Posted 21 Dec 2017 Hello everyone. I need to make connection between plc fx3u and GOT panel (still not sure what model it will be) on distance between each other +-1km. Which connection should i use? Ethernet? 422? 485? Share this post Link to post Share on other sites
Posted 21 Dec 2017 I would go for ethernet but you will need two switches with fiber to get to such a length. 1 person likes this Share this post Link to post Share on other sites
Posted 21 Dec 2017 RS422 would do the distance it just depends on how fast you need to run the serial speed link to the GOT. 1 person likes this Share this post Link to post Share on other sites
Posted 22 Dec 2017 (edited) Thank you for your answers. I need a trend of current value on GOT nearby motor, but closest plc is located 700m-1km away from it. So idk, i think it doesnt require fast speed link or i wrong? Edited 22 Dec 2017 by SolidRio Share this post Link to post Share on other sites
