What programming language is used for relay protection
Smart relays generally use proprietary programming languages developed by the manufacturer, which are typically visual or graphical programming languages. However, most of these are based on industry standards, particularly IEC 61131-3. A basic understanding of Boolean expressions and methodologies is helpful in developing the required programing to obtain the desired logic and for effectively using the full power that is designed into numerical relays. This complimentary eLearning course teaches you how to read, set, and test SEL relay logic as you identify Relay Word bits and SELogic operators and visually interpret diagrams. To do so, first, you will learn about the IEC 61850 standard, including the concept of this. The complexities for designers be-gins with the fact that to operate with these programmable products it is necessary to know at least one apparatus de-scription language — Verilog VHDL, which differs consid-erably from the traditional microcontroller programming lan-guages (C and Assembler).
