Yes you are right. English is not my native language. Thank you for trying to help me) I have not yet reset the controller to factory settings. I just turned it off and on. Operating system 3rd as far as I know. I'm not near the controller unfortunately. On Friday I’ll be there and try everything I dug up on the Internet and what you recommend. C4 training is already in progress and I will soon have a certificate. As far as I know DHCP IP. Static not done yet. There are no conflicts in the IP either, as far as I know. The controller itself is connected to the network via lan. it worked fine, everything was fine until the controller was turned on and turned off.
After turning on, Composer finds the controller and connects, you can program whatever you want.
As soon as you execute a command or script, contact with the controller is lost and NEEO and T4 issue an error page; the composer breaks the connection with the controller.
But on the controller, 2 blue indicators are lit on the right, but on the top of the board,
when you look, a small orange indicator blinks. does this mean anything?
