Hi J_Bell,

Without a "Partner_ID" communication does not happen.

The "Partner_ID" should be "0001 A050" or "0002 A050". But it is blank.

When I compile, I get anErrormessage:

Error: SIMATIC 300(1)\CPU 315-2 DP : 0001 A050: Cross-project connection has not yet been merged (Edit menu - 'Merge Connections...').

I get the same on the other project.

I go to the "Edit" menu and select "Merge Connections". Even though both Netpro connections are open at the same, I cannot merge the connections and compile Netpro (both projects), without error.

I made sure I had the one connection as Active and the other as Passive.

The only way I got it to work, was to create a Multiproject, and theninserted both projects into the Multiproject. I then opened both NetPro connections, and then I again selected "Merge Connections", and now I had a merged connection, and I could compile NetPro, for both projects, without error.

Surely there should be an easier way.



Regards.

Hi,

How can you test this connection if you are only simulating the PLC's. I need to prove that the communiction is functionl.

Thanks

Gunnar

hi Gunnar

What are you talking about?

In this Tread was the last post in 2009!

Since then many happend in the S7-world.

I think, the best is to describe your problem in a seperate, own thread.

Hi,

Well,

The way to do it now is the same as it was in the past. This has not changed despite the advancement in the versions of S7 / PCS7.
The connection to the partner must be unspecified and does not require merge of subnets.

To use S7 connections see: https://support.industry.siemens.com/cs/ww/en/view/17628518
