Write value to another LM without KNX IP

[savaskorkmaz]

Hi,
I have point in my LM (LM-1) which is a 255 byte string type point. When I change value of this point, I want to write to another 255 byte string type point which is located in another LM (LM-2). I cannot use KNX IP futures or something (Because there are same KNX addresses in another LM's) 
I need a script which write value to another LM contains IP address of LM and KNX Point address. 

Thanks,
