10.8.9 Priorities
For logic operations, the following priorities apply:
1. On / Off during wiring test
2. Off by "Off time minimum"
3. On by "On time minimum"
4. Off by switch-on delay
5. On by switch-off delay
6. On by operation selector
7. On by logic inputs
10.8.10 Notes
If with an analog input of the logic block the switching value On = switching value
Off, there is no hysteresis.
If an error occurs at a configured input, the "Off" state is issued for the entire logic
block.
If only inputs are configured with logic A, logic C is ignored and the signal of logic A
is sent directly to the output.
If only inputs are configured with logic B, logic C is ignored and the signal of logic B
is sent directly to the output.
The logic blocks are processed sequentially in accordance with their instance
number, i.e. first logic 1, then logic 2.
If outputs are looped back, e.g. from the output of logic block 2 to the input of logic
block 1, the result at logic block 1 becomes available only upon the next handling
cycle.
