WinCC Modbus TCP/IP Channel Driver

Dear All
Has anybody tried using WinCC TCP/IP Channel Driver in WinCC to communicate Schieneder AltiVar 71 Soft Starters.

I got confused in creating New Connection in WinCC Modbus TCP/IP Channel Driver.

In the Connection it was asking CPU Type . I don't know what type of CPU that Soft Starter have.

Have anyone ever tried setting communication through WinCC TCP/IP Channel Driver and Schnieder Soft Starters.
