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 Language, the input must be loaded in the current result before calling the function.

Op1: LD       IN
     ScaleLin IMAX, IMIN, OMAX, OMIN 
     ST       OUT

ST Language Example

OUT := ScaleLin (IN, IMIN, IMAX, OMIN, OMAX);
