[FONT=Times New Roman, serif][SIZE=3]Dear Friends,[/SIZE][/FONT]

[FONT=Times New Roman, serif][SIZE=3]In our application we are planning to use Modbus TCPIP communication. This communication is between [/SIZE][/FONT][FONT=Times New Roman, serif][SIZE=3][B]HMI[/B][/SIZE][/FONT][FONT=Times New Roman, serif][SIZE=3] and [/SIZE][/FONT][FONT=Times New Roman, serif][SIZE=3][B]LPC1769[/B][/SIZE][/FONT][FONT=Times New Roman, serif][SIZE=3] Microcontroller. I am having idea about TCPIP in TRANSPORT layer but this Modbus TCPIP is communicating in APPLICATION layer.[/SIZE][/FONT]
[FONT=Times New Roman, serif][SIZE=3]So is there any example code for [/SIZE][/FONT][FONT=Times New Roman, serif][SIZE=3][B]Modbus TCPIP??? [/B][/SIZE][/FONT][FONT=Times New Roman, serif][SIZE=3]If there plz can you give me.[/SIZE][/FONT]
[FONT=Times New Roman, serif][SIZE=3]If you have any useful data and links about [/SIZE][/FONT][FONT=Times New Roman, serif][SIZE=3][B]Modbus TCPIP,[/B][/SIZE][/FONT][FONT=Times New Roman, serif][SIZE=3] Plz give me.[/SIZE][/FONT]


[FONT=Times New Roman, serif][SIZE=3]Thanks & Regards,[/SIZE][/FONT]

Dear Sir,



Thanks for your replay,



I hope it will be useful. Is this code is general for any controller or specific to any particular controller???



Is there any other general Ethernet sample code for LPC1769.Because first I want test Ethernet link and communication between PC and LPC1769 board.


Thanks & Regards,
Hareesha
