Error Codes
The error codes are described in the following table. The detailed error code
will provide detailed information on an error.
Note
1.
The time information from the CPU Unit is used in the PROFIBUS-DP
Master Unit.
2.
An error record is not created in non-volatile memory when the error con-
cerns an Error Log Write error.

are on the same network.
• Verify that the Highest Station
Address setting includes any
other Master Address on the
bus.
