Course Information

This is a three-day course.

Course Base Fees: $1,800 USD

APP 3530 ADV-1 is a highly interactive and activity-based course that builds on the content covered in APP 3530. During the course, you will learn and apply the advanced logic functions of the SEL Real-Time Automation Controller (RTAC) to create IEC 61131-3 programs, functions, and function blocks. We will discuss operational devices, such as the program organization unit (POU), and will cover POU pin functionality and the use of library functions. You will learn how to program the RTAC using tools and building blocks to build custom applications.


APP 3530 ADV-1 is for engineers and technicians who want to move beyond basic data collection and concentration in the SEL RTAC and learn more about IEC 61131-3 and advanced logic.

    • ChannelMonitoring
    • PowerMetering

Student Background and Knowledge

Before you attend this class, we recommend that you take APP 3530: Real Time Automation Controller (RTAC) OR have experience with SEL relays, understand Boolean and math-based logic, and know how to:

  • Perform the initial setup of an RTAC.
  • Create an RTAC project.
  • Add devices to an RTAC project.
  • Use acSELerator QuickSet SEL-5030 Software to configure basic relay communications.
  • Use acSELerator RTAC SEL-5033 Software to create an RTAC project, configure IED communications, and perform online operations, such as sending a project, viewing live data, and forcing tag values.
