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 and V130 plc's and Samkoon HMI's.

 

 

 

 

Thanks for the guidance. Do you have an example program that you can give me?

regards

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.
