 to 599
→  171
• Diagnostic information pertaining to the process: diagnostic number 800 to 999
→  171
Depending on the group in which the diagnostic information is located, the following
measured value status and device status are firmly assigned to the particular diagnostic
behavior:
