"Greater or equal" module details
20.3.14.1
Behaviour
The module compares the values at the inputs. If the value of the
Input 0
is greater than or iden-
tical to the value of the
Input 1,
the result 1 (logical "true") is output on the
Output 0
. Otherwise
the output value is 0 (logical "false").
Output 1
always outputs the result inverted.
If necessary, incoming values are converted into the internal data type of the module before the
comparison (see conversion table below). Thus, observe the selection of a correct internal data
type!
The comparison is dependent on the internal data type of the module and is executed in the fol-
lowing way:

the module.
Via the

value shall only be sent if the result of the calculation is different to the previ-
ously calculated result.
