Hello mustang; How are you trying to do the configuration? Is the WinCC flexible project integrated in Step 7, or standalone? In any case, what you have to remember is that in the Profibus configuration, the HMI panel is not a slave, but a Master Class 2. A master class 1 (a PLC for exampole) holds a complete configuration of all slaves on its network, to establish the cyclic comm parameters; a master class 2 does not hold a static configfuration: it picks up the token from other masters, and requests the data it needs from them s=as it needs it.. For the MP277, Profibus parameters are not setup in Step 7 (HWConfig) but in the WinCC flexible project. Here is a link to the MP277 with WinCC flexible. It has a chapter on profiubus configuration, dowenload and transfer: http://support.automation.siemens.com/WW/view/en/23337820 Hope this helps, Daniel Chartier |
