Ladder Diagram
A graphical programming language used in PLC programming, composed of graphical elements such as contacts and coils together with their wiring relationships. It requires a graphical editor for direct editing.

An Agent can generate programs in .awl format and import them into the 200SMART software; after import they are displayed in the STL language, but can be switched to ladder diagram view within the software.
STL (statement list) is a textual programming language in the IEC 61131-3 standard; ladder diagram (LAD) is a graphical language, composed of structured data made up of graphical elements such as contacts and coils along with coordinates and connection relationships.
Ladder diagram and STL cannot always be converted between each other losslessly: after some complex logic is exported from LAD to STL, it may no longer be restorable to the original ladder diagram when read back.
