20.3.18 Area tester (external) module details
20.3.18.1 Behaviour
The module checks whether the incoming comparison value on Input 0 lies outside two limit
values. The limit values are defined by the Input 1 and the Input 2. If the comparison value is
outside the limit values, the result 1 (logical "true") is output on Output 0. Otherwise the output
value is 0 (logical "false"). Output 1 always outputs the result inverted. If the limit values are
invalidly configured (e.g. upper limit less than lower limit) the result 1 (logical "true") is output
on Output 2.
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:
