Hello,
it's been a month since I worked on this project that implemented a communication interface in C # that can send and receive data between my pc and axis control via serial port.
MCS axis control is programmed to receive or send data.
here is the program:
C#:

to start communication, MCS expects a code 10h, 11h, 12h or 13h (corresponds has stained the program below) followed by three characters on program number to start the treatment.
So I have to add to this mailing my program for the transfer function. or I have to add the line:
C#:
C#:
[COLOR=#880000]// if bouton reception[/COLOR][COLOR=#000000]
serialPort1[/COLOR][COLOR=#666600].[/COLOR][COLOR=#660066]WriteLine[/COLOR][COLOR=#666600]([/COLOR][COLOR=#008800]"\u000D"[/COLOR][COLOR=#666600]);[/COLOR][COLOR=#000000]

[/COLOR][COLOR=#880000]// if bouton envoyer[/COLOR][COLOR=#000000]
serialPort1[/COLOR][COLOR=#666600].[/COLOR][COLOR=#660066]WriteLine[/COLOR][COLOR=#666600]([/COLOR][COLOR=#008800]"\u000A"[/COLOR][COLOR=#666600]);[/COLOR]

I get connected to the shaft drive.
I have some problems:
1- I do not get all the data together, you have every time I press the button to return to receive the data.
I work with dataReceived for receiving data.

2- for sending I was unable to sync between the send button and the button (dbtcom = on, press F6 User waiting) I have to recover the signal Rx serial port.
