FBD Language Example
FFLD Language Example
- In the FFLD Language, the operation is executed only if the input rung (EN) is TRUE.
- The output rung (ENO) keeps the same value as the input rung.
- The function is executed only if EN is TRUE.
- ENO keeps the same value as EN.
IL Language Example
- In the IL Instruction list - This is a low-level language and resembles assembly. Language, the input must be loaded in the current result before calling the function.
Op1: LD Ladder diagram - This is a method of drawing electrical logic schematics. It is a very popular graphical language for programming Programmable Logic Controllers (PLCs). It was originally invented to describe logic made from relays. The name is based on the observation that programs in this language resemble ladders, with two vertical rails and a series of horizontal rungs between them. INFO
