PROFIBUS Errors
If power supply to the Unit is correct and the Communication Unit and the
SmartSlice I/O Units are operating correctly, problems in the PROFIBUS Con-
nection can be determined using the BF LED indicator (Bus Fail) on the
PROFIBUS Communication Unit. The tables below lists the BF LED options.

Red
Backup operation failed (See Note).
Backup the data again.
Restore operation failed (See Note).
Reinstall the Unit in which the data was being
restored and turn the power ON again.
SmartSlice I/O Unit configuration error occurred. Check the following items.
• Are more than 64 I/O Units connected?
• Are more than 128 bytes of I/O data being
used?
• Has the I/O configuration changed since the I/O
configuration table was registered?
Green
The Slice bus is operating normally.

No PROFIBUS Communication error encountered. The Unit is exchanging I/O data with the Master Unit.
Flashing
The PROFIBUS configuration is not correct. There is
however communication with Master Unit.
• Check the configuration and the parameter data of
the slave (See Note 1).
• Verify that the first selected I/O module is the “COM
status” Module (see Note 2).
• Verify that the selected configuration matches the
physical slice configuration attached to the PROFI-
BUS Communication Unit.
• Verify the Profibus allocation of the SmartSlice I/O
Unit is according the description. Check the Profi-
bus Diagnostics. Please refer to
Appendix B Slave
Diagnostics Message
.
Lit
The PROFIBUS configuration is not correct. There is
NO communication with master.
• Verify that the Unit has the same station address as
in the master's configuration.
• Verify that no station address is used twice.
• Verify that the Master Unit is ON-LINE.
