group address over different networks

Dear all.
I am relatively new to cbus. I have started working with it.
We have a villa project in which there are 2 networks.
Now I am facing a problem in the villa. The lights in the second network is turned on automatically. When I searched I found that these lights are turned on when the lights in network one having different group address but same group number is turned on. That is, the group addresses in both networks are different but the group number is same.
I know this is a simple thing but I couldnt figure it out myself.
Please help me. There is one touchscreen and wiser.
Thank You

 

adding to the point above, there is only one application.

 

Are you able to elaborate what you mean by different group address but same number? The group number usually makes up the group address....

 

What I meant is that the group number is same in both networks.
But the name I gave to the group is different in both networks.
How can I control lights having same group number in different networks seperately??

 

What you refer to as the number of the group address is what devices on the networks actually use to communicate with each other. The name that you have given to the group address is purely a textual representation to make it easier to understand what is going on in the configuration software. The text names (called "tags") for the group numbers are not downloaded to the units; they are just for use in the different commissioning software programs.

If you have 2 networks joined together with a bridge and you have the bridge configured to pass All Applications between the networks then you should use the Copy Tags feature of Toolkit to ensure that both C-Bus networks have the same tags on both networks to avoid this kind of thing in the future.

If you don't require any communication between devices on the different networks then you can just turn off the feaure in the bridges that sends regular Lighting messages across the bridge.

 

thanks alot
but if I clear the option to send messages to adjacent networks will I be able to scan the other network from local network and do programming..also, will it effect wiser and touchscreen in the local network to send messages to adjacent network?? i.e, from the touchscreen in local network i cannot control lights in the adjacent network, rt?

Also We have done projects in which this 'send messages to local network' is selected and we dont have this problem. In different networks we have same groups with different tags, and these control different channels seperately.

Where could have this problem occured for me in this project?
Thank you again

 

Yes.

It depends on how you have set up the project, but it will most likely cause problems.

What you have described is not possible. If the bridges are set up to send messages to adjacent networks then any channels using the same group address on both network will always be controlled together <u>unless</u> you are sending messages explicitly to specific networks and not relying on the bridge to forward the message.


I suggest you read this document which will explain it all to you.
