Maybe I started my components with a wrong concept. Each component,
represents a memory (or a set of memories) on a remote device (like a PLC)
that can be read and/or written. These components can be linked with edits,
labels, progress bars and others controls created to show/modifies/stores
the value of these components.

For now, I did only small projects using these components (using ~150 tags
or components). Today, I started my first big project. On the first time,
using the component wizard, I inserted 255*5+1 components. This action takes
some time. After this, I tried using my wizard again, to insert 4000
components, and after this the IDE freezes.

I thought use the TCollection, but I don't know if I can represent the
following configuration (it's a example, it can have how many PLCBlocks,
BlockItems, TagBit, PLCNumbers or PLCStrings the owner of project wants):

Owner (TCollection)
   |
   |-> PLCBlock (now, each below is a component)
   |       |
   |       |-> BlockItem (0..n items)
   |       |-> BlockItem
   |       |       |
   |       |       |-> TagBit (0..n items)
   |
   |-> PLCBlock
   |       |
   |       |-> BlockItem (0..n items)
   |
   |-> PLCNumber (0..n items)
   |       |-> TagBit (0..n items)
   |
   |-> PLCString (0..n items)

Some idea?


The best regards,

Fabio
