Hi,

This is quiet annoying...

According to the information I found is USS-communication not implemented in the 313C-2PtP, that is it is not mentioned in the manual.
According to the CP340 manual is USS communication possible as well as with the ET200S 1 SI.

You can also use it in combination with an S7-200 (Library).

Information:

• Function Blocks, Examples and User Manuals for the ET200S 1SI Serial Interface
• PtP coupling and configuration of CP 340
• Specification: Universal Serial Interface Protocol USS Protocol
• USS:Closed-loop speed control with V/f characteristic control using PID controller operation and encoder
• Addressing multiple drives (MICROMASTER) via the USS protocol in the S7-200 program
• MM4: USS Protocol Description
• USS instructions in STEP 7-Micro/WIN32 with MM4 drives

And there is more information available on http://support.automation.siemens.com/WW/view/en.
