Hello,

I have two 

1. One PLC with DP/DP Coupler who is connected to Common PLC (profibuss adress:2, node 10)
2. Other PLC with DP/DP Coupler who is connected to Common PLC (profibuss adress:2, node 10)
*Same just duplicated. One for one furnace one for other.
3. Common PLC with 1. and 2. PLC on  hardware configuration with node 32 and 64.
(Configuration in attachment)


- I always get Bus fault and system fault.
- When i try to see my PLC online on hardware i can't.


If anybody knows how to solve this problem?

Best regards.

 Hello Deco,

 sorry but what you want to do? Communicate between three PLC via two DP/DP coupler?

Hello Deco;

Please take a few minutes to read the following document, explaining the basic principles of configuring and using a DP/DP coupler:

DP/DP Coupler

A DP/DP coupler is a special Profibus slave with 2 connected slave units; each side of the cpoupler is connected as a aslkave to a DP-master, and the data from one slave is transfered to the other, therfore permitting exchanges between the 2 DP masters as a gateway.

See the attachment below.

What are you planning to do with the COMMON PLC in your diagram? 

Hope this helps,

Daniel Chartier
