FBD
Function Block Diagram is one of the PLC programming languages specified in IEC61131-3 and can be easily utilized by encapsulating circuit blocks that are repeatedly used in the sequence program.
The features of Function Block are as follows:
Encapsulation of the Program: By displaying the standard program in one block (capsule), users can easily reuse the program by copying and pasting the block. Also, by simply compressing a large program into a small and single block, users can easily edit and debug the program with enhanced readability.
Quality Maintenance of the Program: By reusing a component of the program, users are able to obtain consistent quality of the program without depending on the skill of the program developer.
Encryption of the Program: You can prevent other users from editing the program by function block password settings to protect the internal program.
