our software Function Block Editor allows you to directly write C language programs. More suitable for experienced programmers who are familiar with C language and programming. C language allows you to create programs that cannot be created through ladder logic, functional block diagrams, or even instruction list editors. This is because you are programming in the native language of this series of PLCs, not limited to the standard structured programming solutions provided by the Electrical Society (IEC).

For safety reasons, function blocks cannot directly call ladder diagram instructions
