I am not sure if this is the right forum, but I guess someone might be able to help anyway.
I have in a large project some problems with telegrams sent from SpaceLYnk. In this project we have 30 distribution boards, all equiped with one SL and a number og IP-routers that work as Line Couplers.
There is an override function that we need for all heating actuators that needs to be sent to every line in the project. If we connect the PC to a line and send the telegram from ETS, we can see that the telegram is forwarded on all lines. But if we go to the object list in a SL the telegram is only forwarded to the lines in the same distribution board as the SL is installed.
I have discussed this problem with someone from Schneider, and we were thinking maybe there is a difference in the multicast telegram sent from SL compared to when we send it from the ETS. Is there in some way defined how many switches a multicast telegram from SL kan be sent thru? If so, what is the number, and more importantly; can this be changed?
As it is now, to send a telegram from one distribution board to another, the telegram needs to pass thru 5 network switches.
Simplyfied network plan with only two DB's is attached to the post.
