For a master/master connection, use the client/server method.

One LOGO! is the client, the other LOGO! the server. The client LOGO! requests data from the server LOGO!, the server LOGO! sends data according to request from the client LOGO!. Which of the two LOGO!s is the client is no matter and can be arbitrarily set by the user. In my example it is the LOGO! with the low IP address the client, it becomes the state of the inputs I1 and I2 to the server LOGO! And the client LOGO! Asks the state of the two inputs I1 and I2 of the server LOGO! from. The two inputs of the respective LOGO! switch in the other LOGO! the outputs.

Setting up the client LOGO!:
Create that program similar to the attachment. Configure the IP address of the client LOGO! and set up a client connection. See video “Client connection.wmv”.

Setting up the server LOGO!:
Create that program similar to the attachment. Configure the IP address of the server LOGO! and set up a server connection. See video “Server connection.wmv”.

Simulation:
See video “Simulation.wmv”.

Since all videos are too large for an attachment, I distribute the videos to several Posts.

Here's the video "Simulation.wmv".

That's the problem with LOGO! 0BA7. It can only send network outputs (digital or analog) to a slave LOGO!.
In this case, you must use "Parameter-VM-Mapping"
