Extended Trendmodule (ETM)

 |
The Extended Trend Module (ETM) is a sophisticated tool to graphically depict values in curves. Recorded historical data (from archives or HD data) can be depicted as well as online data that is not saved.
Any number of curves
Any number of curves can be depicted simultaneously, even with varying scaling. Each curve has its own y-axis that can be freely parameterized. The Trend can be used for time-controlled depictions (yt) as well as for the depiction of locus curves (xy).
Equidistant as well as non-equidistant values:
The zenon Trend Analysis supports the processing of equidistant as well as non-equidistant values including correct interpolation.
Scan
With this special ETM feature the curves can be scanned with a ruler. The curves’ values where the scan ruler is tangent to the curves are displayed. In the same way the units of measure, the status, date as well as minimum, maximum and average values can be displayed along with variable values. The tying in of the curves occurs through freely definable filter settings (see Filter).
Two time axis
ETM can simultaneously depict two time axes in a diagram. This way, different time periods or batches can be easily compared with each other.
Automatic refresh
In order to achieve a continuous trend curve, the trend is set to automatic refresh. This allows you to always display the most current values on demand. In order to precisely analyze or measure especially important segments, the Trend can be paused as well as freely scrolled and zoomed.
Convenient printing functions
On all Windows printers, no matter if local or in a network, it is possible to generate color and black & white printouts with headers, footers, legends, captions, etc. With the practical clipboard button, the currently displayed trend can be copied as a vector graphic in the temporary storage. This snapshot can be used in other programs, like Word, for documentation purposes.
Dynamic Trend Element
The trend element is part of the standard functionality of zenon and can display HD data. The curve colors and forms can be freely defined. All curves are scaled as a percentage of the measuring range resolution of the variable.
