Posted 20 Feb 2017 It cannot transfer all IOs between PLC's. There is a limitation (don't remember right now) of how many IOs (bytes) can be transferred. Check the manual. An option to CC-Link is CC-LinkIE which has room for a lot more IOs. Share this post Link to post Share on other sites

Posted 21 Feb 2017 Hi aakash, I have not quite understood what exactly you have trouble with. But I maybe think you are missing some settings for the remote I/O-stations. I seems at default settings. /Dariusch Share this post Link to post Share on other sites
