Submitted by Udit Kumar on

Hello, I'm trying to make this project but in simply modbus software I'm unable to get response how I should check the fault.the link of the project is given below.

Check the connection first. Are you using exactly same circuit? Did the code compiled properly?

Thankyou very much for responding

As in the project there are four major parts 1. arduino /2.LCD / 3. USB to RS 45 converter module/ 4. MAX485 TTL to RS-485  /5Servo motor . I'm not using servo motor , LCD interface is OK, Circuit Connections are OK, connections of USBRS485 and MAX TTL to RS is also correct. but i can't say whether they are working or not.
