6.2. Configuration
Configuration means definition of type, length (amount) and direction of the process data as well as the
way they are further processed. The type stipulates the data type and whether the data are contiguous
(consistent). The length (amount) determines the number of data bytes available. The data direction
defines whether data are transferred from master to slave or vice versa. The length comprises optionally
one or two words, both of consistent data. The configuration is compared to the configuration stored in the
slave. The slave informs the master of the result in the following diagnosis request. Angular values by the
inclination sensor are input data from the master’s point of view, values as preset or offset are output data.
Admissible configurations
Configuration Significance
0xF1,0xD1,0xA0
2 words input data of data consistency for angular values of the inclination
sensor,
1 word output data for parameterization of resolution/offset/preset in Data
Exchange Mode
Diagnostic messages
Diagnostic messages contain information on the respective status of the inclination sensor. Diagnostic
messages comprise Profibus-relevant information as well as device-specific information. Utilizing this
information the master either controls slave communication or passes the information over to the higher-
level system.
The master requests diagnostic data prior to both parameterization and configuration. Thus it is ensured
that the slave exists in the bus and the data saved in the control’s software are congruent to the data
stored in the slave. Furthermore the slave is able to transmit a diagnostic incident in Data_Exchange
Mode. The master will then request the diagnostic data.
The status indicators (DUO LED red/green) integrated in the bus cover visualize part of this information.
