Modbus TCPIP

Project :

Develop and test Modbus TCP/IP communication protocol using existing circuit boards:

1x Mother board,

1x communication board c/w 1 RS232 and 1 x RS485 and Modbus RTU 127 addresses

1 x metering unit board

All boards are communicating with CAN BUS.

The software is actually done with MPLAB 7.2, using C and compilation is executed with MPLAB C30 2.02. All tests are done with Modscan32.


1- Extend the Modbus addresses from 127 to 255 in the existent software. Implementation test of this phase.

2- Implement the TCP/IP stack compatible with the used microcontroller. Stack implementation test

3- Implement Modbus TCP/IP protocol and test.

4- Translate the existing Modbus RTU stack to TCP/IP and its implementation. Test of the implementation

5- Implement the HTTP server for WEB access configuration and its test.

6- Web pages development, implementation and test on of all parameters configurations via the web pages

7- Implement software upgrading downloads via TCP/IP including the implementation of the FTP in the software, FTP server in the TCP/IP stack. downloads test from remote stations.

8- Documentation of all the above
