Using DHCP Software to
Configure Your Adapter
What’s Next?
Configuring the 1794-AENT Adapter for Your EtherNet/IP Network 3-13
DHCP (Dynamic Host Configuration Protocol) software automatically
assigns IP addresses to client stations logging onto a TCP/IP network.
DHCP is based on BootP and maintains some backward compatibility.
The main difference is that BootP was designed for manual
configuration, while DHCP allows for dynamic allocation of network
addresses and configurations to newly attached devices.
Be cautious about using DHCP software to configure your adapter. A
BootP client, such as the 1794-AENT adapter, can boot from a DHCP
server only if the DHCP server is specifically written to also handle
BootP queries. This is specific to the DHCP software package you use.
Check with your system administrator to see if your DHCP package
supports BootP commands and manual IP allocation.
ATTENTION
!
The 1794-AENT adapter must be assigned a fixed
network address. The IP address of this adapter must
not be dynamically provided.
Failure to observe this precaution may result in
unintended machine motion or loss of process
control.
The following chapter describes an example application in which you
configure discrete I/O using a rack optimized connection.
