FBD Language Example
FFLD Language Example
- In the FFLD Language, the input rung (EN) enables Enable signal for the drive, Hardware-Enable with 24V signal to X8, Software-Enable command by setup Software, fieldbus or permanently set.
Both are required for enabling the drive. the selection.
- The output rung keeps the state of the input rung.
- The selection is performed only if EN is TRUE.
- ENO has the same value as EN.
IL Language Example
- In the IL Instruction list - This is a low-level language and resembles assembly. Language, the first parameter (selector) must be loaded in the current result before calling the function.
- Other inputs are operands of the function, separated by comas.
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. SELECT
