Operation principle
The comparison can be done in two ways,
1. Between 2 inputs, INPUT and REF
2. Between INPUT and the SetValue setting
The selection of reference value for comparison can be done through setting
RefSource. If RefSource is selected as Input REF then the reference value for
Type Default Description
REAL 0.000 Input value to be compared with reference value
REAL 0.000 Reference value to be compared with input value
Type Description
BOOLEAN Input value is equal to the reference value
BOOLEAN Input value is higher than the reference value
BOOLEAN Input value is lower than the reference value
