Rectangles representing specific states of the process (e.g., "Wait," "Close Door").
Below is an essay that explores the technical significance and application of this standard. sc25582-SFCS.part3.rar
This state-machine approach is ideal for processes like elevator control or assembly lines, where parallel branches can execute simultaneously. For instance, a system might monitor safety sensors in one branch while controlling mechanical movement in another. Application in Modern Systems Rectangles representing specific states of the process (e

The filename appears to be a compressed archive, where "SFCS" likely stands for Sequential Function Charts . This is a specialized programming language defined by the IEC 61131-3 standard for industrial automation and control processes.
Conditions that must be met (e.g., a sensor being triggered) before moving from one step to the next.
