Recommended place to Install SL,LM in the KNX TP Topology

[khalil]

Hello 
In a building I have Main Line 1.0 and one Line 1.1 
Could I install the SL in Line 1.1, and does it Recommended?
Or should I always install it in the Main Line?

It all depends of the project. It can be in both places. Take in to account that LM also act as IP router.

But when I connect to the subline I cant program devises located in the main line.
I have Line coupler 1.1.0
Could this be solved by changing the coupler Parameters?

LM can program only TP line physically connected to it. If you add any filters below like line coupler then there is nothing LM can do. Probably Line coupler could pass it trough but I'm not sure. Line repeater would do.
