Posted 18 May 2016 Hi Everyone: I want to comunicate 4 inverters 3G3MX2 through RS485 (modbus) to a CP1L-EL20DR-D. I remeber that Omron has several FB to use between some PLCs and Inverters. I wonder if Omron has developed a specific FB to communicate these models, and if it so, where can I find them. Any of you have knowledge or can provide me these FB? Thank you for your support.
