Posted 16 Mar 2017 Hi Ankitjd 1. Pls check in your laptop/PC which COM port (COM1,COM2, COM3 etc) you are using to communicate to PLC. You can check it using Control Panel (Device Manager). 2. In your GX-Developer, Transfer setup, please change COM number depend on the result no.1 above. If still can not communicate, maybe the problem in your data cable or serial converter also may have problem. That my suggest Share this post Link to post Share on other sites
Posted 20 Mar 2017 Yes, as Azdi Mus said, double click 'Serial USB' in top left, and then change the COM port to whatever you're plugged into on your laptop. Then, make sure your transmission speed is correct (pull down below the COM port) Finally, there is additional parity, data bit and stop bit variables in the 'set up' part when using serial connection.
