WEBserver HMI

Orion WEBserver

Orion WEBserver is a web-based SCADA and local HMI solution that uses open-source web technologies to build interactive screens accessible from standard web browsers. A browser can connect to an Orion and view data from connected IEDs and RTUs. Displays can range from a single text-based screen to detailed substation one-line drawings with multiple password protected drill-down screens for viewing IED data or establishing a pass-through connection with the IED. WEBserver has pre-configured pages for Data Archiving/Sequence of Events Recording, Alarm Annunciation, one-line diagrams, IED faceplates, control screens, alarms, trending,  and communications diagnostics.

Custom Screens

Page graphics (including active/inactive color states) are created using the no-fee Inkscape .svg page editor. Data points to be monitored and controlled are defined in NovaTech Communications Director (NCD) software (using XML Server protocol), along with logic for object state changes. Pages and interactivity are then transferred from the PC to an Orion and integrated with standard OrionLX pages.

Pre-formatted Pages

The Sequence of Events (Archive)

Allows you to view binary and analog data changes. The user configures the desired points in the Alarm- Archive-Retentive (AAR) module in the OrionLX offline configuration tool – “NCD”. Binary points are displayed when the value changes state, and analog values are displayed when the values change outside user-defined limits. Values can be archived based on time and/or value change. Both the IED time stamp and the Orion time stamp are provided to simplify identification of incorrectly time-stamped points.


Allows you to view binary and analog data in three alarm states:

  1. In alarm and unacknowledged
  2. In alarm and acknowledged
  3. Returned to normal but unacknowledged

The user configures the desired points in the Alarm-Archive-Retentive (AAR) module in NCD, along with the associated alarm message text to display on the alarm page. Multiple thresholds can be set for analog alarms – Lo, LoLo, Hi and HiHi. Users have the option to acknowledge alarms if their pre-set user privileges permit.

Tools are provided to simplify access and viewing of Alarm and Archive records:

  1. An “Alias” can be defined for any point
  2. Clicking on a heading multiple times will switch between ascending and descending order
  3. A time/date “window can be set to hone in on the desired data


Allows you to view binary and analog data in a graphical format. Any point the user configures in the Archive portion of the AAR module becomes available for trending. Up to eight pens can be graphed at the same time. Archive and Alarm points are stored in non- volatile memory (1GB or 4GB) in an open relational PostgreSQL database. Standard SQL queries or .csv file transfers are alternatives to viewing data in webpages.
