If your controller is a Visual 3 controller, it has a reset button you can use to bring the controller out of fault mode. Beside that. A Visual 3 controller should ALWAYS run with firmware 03.03.44 or later. Otherwise you risk it entering boot loop, which you can't recover from. Have you tried to upload the program using USB? Failing to upload a large program over network, is often caused by short network outages. If your controller is a Visual 3 controller there is a risk that you have one of the controllers with an unstable network interface. If you can reproduce the problem you can get the controller replaced by calling Schneider Electric.
