Learn about the challenges and drawbacks of using sequential function charts (SFCs), a graphical programming language for PLCs, such as syntax, scalability, testing, and alternatives.

If you want to program a PLC (programmable logic controller) using sequential function charts (SFC), you need to understand the basic elements and steps of this graphical language.

“That subroutine would be a Function Block. Then, within the Sequential Function Chart, the Function Block becomes a unique file.” Those PLCopen Function Blocks offer many advantages, emphasizes Rami ...

Tom Jensen Senior Technology Evangelist for ELAU has developed a best practice for implementing the state model in ELAU’s IEC 61131-3 based PacDrive™ control application using Sequential Function ...

Sequential table look-up algorithms are proposed for the evaluation of ln x and exp x. Tables of pre-computed constants are utilized in transforming the argument into a range where the function may be ...
