When the boot-up process is
complete, the DEVICE LED switches
to green, while the
Cubicle
BUS
LED
switches to green or is extinguished,
depending on the connection.
If the BDA is not supplied power via
the
Cubicle
BUS
of the WL, it must be
activated via an external 24V DC
power supply. Siemens SITOP
24V DC power supplies are suitable
for this purpose.
Other 24V DC power supply units
that supply the required power can
also be used.
