Hello,
I use a Modus Master and Slave between Arduino DUE,s
I want to add other functions such as:
Read_coil_status
Read_input_status
Read_input_staus
Forse_single_Coil etc.
I'm looking for an example with more function's as the standard library, because I am still unable to implant it
Or perhaps where i can find more information how I can add more functions.

There is a .pdf that presents and explains all the available functions you can have with SimpleModbus library:
To upload the library,there is an issue (I don't know why). But, all you have to do, if you want e.g. use your DUE as a MODBUS Master is:
Open a new IDE window, name it e.g. MyModbus, then click in the little arrow in the top right of the window and select New Tab (You will see a yellow band).
Name this New file SimpleModbusMaster_DUE.h , copy and paste this file from the library into your SimpleModBusMaster_DUE.h.
Do that again but this time for SimpleModbusMaster_DUE.cpp that you will save in your SimpleModBusMaster_DUE.cpp .
Copy the sketch of the example provided. Change the include to have:
#include "SimpleModBusMaster_DUE.h"
Because the library is now in the same folder as your Modbus example folder.
You can now modify the provided example sketch.
Hello,
First thanks for the response.
I have already the simple master and Slave Modbus installed it works, that is not the problem.
And I have already download the .pdf file with the explanation.
The problem is that the explanation is not entirely clear for my.
So I looking for the simple Modbus library to which some functions have already been added.
So I can see how you approach this.
I'm an new user, everything is not entirely clear for my.
Since MODBUS is a standard protocol, this tutorial is relevant for any MODBUS library:
OK thanks I'm going to see if I can continue with this.
I think it's not easy for my.
