I guess you are using integrated profibus port of the CPU. If you have all the IOs of drive configured within the image area of the CPU, then you do not need to use any SFC/SFB. You can directly access data using inout addresses. (Eg: IW20). Even outside image area, if you need to use SFC depends on the data consistancy of the profibus IO data. if it ismore than4 then you needto use SFC14/15, otherwise you can address them (eg: PIW256) check the FAQ and goto section "The "Peripheral addressing". http://support.automation.siemens.com/WW/view/en/18325417 If you need more help, please post a screen capture ofHW config screen withdrive IO area details. |
