4.7 Profibus Node Address Selection
To interface the C-BOX 300 with a Profibus network, the Node Address should be set
using the rotary switches placed in the cover inside.
The valid address range is from 000 to 126.
If an invalid value is detected (127-199) the C-BOX cannot communicate with the
Profibus network and the green LED remains off.
The Node Address can also be assigned through VisoSetup. Refer to Help on-Line.

It is recommended to use only commercially available PROFIBUS connectors for
connecting to the bus. If the C-BOX is installed at the beginning or end of the
PROFIBUS cable segment, it is recommended to use PROFIBUS connectors, which
contain an integrated terminating resistor.
To ensure that the C-BOX operates without errors, the shield of the PROFIBUS cable
must be grounded.
• Ensure that the PROFIBUS connector uses the correct pin assignments.
• Attach the PROFIBUS connector to the PROFIBUS interface socket on the C-
BOX 300 and secure the connector with the retaining screws.
