The drive has encountered a conflict where a functionality requested by the PLC via Fieldbus Adapter A is either not available on the drive or has not been activated in its configuration. This prevents proper fieldbus control and data exchange, leading to communication errors or incorrect drive behavior.
Click steps to track your progress.
Verify the fieldbus communication profile (e.g., Profinet, EtherNet/IP) selected in the drive (e.g., P5-01) matches the PLC.
Compare the drive's GSDML/EDS file with the PLC configuration for any parameter index discrepancies.
Ensure the requested functionality or parameter from the PLC is activated in the drive's main configuration (e.g., via P2-01).
Check data types and read/write access rights for all fieldbus mapped parameters.
Update the drive's firmware to a version that supports the requested functionality.
Set the drive to a basic fieldbus profile (e.g., generic I/O) and test communication with minimal data points.
