S7-200 Siemens.

Go into Microwin and click the communications button, then tick the search all baud rates and hit the double click to refresh icon

I assume the s7200 port is not in free port mode though.

The S7-200 should come up in the right pane showing its comms.
 
Dave,
now I am able to upload the program but then put the machine in auto mode and could not see any change on the scan and even could not see any change on the color of each network,it seem like is not working.Please advise.

Thanks a lot.
 
For monitoring online, go to debug > start program status


The S7200 online help is really good for this sort of stuff :) !
