“Continuous Function Chart”: CFC is a graphics language based on the use of Function Blocks and Functions that are combined to create a control logic.
FBD
“Function Block Diagram”: FBD is a graphics language based on the use of Function Blocks and Functions that are combined to create a control logic.
Function block
Functional container that runs various tasks depending on the connected logic inputs and outputs.
I L
“Instruction List”: IL is a command line programming language and is comparable to an assembler program. It basically consists of stacks that are used in sequence to run the requested functions
LD
“Ladder Program”: LD is a graphics program that resembles the structure of electrical drawings. In general, LD represents electrical connection logics that are built by using basic elements such as contacts, coils, and connection lines.
PLC
Programmable Logic Controller
SFC
“Sequential Function Chart”: SFC is specific for the control of machine / system sequences requiring “sequential” control. SFC language facilitates the configuration and on-line test of flow control.
ST
“Structured Text”: ST is a “high-level” language which, like IL, is based on command line instructions. As opposed to IL, the control code is not written based on the use of stacks but instead on the use of instructions that are freely insertable in the code.
