Set-up, Calculation x, "Addition/subtraction" task
The following menu window only appears when using the calculation as an "Addition/
subtraction" task:
Fig. 23: Set-up, Calculation x, Addition/subtraction task
Task: For selecting the task used "Addition/subtraction".
Addition/subtraction: can only be used for impulse counter, event+operation
time, operational time, quantity from time.
Formula: Description of the calculation. Cannot be changed (just for your information).
Channel ident.: Explanation (or designation of the calculation carried out here).
Input "y1": Input "y1", which is to be combined with another.
!
Other combinations can be used if their number is lower than the number of the
current combination. In this way, for example, calculation 1 can be further
processed in calculation 2 ("Cascading").
Factor "a": Factor "a", by which the value from signal "y1" is multiplied.
Factory setting: 1.
Calculation "?": Addition/Subtraction: adds or subtracts both channels / formula parts.
"Not used": switches part 2 of the formula (y2*b) off.
Input "y2": Input "y2", which is to be combined with another.
!
Other combinations can be used if their number is lower than the number of the
current combination. In this way, for example, calculation 1 can be further
processed in calculation 2 ("Cascading").
Factor "b": Factor "b" with which the value of signal "y2" or the function g (y1/y2) is
multiplied.
Factory setting: 1.
Constant "c" Constant "c" is added to the result of the combination of both signals "y1" and
"y2". Entry in this combination's (technical or physical) unit.
Factory setting: 0.
Engineering unit: Combination's technical (physical) unit, e.g. "piece" for summation of produced
units.
Decimal point: Number of places after the decimal point for the display and the limit value entry
(counter limit value).
Display: The results of the calculation are saved at defined intervals (e.g. daily, monthly,
etc. - see "Signal analysis"). Here, the counter type is selected that is to be
displayed constantly.
