Detailed Definition
Captures current input pattern into sequencer array position. This term is essential for understanding ladder logic in industrial automation and PLC programming.
In ladder logic — the most widely used PLC programming language and the foundation that the IEC 61131-3 standard formalises — Sequencer Load is one of the building blocks that turns electrical-engineering reasoning into executable PLC code. Captures current input pattern into sequencer array position.
Inside the scan cycle, Sequencer Load is processed during the program execution step. Its behaviour is deterministic — given the same inputs, it always produces the same outputs in the same time — which is exactly what industrial control demands.
Mastering Sequencer Load is part of becoming productive in ladder logic — the language in which roughly 80% of industrial automation is still written. Visual readability is the reason ladder hasn't been displaced; engineers continue choosing it for binary logic and machine sequencing.
