APP 2240: SEL-2240 Axion Distributed Control and Integration Platform

PDHs: 23

Course Base Fees: $1,500*
* Plus Applicable Tax


Course Information

This is a three-day course.

Course Base Fees: $1,500 USD

The APP 2240 course is designed to be highly interactive and activity-based. During APP 2240, in groups of two, you will configure a realistic communications scheme using the SEL-2240 Axion Distributed Control and Integration Platform. Each section of this course will guide you, step by step, through configuring this communications scheme.


This course is intended for engineers, technical consultants, and technicians who have an understanding of:

  • Boolean, math-based, and IEC 61131-3 logic.
  • Power system topology and architecture.
  • SEL relays, communications methods, and protocols.


Day 1

  • SEL Axion Product and Automation Overview
  • Initial Setup and Security
  • acSELerator RTAC SEL-5033 Software Overview
  • RTAC DNP/IP Client/SEL-351S Server
  • RTAC Modbus TCP Client/SEL-351S Server

Day 2

  • RTAC SEL Protocol Client/SEL-351S Server
  • RTAC-Tunneled Relay Engineering Access
  • RTAC Time Synchronization and SOE Logging
  • Mirrored Bits Communications and IEC 61131-3 Introduction
  • RTAC IEC 61131-3 User Logic

Day 3

  • RTAC DNP/IP Server
  • RTAC Modbus TCP Server with Simple Tag Mapper Extension

Course Outcomes

At the conclusion of this course, students will be able to:

  • Discuss the expectations of modern integrated automation systems.
  • Name common Axion system applications.
  • Identify various Axion modules and explain how the EtherCAT protocol is used to communicate with the modules.
  • Use the RTAC web interface to configure settings such as user accounts and for troubleshooting purposes such as reading status and alarm logs from the RTAC.
  • Use acSELerator RTAC to efficiently manage RTAC settings and to perform common operations, such as reading/sending settings and backing up/restoring them.
  • Use acSELerator RTAC to configure the EtherCAT protocol to communicate with the Axion I/O modules.
  • Identify and properly configure DNP3, SEL, Modbus, and Mirrored Bits communications protocol application settings.
  • Configure the RTAC to allow engineering access to connected IEDs.
  • Configure the RTAC to accept and provide time synchronization using a variety of methods, such as IRIG-B and Network Time Protocol (NTP).
  • Create user logic programs and functions with the IEC 61131-3 programming language in continuous function chart, structured text, and ladder diagram languages.
  • Configure the RTAC to communicate to a DNP3-based SCADA system.
  • Configure the RTAC to communicate to a Modbus-based SCADA system using the Simple Tag Mapper extension.
  • Configure the RTAC HMI for status and control.
