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 application program exists.
• 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 application program is running.
> The LED flashes green with 2 Hz.
The LED can be controlled differently by the application program → FB SET_LED (→ page 198).
A transition from this state into one of the following states is possible:
• INIT (after power-on-reset)
• STOP
• ERROR
• FATAL ERROR
>
ERROR state
8290
A transition into this state is possible in the following cases:
• if the supply voltage is too low.
In the ERROR state:
> The outputs of the device are switched off.
> Processing of the application program is stopped.
> System parameters are saved.
> The LED flashed red with 5 Hz.
A transition from this state into one of the following states is possible:
• INIT (after power-on-reset)
• RUN
• STOP
• FATAL ERROR
>
FATAL ERROR state
8289
A transition into this state is possible in the following cases:
• memory error (RAM / Flash)
• exception error
• runtime system error
In the FATAL ERROR state:
> The outputs of the device are switched off.
> The application program is terminated.
> The runtime system is terminated.
> The LED lights red.
A transition from this state into one of the following states is possible:
• INIT (after power-on-reset)
