hi
I'm studying about Modbus.
I would like to see on a PC the data from a pic
with Modbus (programmed with CCS)
 
I  tried with the file suggested by Trump:  Roll Eyes
http://rapidshare.com/files/77291978/Modbus.rar.html

and some other:
http://www.modbus.pl/MTester.htm
http://www.modbustools.com/

 Cry in all the cases I can't read the  data.  Cry

obviously the configuration's parameters are identical
on both devices, PC and Pic



thanks  for every help

Luca,
Try with this master software for Modbus RTU.

No need to install, just copy into a folder and use. Enjoy!

You can use DAQFactory to test your devices, DAQFactory (Modbus Scanner) is free, and very powerful, this is link:

thank you very much for your help!

After various test done with all software, and using different firmware on pic

only http://mihd.net/ohfnyp  works correctly!  Roll Eyes

all configurations are identical

  Huh I don't understand the cause for that.  Huh

Probably you are  rightEmbarrassed

I think that all depends what says modbus.c

  Huh Is it  possible to find various modbus dialects??  Huh

I think there are two Modbus-Dialects.

ASCII and RTU

Don't use ASCII

In the CSS-Forum Neutone has made a fine Modbus-Software

I use the Tools from modbustools.com. They are fine. You see everything with this software!
