Posted 24 Aug 2016 (edited) Hello, i will be grateful if someone has simple MODBUS RTU program that can be used as a learning program. I have 2x Q03UDECPU and 2x QJ71MB91, and i want to send some bits/integers (master-slave). I'm using GX Works 2 Best Regards, Luka Edited 24 Aug 2016 by Luka0204 Share this post Link to post Share on other sites
