The BOOTP/DHCP server also limits the possibility of assigning
duplicate IP addresses.
• company policies and procedures associated with plant floor network
installation and maintenance.
• level of involvement by information technology personnel in plant floor
network installation and maintenance.
• type of training offered to control engineers and maintenance personnel.

subnet where an enterprise DHCP server exists, a module may get an address
from the enterprise server before the Rockwell Automation utility even sees the
