Hello Everyone :

how can I interconnect between two cfc diagram who are in a different station ( different CPU ).   

Hi,

It is possible to using AS wide connections. Both stations are required to be in the same project. Then just connect io of one block to other like normal Cfc only. The only thing to take care is that blocks must not be processed faster then 200ms. Call them in slower cyclic OBs.

Hope this helps.

Kbv.

thanks a lot .

They are in the same project but it still impossible to achieve this connection.

Clearly what I want is, to connect between tow FBs Blocs .

But these blocs belongs to different CFC diagram, each of theme is also in a different station, but all of theme are in the same project.

Please any suggestion am realy blocked.

It is impossible.

You can make interconnections between blocks in one CPU. The reason is quite simple - interconnections are assignments, not communication connections. You can see this if you open any FC that corresponds your OB

Thank You.

Did you follow the link of Kbv?

Did you especially ceck these prerequisites:

• The PLCs involved are located in a common project or multiproject.
• The network configuration has been performed with NetPro.

What PLC you have? What is the firmware of the PLC?

The PLCs involved are located in a common project , in Netpro I use TCP communication (PROFINET). 

Each CFC diagrams are in a different station but in the same project.
