PROFIBUS Errors

BF
Not lit 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.
Lit The PROFIBUS configuration is not correct. There is
NO communication with master.
Probable cause
Note Backup/Restore Operation failed: TS LED Indicator will be Lit for 2 seconds.
Probable cause
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.
Probable cause
Correction
Backup the data again.
Reinstall the Unit in which the data was being
restored and turn the power ON again.
• 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?
---
Correction
Refer to section 4-2-1 Power Supply Errors.
Check whether the connector is inserted prop-
erly.
Wait until the restore operation is completed.
Wait until the backup operation is completed.
Turn the power OFF and then ON again.
Replace the Unit if the error recurs.
---
Correction
• 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.
• 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.
