7.8 General information on logic calculation
The logic controller calculates generated logic cyclically. The default engine cycle time setting is 200 ms
but this can be increased if required. See
Cycle time .
Logic is always calculated from the inputs to the outputs (left to right). There is no loop capability.
Fig. 9: General information on logic calculation
A calculation cycle calculates the entire logic. New values (e.g. from the KNX bus) available at the start of
the cycle are taken into account.
7.9 Inverting inputs and outputs
You can invert 1-bit inputs and outputs by double-clicking on the relevant I/O.
