Hello Hussain; The ports on the S7-200 are all RS-485, and the USS protocol uses this RS-485 interface. So you will need a RS-485 to RS-232 converter to connect to your drive on RS-232, if you are sure it uses the USS protocol (I have never seen it used on RS-232, myself). And the USS protocol ios dedicated to drive control, not for communication with PLCs. Have a look at the description of the USS protocol: Specification: Universal Serial Interface Protocol USS Protocol Would you mind giving us some information on these PLCs, maybe someone here has experience with them. Hope this helps, Daniel Chartier |
