Digital Recorder
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.
Copy settings: Copies the settings for this calculation into the selected calculation (incl. limit
values). Both of the last positions of the target channel's designation are
replaced with its channel number.
Tip:
Makes device setting easier, if the same settings apply largely for several
combinations (e.g. several counter sums).
Alarm setpoint x: Settings only required if the result of the combination is also to be monitored for
limit values.
For detailed settings, see digital input limit value settings.
Set-up, Calculation x, "Logical combination" task
The following menu window only appears when using the calculation as a "Logical
combination" task:
Fig. 25: Set-up, Calculation x, Logical combination task
Task: For selecting the task used "Logical combination".
Logical combination: can only be used for on/off event, operational time and
event+operation 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").
Logic cond. "y1": Logic condition of input 'y1' at which the selected calculation takes effect.
Note!
