Module Placement
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 CPU or a base controller (EBC)
or Remote Slave and is not numbered.
