6.3.9 Dummy function
Fig. 23: Timing diagram for Dummy function
1)
In case of “Function fault“ “Function result“ is not necessarily set.
Note
The measured timing periods were determined with12 Mbit/s Profibus.
These timing periods can vary with different transmission rates and bus
systems. The cycle time of the PLC has not been taken into account.
6.3.10 Reset Function fault
Fig. 24: Timing diagram for reset function fault
1)
In case of “Function fault“ “Function result“ is not necessarily set.
BOUT8.3 is not reset if a critical systems fault is present. Examples are memory fault, power
failure, or low voltage. Critical faults cannot be reset via the process channel. Theses faults must
be reset via keyboard.
Note
The measured timing periods were determined with12 Mbit/s Profibus.
These timing periods can vary with different transmission rates and bus
systems. The cycle time of the PLC has not been taken into account.
