4.1 Operating states
1075
After power on the ecomatmobile controller can be in one of five possible operating states:
4.1.1 INIT state (Reset)
1076
This state is passed through after every power on reset:
> The operating system is initialised.
> Various checks are carried out, e.g. waiting for correctly power supply voltage.
> This temporary state is replaced by the RUN or STOP state.
> The LED lights yellow.
Change out of this state possible into one of the following states:
 RUN
 FATAL ERROR
 STOP
4.1.2 RUN state
8287
A transition into this state is possible in the following cases:
 from the INIT state (autostart) if the following conditions are met:
 The operating voltage has reached a minimum value. AND:
 The IEC application regularly runs cyclically.
 From the STOP state:
 via the CoDeSys command RUN.
 The operating voltage has reached or exceeded a minimum value.
In the RUN state:
> The runtime system is running.
> The operating system is running.
> The application program is running.
> The LED flashes green with 2 Hz.
> The LED can be controlled differently by the application program.
