2 Plant structure

2.1 Plant topology

The plant topology shows the physical circumstances and conditions of the
machines with the NC data storage system and their hierarchical structures in
MCIS DNC. DNC offers the following hierarchical levels for mapping production:

Groups

Machine
DNC contains the "workpiece" folder for bundling the NC data for a workpiece.

Group
NC data management allows basic and detailed hierarchical levels to be created by
means of the group hierarchical level. For example, you can combine several
machines of the same type into one group. You can then subdivide these groups
further into subgroups. You can also manage individual items of NC data and
workpieces within each group.
Machines can also be created without a higher-level group.
Note
You can insert groups by choosing File  New  Group. Depending on the
selections you made in the tree view, you can insert groups before or after the
current hierarchy level. To insert groups one hierarchy level lower, choose
File  New  Subgroup.
