Hold Flag

Following the main characteristics of the _HOLD_SFC flag:
  • default value is FALSE;
  • when set to TRUE, the SFC block, which is referred to ( the one with the same name as ), it is kept in the current status (hold) and no code is executed;
  • when the flag is set back to FALSE, the SFC block execution is recovered from exactly the same point in which was set to hold, trough _HOLD_SFC := TRUE.
