Hello Candra; The easiest test you can do is to open the HWConfig editor; offline, you should see the drive as one of the Profibus slaves configured on the DP master of the CPU. If you go online in HWConfig (use the glasses icon in the toolbar), the editor shows you the status of the CPU and the Profibus slaves. Disconnected or faulty slaves will be shown with a red cross symbol. If the drive has a green contour and no red cross then it is recognized buy the CPU and active. You can check the addresses attributed to that slave when you click on the icon representing it, a table appears below with the slave details, including I and Q addressing (generally above 256, or even 512, depending on your CPU). You can then check where these addresses are used in the program (use PIW and PQW addressing). If your addresses were given as 256..259, for example, PQW256 would constitute the address of the Control word (binary commands to start/stop, for example). of the drive, PQW258 would be the address of the Speed Reference word (to control the speed). PIW256 would be the Command Status word of the drive, PIW258 would be the Speed status word. All this is explained in detail in the following manual for Profibus communications for a Micromaster drive:
