To search for signal data, click Add signals button

Select the type of signal you want to search for.

Select SEARCH

Once you have the signal, you can choose the ones you want by clicking on SELECT

You can select the signals that remain.

After finding requested signals the users should specify the point of view they are requesting.

DATA FROM – start of the requested data range

DATA TO – end of the requested data range. May be specified either relatively (day, week, month, quarter, half-year, year, two years or ten years) or absolutely (value custom)

INTERVAL – represents the aggregation interval (one value per second/minute/hour/day) or raw data

STEP – aggregation step (usually 1 which means one value per one hour, etc.)

AGGREGATION – aggregation method (OPC aggregation method such as Interpolative, Average, etc.) or TXP aggregation which should correspond to the aggregation method of the original system

Cuando estén todos los datos, haremos click en DISPLAY

Once the point of view is specified, users may show charts with signal values.

Display – shows separate chart for each signal

JointDisplay – show one chart containing all selected signals as separate series

PointsChart – available only if exactly two signals are selected – the values of signals are used as axis points.

Charts allow additional user interactions – user may:

Browse through the previous/following time intervals using the left/right arrows

Download chart as a PNG image

Configure various aspects of the chart (series colors, axis) or zoom time range series using quick sliders

Zoom chart to the whole screen

There is a small icon next to the KKS sign that shows information in small

Also shows full detail of the signal

Signal data may be exported either for one signal or for all signals at once.

Click Export

Exact time can be specified in the Export dialog (using hour, minutes and seconds) as well as export format (CSV or XLS).

Joint export is not available for exporting raw data (as there is no way to pair particular values)

Users can save the list of frequently used signals in the so-called Group and can be private or public

Select GROUPS and SAVE AS

Enter group name

Select private or not

Once the group is saved, user may get back to the list at any time by simply opening the group.

Alarm management serves as a browser page for Sequence of Events (SOE) data.

Select ALARM MANAGEMENT

The range can be specified either relatively (as a minute/hour/day/week before a timestamp) or absolutely (using custom range between two timestamps).

The events can be filtered using their event types or by the properties of corresponding signals (eg. Unit/System/Equipment/Signal/Description).

Selected events can be exported into a CSV file by pressing the Export button at the bottom of the page.

????

Events quantities provides a quick overview of the complete dataset. The overview represents separate columns for each event types.

W for warnings

T for tolerances

A for alarms

F for failures

OE for operator events

... for summary of other types of events

Each cell represents a particular time period (day/hour/15min/minute).

Particular value can be shown by hovering a mouse cursor over the cell.

Intensity of the color represents the number of events in particular cell

By clicking a cell, particular time range is selected and a detailed view is displayed.

The view can be filtered with respect to any functional area or their combination.

For reporting purposes, the view can be also saved as a PNG file using the button with image icon.

Detailed view allows users to precisely analyze the events inside the system, their exact timing, sequences and durations. Each row in this view represents a particular signals which appeared during the selected time range.

Signals can be reordered (by simple drag and drop on their label)

Hidden (by pressing the X mark next to the label of selected signal)

The whole list can be filtered by their type (typically for Alarms, Warnings, Failures, Tolerances, Operator Events) or by their nature (Engineered Signals or DCS Internal Signals)

Logical Diagram

The view can be zoomed (by dragging the zoom slider on the right top part of the page) or sorted.

Right bottom part of the page contains a quick preview of the selected time range with all signals at once (to quickly spot important timestamps).

Detailed view can be saved into a PNG picture by pressing the button with image icon.

Current state of the page can be saved at any time using so-called Reports.

Reports are created using the button Save as... and can be either public (all users can see them) or private (only for its creator).

If the OMLEX Historian application is configured in authorized mode, users are required to sign in prior using the application.

This user management is done through the settings icon on the right part of the menu.
