Hi All,
I am using Microchip PIC16F877 as Modbus RTU and I have stored 0x55h value in the 0x20h address. I am tring to retrive the 0x55h value through the hyper-terminal using the Function Code 03. Kindly suggest me about the Modbus Data Mapping. Should I refer to 0x20h in the modbus request or should I use the Modbus Mapping
Thanks
Maran
