Settings for General Calibration Tasks - Calculate Dependent Characteristics
The following alternatives can be configured to calculate dependent characteristics using the user option Calculate dependent characteristics :
- You can choose whether to input into the following calculation unrounded (physical) or rounded (quantized) intermediate results as initial values.
- You can choose whether, in the event that limit values are exceeded or not met, to input into the following calculation the actual intermediate result or the intermediate results limited to the limit value.
The exact behavior when calculating in dependence on the set option will be illustrated using the example in the following table. The example contains the following variables:
- virtual_1: input variable for calculation
- dependent_1: dependent characteristic calculated using virtual_1
- dependent_2: dependent characteristic calculated using dependent_1
virtual_1 | dependent_1 | dependent_2 | |
|---|---|---|---|
COMPU_METHOD | ident | ident | ident |
Data type | SBYTE | SBYTE | SBYTE |
Limits | -127 .. +127 | -127 .. +17.4 | -127 .. +127 |
Computation formula | 2 | virtual_1 * 10.3 | dependent_1 * 2.5 |
Computation option: physical | 2 | 2 * 10.3 = 20.6 | 20.6 * 2.5 = 51.5 |
Result after rounding | 2 | 17 | 52 |
Computation option: physical + limited | 2 | 2 * 10.3 = 20.6 | 17.4 * 2.5 = 43.5 |
Result after rounding | 2 | 17 | 44 |
Computation option: quantized | 2 | 2 * 10.3 = 20.6 | 21 * 2.5 = 52.5 |
Result after rounding | 2 | 17 | 53 |
Computation option: quantized + limited | 2 | 2 * 10.3 = 20.6 | 17 * 2.5 = 42.5 |
Result after rounding | 2 | 17 | 43 |
