But it can communication with your PLC and HMI.
USB Adapter CN is a high-tech adapter similar , support USB of computer to PROFIBUS/MPI/PPI communication, USB Adapter CN adopt power supply from USB port,use the low-power low-voltage chip,even if the USB port power low down to 4V，it still can ensure the stable and reliable work of the adapter. RS485 interface(PROFIBUS/MPI/PPI) of USB Adapter CN is the standard interface as same as the CP5611/CP5512, the 6PIN and 5PIN of DB9F socket output 5VDC power which can supply the power for the termination resistors. Besides it can be used for S7-200/300/400 PLC,it also can be used for HMI,CNC etc other third party equipments,support long distance communication,allowed cable length meet the profibus standard.

USB Adapter CN installation
You can put the USB Adapter CN on your desk or install it on the rail of control cabinet.It has the mounting bracket accessory.User can self-make an Aluminum board with thickness 1.5mm～ 2.5mm,then install the adapter on the S7-300/400PLC rail or 35MM standard rail.
PROFIBUS/MPI/PPI interface connection cable
There is a pc of 5 m cable attached with the adapter,it’s used to connect the USB Adapter CN and PLC,correspond to Siemens 6ES7 901-0BF00-0AA0,as shown below:
Long distance communication
USB Adapter CN power is provided by the USB port,voltage is +5VDC±15%,150mA,not from RS485 interface of PLC.Thus the adapter can also be used for the other DP/MPI/PPI interfaces without 24VDC power output.Besides the RS485 interface of USB Adapter CN is as same as Siemens CP5611/CP5512,you can insert the profibus connector to achieve the long distance communication,and provide the power for the termination resistors of profibus connector. Different baud rates allowed the largest communication distance meet the PROFIBUS standard,as shown in the following table:

Driver CD 1PC Operating System requirement The following operating system is required on the PC Windows 2000 Windows XP Professional Windows XP Home Windows Server 2003 Standard Edition Windows Vista Windows 7 You need to install STEP7 software for S7-300/400PLC, STEP7-Micro/WIN software for S7-200PLC when you use USB Adapter CN to communicate.For other devices like HMI,CNC to communicate,it’s also required to install the corresponding application softwares. Start to use USB Adapter CN Install driver After you install STEP7 or STEP7 Micro/WIN etc softwares on the PC,you still need to install the Siemens original PC_Adapter_USB driver, the driver is included in the CD. You also could download the latest version PC_Adapter_USB driver from Siemens website, the link is http://www.ad.siemens.com.cn/download/docList.aspx?TypeId=5&CatFirst=1&PageIndex=4 Check whether the USB Adapter CN can work well after you install the driver,right click”My computer”->Property->hardware->device manager,plug the USB Adapter CN in the USB port of PC,device manager will appear a new device as shown in the following red box,which show the hardware and driver work well.
It will appear the “USB” option in the “local connection” of “set PG/PC interface” in the Step7 software after you finish installing the driver,and then choose this USB option. Set PG/PC interface: Run STEP7 or STEP7 Micro/WIN software,click “Set PG/PC” button and then it will show the following choice list: - PC Adapter (Auto) （This option will be shown only after you install the STEP 7） - PC Adapter (MPI) - PC Adapter (PPI) （This option will be shown only after you install the 7-Micro/WIN） - PC Adapter (PROFIBUS) If it doesn’t show the above list,please click "Select..." button to install or remove the interfaces. Select one interface in the list.click”property”,it will appear “USB” option in the “local connection”,choose this “USB” option and then click “OK”.
In the next the connection between USB Adapter CN and DP/MPI/PPI interface of PLC is OK,and you could do the downloading,uploading and monitoring operation. STEP7 software setting when it communicates with MPI interface of S7-300/400PLC: Connect USB Adapter CN to MPI interface of S7-300/400CPU. Enter Step7 software main interface（SIMATIC Manager）,click “Set PG/PC interface”under “option”menu to enter PG/PC setting interface. 1.Select “PC Adapter（MPI）”, click”property” button to enter MPI interface parameters setting.
2.Click the top “MPI” option,set the adapter MPI interface parameter,choose the baud rate 187.5Kbps or 19.2Kbps or 1.5Mbps,this baud rate must be the same as the PLC MPI interface baud rate.If you don’t know the PLC MPI interface baud rate,you could choose “PC Adapter （Auto）” to check.Other parameters are default,click “OK” button to return the previous menu,click”OK” to return the main interface.
