Player reference manual

Recorded data and presentation

Player opens a .dpsplay recording and replays its saved states. It does not execute equipment models or scripts, interpolate unrecorded process states or edit numerical simulation results. Layout, chart configuration, the selected analysis interval and chart library are presentation data saved with the local recording.

Interface reference by task

Open and save commands

Save online is not exposed in the current desktop workflow. Online result storage is temporary delivery. Keep a local recording for later review and distribution. If a save fails, pending changes remain open so you can correct the problem.

Playback, time and intervals

Timeline wheel zooms; Shift+drag or middle-button drag pans. A time interval does not imply data exists at every instant in it. Changes between recorded cycles may be missed.

Route and inspector

Fit, zoom and Layout organize the view. Show analysis panel and Reset panel sizes restore a useful split. Select equipment or a stream to inspect its available recorded variables; search and the item selector help locate data.

SIM identifies simulation output; EXP identifies experimental/input data where supplied. A file can contain no EXP data. Size distribution and component views use the current recorded state. Aperture display can switch between µm and mm. Values remain read-only. Events and warnings and Run details provide recorded context, where present.

Trends and chart library

Double-click a variable, drag it to the recorded trend or use Add series. Series controls let you edit, hide, remove and choose the left or right Y axis. Keep labels and units explicit, especially when mixing quantities or SIM and EXP. The playhead cursor relates the time-series chart to the selected process state.

Chart configuration changes appearance. Add to library stores a configured plot in the current workspace; Chart library retrieves it. Save local retains the library in the recording. Export chart image produces a report figure. The chart may reduce points for display; this does not create or delete recorded samples.

Histograms, statistics and CSV

Analysis / Histogram–CSV provides a series selector, optional EXP inclusion and an inclusive From/To interval. Histogram settings include bin count, automatic or specified value range, Count/Percent/Density and cumulative distribution. Generate histogram reads the recorded data in that interval.

The summary reports included, missing/non-numeric and out-of-range sample counts, the included-sample mean and sample standard deviation. Frequencies count samples, not elapsed duration. Review exclusions before interpreting a statistic; it is not automatically a time-weighted process average.

Export series CSV uses all recorded rows in the selected time range, including missing values, rather than only chart display points. Select the separator and decimal-comma convention before export. A CSV or chart image does not retain the complete recording or editable project.

Optional script source

Scripts is enabled only when source was included by Developer before execution. The source viewer is read-only and permits reading and copying. It includes script metadata and can include disabled scripts. Player does not execute the code.

Omitted source cannot be recovered by Player. To provide a recording without source, generate it with source inclusion disabled in Developer; the documented Player workflow does not offer removal of included source. This choice does not conceal the recording’s remaining process data.

Local sharing and unsaved work

Use Save local as to keep a reviewed copy, reopen it to check the presentation, then send that file through an appropriate transfer method. Recipients need Player and access to the file. Include the study identity, relevant interval and Player version used. A managed or revocable sharing link is not part of this desktop save workflow.

On open/close with pending presentation changes, Save local retains them, Discard abandons them and Cancel returns to the workspace. This is an unsaved-work guard, not file encryption or access control. Keep your original recording when you need a baseline.

Troubleshooting

Chart editor and Chart studio are different stages

Library name is the saved-entry label; Chart title is the displayed title. Axis labels, limits, legend position and notes help make a saved review interpretable. A changed label is not a unit conversion.

Analysis fields and statistical population

Histogram and CSV may use different populations when manual histogram value limits exclude samples: CSV keeps all recorded rows in the chosen time range, including missing values. The chart display may reduce dense points, while analysis/export scans the recorded series.

A checked five-sample reference

The existing practice recording used for these new captures lasts 120 s and saves every 10 s. An inclusive 40–80 s interval produces five samples. Its feeder dry-solids series gives a mean of 9,916.9497074 t/h and sample standard deviation of 241.1289276 t/h, with no missing or out-of-range samples in automatic range. The native CSV export was checked independently and reproduced these statistics.

This reference checks the procedure. It is not a promised output of a fresh random run or evidence that the illustrative model is calibrated. Follow the full analysis exercise for the five rows and delimiter/decimal examples.
