Hi,
I want to manipulate the data using Modbus protocol over UART and i decided to use PIC24 series microcontroller to implement this process. I studied little bit about MODBUS protocol, but in that their using MTCP gateway as a intermediator. but still i did't get that how to implement this protocol over UART.
There also two interfaces
1. RS232/485
2. Ethernet (TCP/IP)
Two transmission modes
1. ASCII mode
2. RTU mode
I planned to use via RS232. but i can't to decide which Transmission mode is convenient. please kindly some one give idea about this process.
