Relay Integration

Relay Data Retrieval Simplified

Select Points, Automate Default File Creation, and Manage Connection Scenarios

NovaTech currently provides over 200 pre-engineered SEL® “point pick lists” (or “Default Files”) to simplify the process of selecting points from SEL® relays. When new SEL® relay models are introduced, NovaTech Engineering, or the user, creates a new Default File for that specific new relay model. Relay Helper is including in the SEL® Master protocol (order code #14).

OrionLX Relay Helper simplifies the Default File creation process by automating the extraction of SEL® relay “ID” and “DNA” from the new relay model. Using these data, Relay Helper automatically creates the new complete and accurate Default File. The entire process takes just a few minutes and utilizes four software wizards, each addressing a different connection scenario for Default File creation:

Wizards 1 and 2

Used when the user PC is connected to the OrionLX and the OrionLX is connected to the relay. Relay ID and DNA are automatically extracted from the relays. Wizard #1 creates a new NCD file and Default Files with “found” relays; Wizard #2 adds “found” relays and Default Files to an existing NCD file.

Wizard 3

Used when the user PC is connected directly to the relay. Relay ID and DNA are automatically extracted from the relay and a Default File for the connected relay is created and added to NCD.

Wizard 4

Used when the PC is offline and has a copy of the relay ID and DNA. A Default File for the relay is created and added to NCD.

Wizard Comparison

Function Wizard #1 Wizard #2 Wizard #3 Wizard #4
Creates a new NCD file with found SEL relays X
Adds found SEL relays to existing NCD File X
Finds baud rate with new Autoband feature X X
Access FID and DNA from SEL relays X X X
Uses FID and DNA from SEL relays to create or modify a default file X X X X
Sends email notification to NovaTech Engineering when a new Default File is created or an existing file modified X X X X

Guidelines for Application of Relay Helper

  1. The SEL® relay must support Fast Meter and the “ID” command
  2. Wizard 1 and 2 are not designed to work with Cascaded OrionLX configurations
  3. For a new Default File to be created, a Default File for a relay of that “family” must already exist in NCD
