changes from green to red. A second short press will start the CODESYS application. The Run /
Stop LED changes from red to green. If the button is pressed and held for more than 5 seconds, a
“Warm reset” is triggered. After the time has elapsed, the Run/Stop LED flashes quickly and the
button can be released. The controller is now in the reset state.
Service mode
The controller must be switched off to enter service mode. The button is then held down and the
controller is switched on again. The button must be kept pressed until the Run/Stop LED flashes
yellow every two seconds.
