11.2.2 Initialisation
After the supply voltage has been connected, the initialisation of PROFIBUS
Gateway or PROFIBUS GatewayECO starts:
l The internal functions of the module and the communication via the
backplane bus are checked.
l If communication faults occur on the backplane bus, the module changes
into the "STOP" state. After approx. 2 seconds, the initialisation is started
again.
"STOP" status
PROFIBUS master sets
outputs to "0" and accepts
the set device address
