Fieldbus interface 55
5.3.2 Troubleshooting
Check the following settings if the slave does not respond:
̈ Did you start the slave and switch on the master?
̈ Are all cable connections ok (electrically and mechanically)?
̈ Did you set the correct address at the slave? Check the DIP switch
and HEX switch settings. The settings are described in the product
manual. Products without DIP switches have the following default
settings: CAN address 127 (7F
h
) and baud rate 125 [kBit/s]. You
can change these settings via CAN itself or by means of the PC
commissioning tool via the RS 485 interface.
̈ Did you set the same baud rate and the same interface parameters
for the master and the slave?
If the slave still does not respond:
̈ Open the cover of the connector housing.
̈ When a slave works properly with the power stage disabled, the
LED in the connector housing flashes constantly at 0.5 Hz (1 sec-
ond on, 1 second off). If this is not the case, the product is inopera-
tive. See the product manual for information on errors and
troubleshooting.
̈ Compare the behavior of LED with the information in the table
below.
See the product manual for additional information on the cause of errors
