Obsolete instruction
Executes the program between the master control flag instruction MC and the master control flag end instruction MCE of the same number Num* if the execution condition at EN is TRUE.
This instruction (or variable) is allowed to be compiled because of the down-compatibility to lower versions but cannot be selected in the "Instructions" pane (or "Variables" pane) anymore.
As an alternative use:
“ST editor”: Selection statements e.g. IF/ELSE
“LD/FBD editor”: Jump
“SFC editor”: SFC control instructions
