 32 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 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 the group in which the diagnostic

information is located. The measured value status and device status are firmly assigned to

the particular diagnostic behavior and cannot be changed individually.

The diagnostic information is grouped as follows:

• Diagnostic information pertaining to the sensor: diagnostic number 000 to 199

→  143

• Diagnostic information pertaining to the electronics: diagnostic number 200 to 399

→  144

• Diagnostic information pertaining to the configuration: diagnostic number 400 to 599

→  144

• Diagnostic information pertaining to the process: diagnostic number 800 to 999

→  144

Depending on the group in which diagnostic information is located, the following

measured value status and device status are firmly assigned to the particular diagnostic

behavior:
