Wiring test

If the configuration of the operation selector is reset subsequently, you must first
ensure that it is set to Auto. Otherwise, the output constantly remains "On" or "Off".
9.6 Wiring test
During the wiring test, the logic block outputs can be directly switched via the
control switch. During the wiring test, delay and on times are inactive.

Priorities

For logic operations, the following priorities apply:
7. ON/OFF during the wiring test.
8. Off by "Off time minimum"
9. On by "On time minimum"
10. Off by Switch-on delay
11. On by Switch-off delay
12. On by Operation selector
13. On by logic inputs.
9.7.1

Notes

• There is no hysteresis for an analog input of the logic block where the switching
value On = switching value Off.
• 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 handled sequentially in accordance with their instance
number, that is, first logic 1, then logic 2 through logic 10.
• If outputs are looped back, e.g. from the output of logic block 7 to the input of
logic block 2, the result at logic block 2 will only become available with the next
handling cycle.
