Hello, I would like to implement MODBUS TCP on a PIC32. I am using the Microchip TCP/IP Stack and looking for some C- Source Code. My development board is the Explorer 16 from Microchip with a PIC32MX360F512L and an ENC26J60 Ethernet Pictail, so the implementation should be possible. The plan is to control the PIC from a PC (for example via Labview). If anyone has experience with Modbus or has other information please let me know. Every comment is welcome. Thank you!
Hello, I make Modbus RTU slave for PI32 via UART. My development hardware is PIC32 Demoboard. Microchip TCP stack is very good, stable, but too big. For data transfer with PC is necessary Modbus TCP server. Beta version will be ready cca end of January 2010. Zdenek
Thank you for your help. If the Microchip TCP/IP stack is too big what else would you recommend? Happy new year. Bender
No no ... TCP stack ist big, but stable. Would crasy writing new TCP stack. Is impemented in LabView Modbus RTU via serial line ? If yes, I send my Modbus RTU library via UART. It´s temporary solutoins, before first version of Modbus TCP.
Yes, there is an ModBus serial (RTU,ASCII) and an ModdBus TCP implementation in LabView.
If you are doing an ModBus RTU slave on PIC32, you could be interrested in this: http://www.opensourcepic.org/modbus.php Its a Modbus RTU and ASCII implementation on freemodbus. But there is no TCP, so it does not help me. I hope it helps you.
