CCS/MSP430FR2155: MODBUS Message RTU Framing Missing Responses

Part Number: MSP430FR2155

Tool/software: Code Composer Studio

Hello All,

I am working on MSP430FR2155 microcontroller, In that I am using MODBUS RTU. In my controller I am using Uart to communicate with MODBUS, but in that I am not getting proper responses. I am checking the result on Modscan32, Valid slave responses are lesser then Number of Polls. How can I overcome this problem, Please suggest?

Thanks,

Sandhya
