Emergency Flash

In case of a bus error the internal watchdog is activated. The terminal can be configured in such a way ("Enable emergency flash" = 1, see Index 0x8002:04) that it outputs a pulse sequence in this state - the Emergency Flashing. This sequence can consist of a maximum of 6 pulses. The On/Off times are set in the object "DOX Flash Timing".

Note that a complete pair of "ON-Time" and "OFF-Time" must always be set. At the first time that is written with 0 the terminal starts again automatically with the first pulse.
