eAPP 3530: SEL-3530 Real-Time Automation Controller (RTAC)

PDHs: 24
Course Based Fees: $1,500*
* Plus Applicable Tax


This course is a hybrid version of APP RTAC that includes both eLearning portions and live virtual sessions. On average, it takes about 24 hours to complete this course during its scheduled three-week duration.

eAPP 3530 will guide you through configuring a realistic communications scheme using the SEL-3530 RTAC. The course starts with a live, introductory session with the instructor to help you get started. Each week, you will then watch the applicable recorded lectures and complete the exercises on your own. At the end of each week, the instructor will hold a virtual Q&A session to review what you learned. At the end of the course, you must return the SEL equipment; however, you will have access to the eLearning content for eight weeks.

eAPP 3530 is only available to students in the US and Canada. If we currently do not have any eAPP 3530 courses scheduled, select “Contact Us” to be added to the waitlist.


This course is intended for engineers 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.

You must return the SEL equipment provided for use during the training within 1 week of course completion. If you fail to return equipment, SEL may charge your credit card for its retail cost.

Learning Outcomes

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

  • Describe the expectations of modern integrated automation communications systems.
  • Describe typical RTAC system applications.
  • 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 perform common operations, such as reading/sending and backing up/restoring settings.
  • 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 the Network Time Protocol.
  • Create user logic programs and functions with the IEC 61131-3 programming language in continuous function chart, structured text, and ladder diagram languages.
  • Manage security and logic settings according to NERC CIP requirements.
  • Configure the RTAC to communicate to either a DNP3- or Modbus-based SCADA system.
  • Configure the RTAC HMI for status and control.

Student Background and Knowledge

Before you attend this class, we recommend that you:

Course Preparation

Make sure your laptop has the following features and updated software:

To operate correctly, acSELerator RTAC requires the specific network TCP ports listed below to be open. You can enable the ports by either turning off or adding exceptions to the firewall and antivirus software on your computer. Please work with your IT department to ensure they are open before attending this course:

  • 5432 (TCP Incoming): acSELerator RTAC project download/retrieval
  • 1217 (TCP Incoming): acSELerator RTAC online status monitoring and point forcing
  • 5433 (TCP Incoming): RTAC firmware upgrades
  • 15453 (TCP Incoming): Communications Traffic Monitoring for diagnostics/testing
  • 443 (TCP Incoming): HTTPS (RTAC web server)
  • 514 (TCP Incoming and UDP Listening): Syslog Watcher
  • 80 (TCP Incoming): HTTP (RTAC web server)
