The Special I/O Units (Blue letters on part number on front of the card).The memory areas for the modules cannot overlap.  Typically each special I/O module takes the space of one unit number.  However, the CT021 uses 4 slots. If you have a unit #0 CT021 module, it uses the space reserved for unit #0 - 3 and the next module should be at unit #4 and would then use the space reserved for units 4-7.
