Other Factors to Consider When Assigning Network Parameters
There are other factors to consider when assigning network parameters, which
include the:
• network isolation from or integration into the plant/enterprise
network.
• network size.
For large networks, even isolated networks, it might be more convenient
and safe to use a BOOTP/DHCP server rather than RSLinx software.
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.
If the Rockwell Automation BOOTP or DHCP server is used in an uplinked
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
