do any of you know how it would apply ?
How does ladder logic apply to programable logic control
Click For Summary
Ladder logic is a graphical programming language used in programmable logic controllers (PLCs) that resembles traditional relay logic diagrams, making it straightforward to troubleshoot. Each symbol in ladder logic indicates the status of inputs and outputs, clearly showing what conditions must be met for processes to proceed. While other programming methods like structured text and function block programming are also utilized, they are often considered less intuitive for troubleshooting. The simplicity of ladder logic contributes to its popularity, especially in environments using Allen-Bradley (AB) or Rockwell PLCs. Overall, ladder logic remains a preferred choice for many due to its visual clarity and ease of use.

The PLC program is sometimes represented by "ladder logic". It looks similar to an old relay logic print and is simple to troubleshoot.
Each symbol highlights when true so it is obvious what is required for the process to continue...
This is AB or Rockwell
Structured text and Function block programming are also commonly used but are not as easy to troubleshoot IMHO.
