I am unable to connect to KPT1000 Basic DP panel using PC Adapter USB 6ES7 972-0CB20-0XA0. There is a panel, PLC 313-C 2DP and one TS adapter on MPI network. Using Accessible nodes I am able to see all three devices with their addresses (1, 3 and 31). In the PG/PC interface I have set MPI address to 30. I am able to connect to PLC, transer S7 project without any problems. I am also able to start runtime simulator on WinCC flexible (2008 sp2), which pulls data from DBs without any problem. I have gone through this link http://support.automation.siemens.com/WW/view/en/23787153 and everything looks ok in my settings. There is also this note on above link Direct transfer from the PC to the Windows-based panel via a PC adapter (RS232 -> MPI/PROFIBUS, USB -> MPI/PROFIBUS) is not supported. This can also be backed up with the information from following link: http://support.automation.siemens.com/WW/view/en/19109408 where under 6) it states PC/MPI-Adapter and USB/MPI-Adapter are not released for transfer. However, on this link http://support.automation.siemens.com/WW/view/en/21912699 it says: Notes on the USB PC adapter (6ES7972-0CB20-0XA0) The USB PC adapter provides an MPI/DP interface via the PC's USB interface. More information is available in the manual in Entry ID: 16983464. This cable is released only for the devices below for project transfer and OS updating.
I have also tried connecting with TS adapter, but failed to succeed. I still can see all MPI devices, I am able to access PLC, but not Panel. using both adapters, when I try transfering project, after compiling is finished, and after message Preparing connection to device I get this message A connection could not be established. Please check your settings, ports, cable etc.. Usually when I have bad configuration it takes some time (10+ seconds) to display connection error. In this case, this error message is displayed immediately after "Preparing connection to device". Any advice about this problem? Thanks, Goran |

Dear Goran, Can you explain what transfer settings you have selected in WinCC flexible? Best regards, Wizard |

Dear Goran, In PG/PC interface did you tick the option "PG/PC is the only master on the bus"? Best regards, Wizard |
