The NMpsStoreCell object is a container for data objects similar to the
 NmpsCell object.

 The differencs is that the NMpsStoreCell has a select
 function for each data object in the cell. When an object is transported
 from the cell at the rear end, the currently selected object will be
 transported. If no object is selected, the object with highest index is
 transported.

 A data object is selected by setting the Select attribute for the
 index of the data object. This can be done from an application or from
 the MMI. You can also select an data object with the extern fuction, by
 entering the objid for the data object.

 In the Function attribute, the number of currently selected objects can
 be specified to at most one, or exactly one.

• NMpsCell
• CurrentData
• CurrentIndex
• NMpsTrp
• NMpsTrpFF
• NMpsTrpRR

Connection to a transport object, NMpsTrp, NMpsTrpFF or NMpsTrpRR.

Data objects transported into the cell is inserted at the front end of the cell.
They will be inserted at first position and the other data object are
shifted downwards in the cell.

Data objects transported from the cell is fetched from the front end with
index 1. The other data objects are shifted upward in the cell.

Connection to a transport object, NMpsTrp, NMpsTrpFF or NMpsTrpRR.
Data transported into the cell is inserted at the rear end of the cell.
They will be inserted at first free position and the other data object
remains their position.

Data objects transported from the cell is fetched from the rear end.
The other data object remains their position.

 Maximum number of data objects in the cell. Larges MaxSize is 30.

Special functions of the cell.
Function is a bitmask, and the functions can be superimposed.

0   No limitations in the number of selected objects.

1   At most one selected object.
    If a new object is selected, the previously selected object will be unselected.

2   Exactly one selected object.
    If a new object is selected, the previously selected object will be unselected.
    If the currently selected object is removed from the cell, the
    object with highest index will be selected.

4   If an data object is removed from the cell by the extern function
    (ExternOpType=2,3 or 4) the data object is also remove from the rtdb
    database.

8   When the cell is reseted by the ResetObject, the dataobject is also
    removed from the database rtdb.

16  Backup. The cell and data objects in the cell, is backed up by
    the nmps backup process.

Digital object that will cause reset of the cell, i.e. all data object are removed.
Name of an attribute of type pwr_tBoolean. When the attribute is high,
all the data object are removed from the cell. If Function 8 is set, the objects
is also removed from the rtdb database.

Flag for interaction with the nmps backup process.
If the flag is set the cell is included in the next incremental backup.

Indicates that the cell i loaded from the nmps backup at startup.

Flag for interaction with nmps applications using the NMpsAppl API.

Flag that indicates that initiation should be done.

Flag for interaction with the nmps mirror handler.

Indicates that the cell is full. Number of data objects equals MaxSize.

Number of data objects in the cell.

Number of selected data objects.

The last occupied index in the cell.

Index of the current selected data object.

Indicates that a new object is inserted at front end of cell.
FrontNew is true in one plc scan.

Indicates that a new object is inserted at rear end of cell.
RearNew is true in one plc scan.

Objid for a data object that is inserted from an extern program.

Type of extern operation.

0   Insert ExternObjid into index 1 in the cell.
1   Insert ExternObjid into the index specified in ExternIndex.
2   Remove the object in index 1 in the cell.
3   Remove the object in the index specified in ExternIndex.
4   Remove the object with the objid specified in ExternObjid.
5   Select the object with the objid specified in ExternObjid.
6   Insert ExternObjid into index 1 in the cell, and select it.
7   Remove selection of object with objid specified in ExternObjid.
8   Move the object specified in ExternObjid one step forward in the cell
    (to higher index).
9   Move the object specified in ExternObjid one step backwards in the cell
    (to lower index).
10  Remove the object with the objid specified in ExternObjid. The object
    is not remove from the database, even if Function 4 is specified.

Indicates that an extern function shoud be executed.
When an application wan't to execute an extern function, it should
first fill in the other extern attributes and the the ExternFlag.
If there is a chance of collision between application programs,
you should check that ExternFlag is not already set.
The ExternFlag is reset by the cell when the extern function is finished.

Index in the cell where an object is to be inserted or remove.

Status of the last executed extern operation.

Pointer to data object with highest index.

True if the front of the data object with highest index is inside the cell.

True if the back of the data object with highest index is inside the cell.

Pointer to data object in index 1.

True if the front of the data object in index 1 is inside the cell.

True if the back of the data object in index 1 is inside the cell.

Selection of data object.
