Posted 9 Jul 2019 Thanks Jay Anthony & gtsuport. Is the cable shown in my post is ok? it is CN 226. Jay Anthony you said Switch 5 is on & Port Settings to 9600, E, 7, 2. So This setting is for CN 226 cable? What if i use RS232 to USB? Is there different settings for this cable? & By using RS232 to USB, am i able to online Plc & save program file to my PC?

Posted 9 Jul 2019 Yes, the CS1W-CN226 should work. USB to RS232, not all adapters works correctly. You can try to see if you adapter works. If not, I would suggest the USB CN226 cable from www.plccable.com https://www.plccable.com/omron-plc-programming-cable-usb-cs1w-cn226-cs1wcn226-usb-version/ Jeff Share this post Link to post Share on other sites
