1. Stepped ladder diagram editor
Oursoftware Step Ladder Diagram (SFC) editor allows the creation of a flowchart program format for sequential control design based on the mechanical action flow. SFC is more appropriate for the concept of state machine and is more suitable for writing programs that perform corresponding actions in different states.
图1 Example of Step Ladder Diagram Program
Various instructions are represented by graphical symbols, including three basic forms.
| Graphic | Name | Description |
|---|---|---|
 |
initial status | The initial state of the sequential control program, which is only active in the initial state. |
 |
status | A state of the sequential control program that is initially closed. |
 |
Conditional Transition | When the upper state is active and the transition condition is conductive, the upper state will be turned off and the lower state will be turned on. |
 |
Single Horizontal Line | Horizontal Line connects multiple conditional transitions. |
 |
Double Horizontal Line | Horizontal Line connects multiple states. |
1.1. key points
The key points to consider when choosing an STL editor include:
The sequential execution of action flow, with different actions executed at different stages.
When expressing the flowchart clearly and intuitively.
