Hello, I am getting this error when I try to connect to a program I made before. What should I do?

Hello,

Could you please elaborate on your issue? Are you trying to log into a CC100 controller with a program which is already loaded and running in the controller? Is the program which you attempting connection to changed from what is currently loaded and running on the controller? Did you add functionality to the program which requires additional license?

Bağlanmaya çalıştığınız program, denetleyicide şu anda yüklü ve çalışan programdan mı değişti? Programa ek lisans gerektiren bir işlevsellik eklediniz mi?

Yes, I want to connect to a working program. I did not add anything that requires a license.

If you can connect to the Web-Based Management page, please post what Firmware your controller has. The “Implemented Version: 0.0.1.0” seems odd to me, and I wonder if you have a custom- or beta- firmware installed.

firmware 21 was loaded. I was able to solve the problem by updating the firmware. But I think it shouldn’t do this. After all, the running program is loaded onto the CPU.
