Posted 25 Jan 2017 Sounds like you need to configure the drivers for the connection. Are you using a Modicon-supplied cable or some aftermarket USB to serial adapter? Share this post Link to post Share on other sites

Posted 26 Jan 2017 I have not touched one in about 14 years. But I know the Unitelway driver configuration utility used to be located in the Start menu, so check there. Or perhaps search for Unitelway driver installation. Share this post Link to post Share on other sites
Posted 27 Jan 2017 1st close pl7. Then connect cable to pc and plc. Set cable to multi If you plug in the cable go to control panel-------system----hardware---and look if driver detected cable in ports Then go to windows start----schneider electric (or modicon on older software)------drivers manager Then click on unitelway driver--------configuration-----select the default and edit Select the com port. It should have the cable name next to the com number and showing ready. save apply and driver should reset Open pl7 and try again Share this post Link to post Share on other sites
