You said it works before, with exact the same cable? Is it a 9-pin-female to 15-pin-male? It have to be like theone is described in Communication Manual, Appendix E, E-10 http://support.automation.siemens.com/WW/view/en/1137086 The one following page is also possible, but mostly the serial port is with 9 Pins. On your panel you are on IF2? (config/printer) And make sure that no other Application is lock the COM-Port. For example direct after running Step5 with onlinefunctions, it may be the serial interface is still in use and no other Application is able to use it. Or an modem-driver etc. MPI/DP-Download works only when you have a configuration in the panel running S7-Protokoll. Otherwise the driver for this download is not loaded in the panel and not possible. |
