IEC specifies the syntax and semantics of a unified suite of programming languages for programmable controllers (PCs). This suite consists of two textual languages, Instruction List (IL) and Structured Text (ST), and two graphical languages, Ladder Diagram (LD) and Function By means of instantiation IEC unifies the usage of manufacturer-dependent FBs (typically timers and counters) and user-defined FBs.
