8.7 Commissioning and Start-up behavior
In delivery the CPU is overall reset. The PROFIBUS part is deacti-
vated and its LEDs are off after Power ON.
The DP master can be served with bus parameters by means of a
hardware configuration. As soon as these are transferred the DP
master goes online with his bus parameter. This is shown by the RUN
LED. Now the DP master can be contacted via PROFIBUS by means
of his PROFIBUS address. In this state the CPU can be accessed via
PROFIBUS to get configuration and DP slave project.
If the master has received valid configuration data, he switches to
Data Exchange
with the DP slaves. This is indicated by the DE-LED.
After PowerON respectively a receipt of a new hardware configuration
the configuration data and bus parameter were transferred to the DP
master. Dependent on the CPU state the following behavior is shown
by the DP master:
Master behavior at CPU STOP
n
The global control command "Clear" is sent to the slaves by the
master. Here the DE-LED is blinking.
n
DP slaves with fail safe mode were provided with output telegram
length "0".
n
DP slaves without fail safe mode were provided with the whole
output telegram but with output data = 0.
n
The input data of the DP slaves were further cyclically transferred
to the input area of the CPU.
