8.7 logical functions
3 logical functions are available.
A logical function consists in generating an output command resulting
from a logic operation comprising up to 3 input conditions.
Each input (fully configurable) is compared with a preset value
depending of the communication objects size selected. The element
of comparison between the preset value and the value received into
the input communication object is also configurable (equal, different,
higher, lower, etc.).
The logical result of each comparison (true or false) is then operated by
up to 2 operators (depending on whether different inputs are used or
not) in order to generate a logic operation result. This result is used to
trigger the output telegram (fully configurable).
The output telegram value can be the logic operation result or a preset
value (the preset value size depends on the chosen output communi-
cation object size). Also, there is a condition (configurable) that triggers
the output telegram sending (see parameter “Output SendCondition”).
