Slot Numbering
The DL205 bases each provide different numbers of slots for use with the I/O modules. You
may notice the bases refer to 3-slot, 4-slot, etc. One of the slots is dedicated to the CPU, so
you always have one less I/O slot. For example, you have five I/O slots with a 6-slot base. The
I/O slots are numbered 0–4. The CPU slot always contains a PLC CPU or other CPU–slot
controller and is not numbered.
