4. FC language
Flow Chart (FC) is a graphical language used to describe sequential operations. An FC diagram is made up of actions and tests.
Between actions and tests are oriented links representing the flow of information.
Actions and tests can be described using ST, LD or IL languages. Functions and function blocks written in any of these languages (except SFC) can be called from actions and tests.
An FC program can call another FC program. The called FC program is a sub-program of the calling FC program.
