I had a problem with a HY-TTC 580 ECU (CODESYS). The cycle time in the main task was changed from 10 ms to 1 ms and now the application can not run. Even the ethernet comunication doesnt work so I can not download a new program. The CAN bus is sending messages so I think it should be a problem with the ethernet initialization. Is there any kind of manual hard reset that doesn´t need a direct connection with the ethernet bus?

Start the PLC in the Bootloader mode with the TTC-Downloader.
Click Connect in the TTC Software, if you see the Message Box to Perform the power cycle, plugin and the see the Magic.
Or
Connect the Out +5v1 and +5v2 to ground, so the Device Boots in Bootloader Mode with Default IP and Default Settings. No Application will start with the 2 Wires to ground.
Then erase your Application with the Downloader.
