Real Time Updates

Integration with Alarm Analysis for exploring the Alarm Response Manual.

Right click on an Alarm and link through to the Alarm Response Manual (ARM) display on Bad Actor Detail page of Alarm Analysis.

NB. This assumes that you have uploaded and ARM to Alarm Analysis.

Context Filters

Right click on any event and select one of three new filters:

  • Context Before - Open a new SoE tab showing records leading up to the event.
  • Context After - Open a new SoE tab showing records following the event.
  • Context - Open a new SoE tab showing records in a 2min period around the event.

Easy Filter Date Formats

SoE now uses ISO 8601 date formats (e.g. “2021-11-25 23:03:01”).

The advantage of this format is that it facilitates easy filtering. For example, you can include a Time Stamp Filter on all or part of the date.

  • Time Stamp > 2021-11-25 23:03:01 - Show all events after this time
  • Time Stamp > 2021-11-25 23 Show all events after 11pm
  • TimeStamp > 2021-11-25 - Show all events since 25th Nov
  • Time Stamp > 2021-11 - Show all events since Nov
  • Time Stamp > 2021 - Show all events since 2021

Extended Field Filtering

SoE now supports filtering on non-core fields. These fields (exposed under “hidden fields” in the field manager) can include useful site-specific additional values.

Row Highlighting

Clicking a row puts it a highlighted on it. This simple feature helps track of rows of interest.

Hide Filter Panels

Dedicate more of your screen space to the SoE view by collapsing the filter panels.


  • Excel Friendly Dates
    The CSV export funtion has been adapterd to return TimeStamp in an Excel-friendly local time (i.e. in the TimeZone of the person downloading the file).


  • New Feature: Hidden Fields
    Besides showing the standard fields of an Alarm & Event journal, SoE Explorer now also supports display, sort and filter functions on non-standard “hidden” fields. Whether any such fields actually exist will depend on the configuration of specific import flows, but it may contain “import information” (e.g.filename and line number references for data imported from textfile) or extended alarm information particular to certain SCADAs.
  • Minor bug fix to the Export to Excel function - certain reserved characters could previously trip it up (#1959)


This release contains the following changes:

  • Minor bug fixes when the main view wasn't getting sorted by the event timestamp (#1724).
  • Bug fixes when not all fields were exported to Excel (#1723).
