Application of the add-on block library
Function Chart |
Static test of alternative and parallel branches nested one into another. Closed loops without the ZA block (X100) contain the ZE block once always (X200, X300). Events (EA_x, EM_y and EU_z) are simulated by means of manual switches. No variables are transmitted. The states (ZA, ZX and ZE blocks) may be activated several times depending on the functional sequence. Regardless of this, the one sequencing event deactivates a state.
