Each technological unit is represented by one row of a structured variable.
The D2000 supports the creation of:
- structured eval tags - one calculation for all lines of the structure
- structured historical values
- primary - archiving of the entire column of the structured variable
- calculated - one calculation of the expression for all rows of the structure
- statistical - one calculation of statistics for all rows of the structure
- filled from the script
- instance pictures (schemes) - the instance picture displays values from the N-th row of the structured variable. The instant picture can be inserted multiple times into the standard picture and thus repeatedly display data from specific rows
- instance graphs - similarly to an instance picture, a graph can also display values from the N-h row of a structured variable. Instance graphs can be opened from both instance and standard pictures.
Example
Let's have several PLCs, each of which has a name and three temperatures T1, T2, and T3, which are obtained from communication. We want to calculate the average of these temperatures and also display the communication status. We want to calculate a 5-minute weighted average from the average temperature (using the archive).
