Subchart Dummy Steps
The specific results of executing SP(211) for steps in each step status are de-
scribed below for dummy steps controlling subcharts.
Execute Changes the status of the subchart dummy step from execute to pause. All ac-
tive steps in the designated subchart (including those in halt status) will be
placed in pause status. Execution of actions will be paused, but output status will
be maintained and the step timer will continue. If SP(211) is executed for a sub-
chart from within the same subchart, the actions within the only step containing
SP(211) will be paused beginning with the next execution cycle.

Normal Steps Status
The specific results of executing SR(212) for steps in each step status are de-
scribed below for normal steps inside or outside of subcharts.
Execute Step status does not change.
Pause Changes the step status from pause to execute. Execution will be resumed from
the beginning of the subchart, and output status will continue with the status that
existed at the time the step was changed to pause status.
Halt, Inactive Step status does not change.

The specific results of executing SR(212) for steps in each step status are de-
scribed below for dummy steps controlling subcharts.
Execute Step status does not change.
Pause Changes the status of the subchart dummy step and all steps in the subchart that
are in pause status from pause to execute. Execution will be resumed from the
