A.1 Communication
● PROFIBUS interface
The PROFIBUS interface is described on the CD of the converter in the document
"Supplementary component descriptions".
● PROFIBUS diagnostic LED
Note
A teleservice adapter can be connected to the PROFIBUS interface (X126) for remote
diagnostics purposes.
PROFIBUS address switch
On the CU320-2 DP, the PROFIBUS address is set as a hexadecimal value via two rotary
coding switches. Values between 0
upper rotary coding switch (H) is used to set the hexadecimal value for 16
coding switch (L) is used to set the hexadecimal value for 16
Table A-6
Rotary coding switches
Setting the PROFIBUS address
The factory setting for the rotary coding switches is 0
There are two ways to set the PROFIBUS address:
1. Using a parameter
– To set the bus address for a PROFIBUS node using STARTER, first set the rotary code
– Use the parameter to set the address to a value between 1 and 126.
For further information, please refer to the converter List Manual.
2. Using the PROFIBUS address switches on the Control Unit
– The address is set manually to values between 1 and 126 using the rotary coding
