#159230 - modbus frame error Responding to: ???'s previous message |
I am using slave as 8051 microcontroller (c8051f000),
I completed and tested the code and its not working. Iam using simulator as a master and i am receivng slave id and function code at controller rx pin. but when i am sending data to master iam getting frame error and read error, i suspect that it might due to timing and I spent few days but I am still not able to solve it. This project is to receive command from any PC (serial port 0) with RTU format.plz help to solve this thnks saritha |
