I need a PC program to simulate the Modbus protocol. The PC should be able to work both as a Master and a Slave and in RTU and Ascii Modes...

In "www.windmill.co.uk":http://www.windmill.co.uk you can download commdebug.exe. It´s a tool to simulate modbus over rs232. You can write every frame byte and include
CRC.
It´s very usefull.

 

Ocean Controls at "http://www.oceancontrols.com.au/modview.htm":http://www.oceancontrols.com.au/modview.htm have a PC Modbus simulation program which can act as both a master and a slave and also communicate
both in the RTU and Ascii format.

 

I have had very good results using software from:
