PC and KAS UDP communication: C# example (Visual Studio Express 2013)
This example shows how to exchange data between a PCMM or AKD PDMM and a PC using UDP.
The attached KAS program works with the target controller and 2 AKD drives.
The PC-based program is written in C# and receives the axis positions from the controller. It is also possible to send text to the PC.
- Download the attached KAS program to the target controller (PCMM or AKD PDMM) and use the integrated control panel "Panel_UDP" for activating the connection.
- Enter the IP address of the PC (IP Client field) and push the Start Communication button. You have 40 sec to start the C# program and activate the connection before timeout.
- Start the C# program.
- Enter the controller's IP address and push the Connect button.
