Determine Module Slot Location
Figure Slot Locations shows chassis slot numbering in a four-slot chassis. Slot
0 is the first slot and is always the leftmost slot in the rack (the first slot to the
right of the power supply). You can use any size ControlLogix chassis and
install the module in any slot. You can also install multiple 1756-DH485
modules in the same chassis. You can install as many modules as your power
supply can accommodate (that is the number for which the power supply is
rated).
