Modbus TCP on FRDM-K64F

[nicholas_yameen]

Hello,

Has anyone experience using Modbus TCP on FRDM-K64F using mbed?  I want to be able to use ethernet to talk Modbus TCP.  Are there any libraries that will work for this platform?

Thank you.

Hello Nicholas,

I have the some problem, so I'm loooking for Modbus over TCP to implement on K66, but since now I didn't find nothing.

Did you find something about MODBUS/TCP ? On uTasker could have something but is too expensive

Thank you so much.

Hi Marco

The uTasker project includes ASCII/RTU/TCP Modbus (master/slave/bridge/gateway) for all Kinetis parts (10 year industrial use).

If you are a non-commerical developer who needs it for personal work/research just contact me so I can give you access to the full version.

If you are a professional with financial difficulties you can also apply for a free commercial license* which will allow you to have immediate operation and support (on this forum) for a single product development so that you quickly become profitable again.

Regards

Mark

Hi Nicholas

There is an off-the-shelf solution for Modbus TCP on FRDM-K64F at http://www.utasker.com/modbus.html (TCP master/slave and RTC/ASCII UART master/slave with bridge and gateway operation).

It doesn't use mbed, where you will probably need to port something like FreeMODBUS with lwIP if you need a free one.

If you need a solution by tomorrow just use the uTasker one since it works out-of-the box and has been industrially proven since 2009 (including in the units controlling the video screens in the Claw at U2's 360° world tour !).

Hi Mark,

Hi Nick

Have you manage to solve your project's requirements in the meantime?

Hi Mark,

I have tested the freeModbus library and decided not to use it.  Instead I have used modbus++ and changed it to mbed.

Thank you,
