Creatrios Posted December 6, 2016 Report Share Posted December 6, 2016 ESTIMATED GOOD, I AM CONDUCTING A PROJECT THAT CONSISTS OF COMMUNICATING A UNITRONICS V120-22-R2C WITH A SCREEN REDLION G310 BY BUS RS485 ASCII PROTOCOL, THE SCREEN ALLOWS TO WORK WITH THE PROTOCOL OF UNITRONICS PCOM ASCII MASTER, I AM PERFORMING TESTS WITH THE V120 TO SEND DATA AND THE I GET THROUGH AN RS485 BUS EMULATED IN WINDOWS BUT I CAN NOT COMMUNICATE WITH THE SCREEN. E REVISED THE PARAMETERS OF COMMUNICATION, THE MAPPING OF VARIABLE ... AND NOTHING. I LEAVE THE TOPIC. GREETS CREATRIOS. Quote Link to comment Share on other sites More sharing options...
Kikis Posted December 7, 2016 Report Share Posted December 7, 2016 Hello, If your screen supports modbus RTU, it would be very easy to establish communication via RS-232. I did this many times in the past with V120 - V130 PLC's and Samkoon HMI's. Quote Link to comment Share on other sites More sharing options...

Do you have an example program that you can give me? regards Quote Link to comment Share on other sites More sharing options...
Kikis Posted December 8, 2016 Report Share Posted December 8, 2016 Hello, I guess that your V120 will be the Modbus slave, so you can check the example included within Visilogic. There is also a Unitronics webinar about Modbus that will be very helpful. Regarding Redlion HMI, i can't help you as i have never used their products.
