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.
Master behavior at CPU RUN
n The global control command "Operate" is sent to the slaves by the
master
. Here the DE-LED is on.
n Every connected DP slave is cyclically attended with an output
telegram containing recent output data.
n The input data of the DP slaves were cyclically transferred to the
input area of the CPU.
