jack_russel Posts: 3 Rating: (0)	Hello Hoss, Did you try the setting "search on all baudrates" under Communications before you started to find the CPU with the function "Double Click to Refresh"? Your settings are good. Be sure that the communication port on the CPU is not configured as free port : in that case try to switch to stop mode. Regards

hoss Posts: 3 Rating: (0)	Hello, Thank you all for your replies ! I'm using STEP7 MicroWIN V3, which is not able to search on all baudrates, like V4 or later. I really don't know what to do :s regards

candyengineer Posts: 218 Rating: (26)	Hello , All posts are right, Min is just as an idea , could you check the cpu port & cpu switch ? As wizard said, you can check the cable speed - look up to the dip switches (right behind the adaptor) you can configure as 19.2 And here is my settings, and it works. if you still have a problem, check your cable / cpu port working correctly or not.
