The PROFIBUS interface of the level transmitter supports the PROFIBUS-PA Profile Version
3.02. In this Profile the Condensed Status and Diagnosis has replaced by default the Classic
Status and Diagnosis of the PROFIBUS-PA Profile Version 3.0. The Condensed Status and
Diagnosis has been created to make diagnostic events more obvious and to allow predictive and
preventive maintenance. Nevertheless Classic Status and Diagnosis is still available for the level
transmitter. It is implemented for backwards compatibility to "older" devices or PLC systems
which do not support Condensed Status and Diagnosis.
The device may be switched between "Condensed Status and Diagnosis" and "Classic Status and
Diagnosis"
• automatically during start-up of the cyclic data transfer by setting the parameter PRM_COND
within the Set_Prm service data.
• using an engineering tool (e.g. DD/DTM) to write the parameter COND_STATUS_DIAG (slot 0,
index 43).
Coding for both parameters is:
• 0: Classic Status
• 1: Condensed Status (factory setting)
The coding of the status value depends on the active status and diagnosis mode. It is described in
the following tables.
Condensed Status Condensed Status Condensed Status Condensed Status
The Condensed Status codes have been defined to allow easier decoding of the information
provided by the PROFIBUS devices. The coding is shown in the following table:
INFORMATION!
The parameter COND_STATUS_DIAG cannot be modified directly if cyclic data transfer is active.
Nevertheless it is reset to the factory setting if a reset to default data is requested by an
engineering tool.
