Hello,
The HiCON Integra requires the use of a custom program to achieve ATC functionality. You could either make the program as a custom script in Mach4, or you could use the HiCON Macro feature which allows you to write custom programs and download them to the controller.
If you wish to go with the HiCON Macro feature, we do have a tool changer sample program available on the website which you can modify to fit your needs.

Please feel free to reply if you have more questions.
