[?]: S7315/CP 343-1 LEAN communicate with S7414H/CP443-1

[charles_ch_tan]

I have tried to connect a CPU S7-315 with CP 343-1 lean to CPU S7-417-4H via CP443-1 through ethernet connection.
I tested the communication and found out that I can only get maximum 2 links up and only around 200bytes read/write per link.
I would like to find out from you, if other types of CP 343-1,
such as the ADVANCED or FULL version is possible to create more links with CPU417 ?

The communication links between CPU315 and CPU417 is done through RJ45 cable,
using ethernet ports on both CP343-1 and CP443-1, and hence Internet Protocol.
Each link can transfer up to 160bytes (or 240bytes ??) of data in one direction, and multiple links are supposed to be possible.
I am expecting 10 links to be built up.
My customer has purchased the CP343-1 lean version, and we tested the communication, and only up to 2 links is possible.
Before he purchased CP343-1 full version or advanced version, we want to be sure that it can build up to 10 links with CP443-1.

How can make more Link?

Hope some one can help me.
