Code rt_plc_macro_grafcet.h 
 Conditional execution of objects located in a
 Sub-window.


 The code in the sub-window is,
 executed if, and only if, the logical input signal is
 TRUE; compare with an ordinary Order object where
 execution is done as long as the input is TRUE and
 after that further once, i.e. an Order object is
 always executed at least twice.
 put below a WindowPlc object (see p. 3-396) below the
 CSub-object.

 The input is connected to any logical signal; an Order
 object is only connected to Grafcet-steps.

 By means of the Attribute Editor the value of the input
 signal can be inverted.
 The sub-window may contain PLC objects without any
 known restrictions.
