MP277 and routing

At the moment my MP277 is connected by profibus to a Cpu 317-2 PN/DP 6ES7 317-2EK13-0AB0 V2.6. To this 317 cpu, another exactly the same cpu-type is connected by a PN/PN coupler.
Can the MP277 acces variables in the second 317 cpu (over the PN/PN coupler).
If possible I suppose it is by routing, but how do you setup this routing, which settings?

A PN/PN coupler is used to safely isolate to PN networks from each other, so only the configured IO can be transferred between the two networks.
If you could actually access a CPU on the other side of the PN/PN coupler, it would mean you could just as well remove the PN/PN coupler.

Thats just my thought. Dont know if there is a way to reach past a PN/PN coupler.
