7.5. Parameterization and configuration
7.5.1.
Parameterization
By parameterization the control provides the slave with information required for process data exchange. The
information comprises PROFIBUS –specific data (octet 1 to 6) and user-specific information as for example
the required measuring resolution. User-specific information can be altered any time during the projecting
phase using an input window.
The slave verifies the data transmitted by master with its own stored data upon admissibility. The slave will
not inform the master of the result until a diagnosis request after configuration.
7.5.2.
Configuration
Configuration defines the scope of cyclic process data communication in both directions. The slave compares
the target configuration with its own stored one and informs the master about the result in a subsequent
diagnosis request.
From the master's point of view, encoder position values are input data and data transmitted to the encoder
are output data.
The present clock-synchronous encoder applies telegram 81 of the PROFIdrive profile. This telegram
comprises two words output data and 6 words input data.
7.6. Diagnostic signals
Clock-synchronous encoders utilize alarms in line with PROFIBUS DP-V1 replacing device-specific
diagnostic signals as per DP-V0. There is no distinction between alarms and warnings.
Diagnostic data comprise the standard diagnosis (bytes 1 to 6) and, in case several alarms must be
transmitted, both the length of the diagnosis extension and the channel-specific diagnosis (3 bytes each) of
each alarm to enable a clear alarm specification.
